Exposure to Radio Frequency Signals (SAR)  
Your wireless phone is a radio transmitter and receiver. It is designed and  
manufactured not to exceed the emission limit for exposure to radio  
frequency (RF) energy set by the Federal Communications Commission of  
the US government and Canada. These limits are part of comprehensive  
guidelines and established permitted levels of RF energy for the general  
population. These guidelines are based on the safety standards previously  
set by both US and international standard bodies.  
These standards include a substantial safety margin designed to assure the  
safety of all persons, regardless of age and health.  
The exposure standards for wireless mobile phones employs a unit of  
measure known as the Specific Absoption Rate, or SAR. The SAR limit set  
by the FCC and Canada is 1.6W/kg averaged over one gram of tissue.  
Tests for SAR are conducted using standard operating positions specified  
by the FCC with the phone transmitting at its highest certified power level in  
all tested frequency bands. Although the SAR is determined at the highest  
certified power level, the actual SAR level of the phone while operating can  
be well below the maximum value. This is because the phone is designed to  
operate at multiple power levels.  
Before a phone model is available for sale to the public, it must be tested  
and certified to the FCC that it does not exceed the limit established by  
government-adopted requirement for safe exposure.  
The tests are  
performed in positions and locations (for exampe, at the ear and worn on  
the body) as required by the FCC for each model. The highest SAR value for  
this phone when tested for use at the ear is 0.076W/kg, and when worn on  
the body is 0.018Wkg. (Body worn measurements differ among phones  
depending upon available accesories and the FCC requirements.) While  
there may be differences between the SAR levels of various phones and at  
various positions, they all meet the government requirement for safe  
exposure.  
For body worn operation, to maintain compliance with FCC RF exposure  
guidelines, use only Ascom approved accessories. When carrying the  
phone while it is on, use only the specific Ascom belt clip that has been  
tested for compliance.  
Use of non-Ascom-approved accessories may violate the FCC RF exposure  
guidelines and shoud be avoided.  
The FCC has granted an equipment authorization for this Ascom 9p23  
phone with all reported SAR levels evaluated as in compliance with the FCC  
RF emissions guidelines. SAR information on this 9p23 phone is on file with  
the FCC and can be found under the Display Grant section of  
http://www.fcc.gov/oet/fccid after searching on FCC ID 04M9p23.

Safety and Regulatory Information, Protection against Electrostatic Discharge (ESD)  
CHAPTER 3  
Protection against Electrostatic Discharge (ESD)  
3.1  
General  
Integrated circuits are sensitive to ESD.  
To avoid damage caused by ESD, service engineers and other people must handle equipment and  
boards carefully.  
Electronic equipment has become more resistive to ESD, but we see an increase of situations  
where static electricity can build up. This is caused by an increasing application of man–made  
fibers like nylon, acrylic, etc. which are capable of generating ESD of 10,000 Volts and more.  
Walking across a nylon carpet, even for a few feet, could cause a person to be charged–up to  
more than 10,000 Volts. Under these conditions, if a system board or a (C)MOS device is touched  
it could easily be damaged. Although the device may not be totally defective, it is often degraded,  
causing it to fail at a later date without apparent reason.  
To make sure that equipment and parts are well protected during shipment, special packaging  
materials are utilized. System boards will be shipped in anti–static bags and (C)MOS devices and  
other sensitive parts in small shielded boxes.  
3.2  
ESD Handling  
In the interest of quality and reliability, it is advisable to observe the following rules when handling  
system boards and parts.  
1. Service personnel should ground themselves by using a wrist strap when exchanging system  
boards in a cabinet.  
2. Keep system boards and sensitive parts in their protective packaging until they are needed.  
3. When returning system boards or parts like EEPROMS to the factory, use the protective  
packaging as described.  
4. Never underestimate the damaging power ESD can have and be especially careful when  
temperatures are below freezing point and during very warm weather in combination with low  
humidity. Make sure that the environmental conditions remain within the limits specified in  
Section 3, "Product Specifications" in this book.

CHAPTER 1  
Introduction  
The DCT1900 system is a pico–cellular, digital cordless telephone system that can be connected to a PBX  
or a Mobility Server via T1 or E1 links or standard analog ports. It is a PWT radio access system, and as  
such enables the user of the Portable Telephone to make and receive telephone calls anywhere in the area  
covered by the system.  
The system consists of a RE connected to the PBX/Mobility Server, several Base Stations and Portable  
Telephones. The coverage is established by means of a pico–cellular network consisting of a number of  
Base Stations connected to the RE. By means of handovers from pico–cell to pico–cell, the user can roam  
within the covered area while maintaining the call without degradation of quality. Built–in voice encryption  
and phone authentication ensures privacy and secure communications.  
All functions that are available on a normal wired analog telephone connected to the PBX are also  
available on the DCT1900 Portable Telephones when connected using an analog or T1 interface. The  
Portable Telephone will provide digital desk set features when connected to the PBX when using the Digital  
Link Unit (DLU).  
The Freeset system is also capable of sending short messages to the portable display using the TAP  
interface to a server running a dedicated software application or a compatible messaging unit.  
The DCT1900 system is based on digital cordless transmissions between the Base Station and the  
Portable Telephone. Speech encoding is done in the RE and Portable Telephone, using 32 kbit/s ADPCM.  
The radio transmissions between the Base Station and Portable Telephone use multiple carrier TDMA. Full  
duplex operation is achieved by using TDD.  
One of the basic features of the system is the decentralized DCA technique, by which each Portable  
Telephone selects the best available speech channel. With DCA, channel selection is not limited to the  
moment of call set–up, but continues during the speech connection. DCA provides for optimum voice  
quality between the Portable Telephone and the Base Station as well as controlling the distribution of  
available channels per Base Station.  
The DCT1900 system can be configured to meet user requirements with respect to the area to be covered  
and the number of Portable Telephones to be used. This system has been designed to operate in indoor/  
outdoor environments and can support both low as well as high traffic density situations.  
In a DCT1900 Standalone environment, the system contains a single RE connected to a PBX.  
In a DCT1900 Mobility environment, the system contains multiple REs connected to the same telephone  
network via a Mobility Server.

CHAPTER 2  
System Overview  
The DCT1900 system may operate as a standalone system or as a mobility system when used in  
conjunction with the Mobility Server. Figures 2-1 and 2-2 show an overview of the environments in which  
the DCT1900 system may be applied.  
The DCT1900 Standalone configuration consists of a single RE and its associated Base Stations con-  
nected to a PBX. In the standalone configuration the RE will connect towards the telephone network with  
either analog type trunks or a T1/E1 channel associated signalling trunk. The DLU provides an intelligent  
interface between the Freeset and a proprietary digital PBX. The DLU emulates a digital phone set of the  
PBX and allows Freeset users to take advantage of digital phone set features. A DCT1900 Standalone  
configuration provides for wireless phone service in a simple and cost efficient manner.  
Digital Phone Set Features  
The DLU supports the following digital phone set features to the Freeset DCT1900 DT620 and  
9p23 Portable Telephones:  
Multiple Line Appearance  
Caller Line Identity  
Connected Line Identity  
Redirected Party Number  
Message Waiting Indication  
Transfer  
Conference  
Hold  
Reconnect  
Call Back  
Cancel Call Back  
The DCT1900 Mobility configuration provides for one or more REs connected to a Mobility Server, which  
will then connect towards the telephone network. Large integrated networks of DCT1900 Portable  
Telephones can be built up using multiple REs and one or more Mobility Servers. The Mobility Server(s)  
provide the capability of intersystem handovers and roaming. In the case of an intersystem handover, a  
Portable Telephone user can be on a call while moving from the radio coverage area of one RE to the radio  
coverage area of another RE without any disruption to the call. In the case of roaming in a DCT1900  
Mobility configuration, a Portable Telephone can originate or accept a call in the radio coverage area of any  
RE. Additional features that the DCT1900 Mobility configuration may support when combined with a  
compatible PBX are Calling Line ID type displays and message indicators.  
DCT1900 features such as phone authentication, encryption, and handover between Base Stations on the  
same RE apply to either the DCT1900 Standalone configuration or the DCT1900 Mobility configuration.  
The signalling interfaces that the RE presents towards the phone network are different in the case of a  
DCT1900 Standalone and a DCT1900 Mobility configuration. Table 2-1 summarizes the signalling  
differences between the two configurations.

Technical Product Manual - DCT1900  
System Description, System Overview  
System Architecture  
The DCT1900 system provides a wireless infrastructure between the user and the MS/PBX. The  
system can serve multiple users at the same time.  
The system can be split up in a fixed part (made up of one RE and multiple Base Stations) and  
many Portable Telephones. The basic configuration of a DCT1900 system allows:  
z
Several systems to provide the same service as one large system. A user with one Portable  
Telephone is able to walk around in different areas covered by different systems without  
interrupting an ongoing call. This feature is known as inter-system handover.  
A user can use the same Portable Telephone in another area or remote site, keeping the same  
number. This feature is known as inter-site roaming.  
z
Different aspects of the DCT1900 system are discussed below.  
Radio Exchange Synchronization (DCT1900 Mobility Configuration only)  
In order to support the inter-system handover capability, REs have to be synchronized. REs are  
synchronized using a master/slave concept, where one master RE supplies a synchronization  
signal to a number of slave REs. A slave RE can act as a master for three further slave REs, thus  
creating a multi level star network with a maximum of two levels, see Figure 2-3.  
Slave  
Slave  
Master  
Level 1

Level 2  
Figure 2-3 Synchronization Topology  
In the master RE, it is possible to select the synchronization source between an internal clock and  
a T1 or E1 interface to the Mobility Server.  
In case the synchronization is lost (e.g. due to cable failure) on a slave RE, the slave will generate  
an alarm on the Mobility interface to notify the MS. However, the slave will continue to operate and

will still synchronize slaves connected to it, effectively forming a separate "sub cluster" within  
which seamless handovers are still possible.  
The delay in the cable used to synchronize the REs must be measured and entered into each of  
the slave REs. The accuracy of this delay measurement is very important and must be taken with  
care.  
Registration  
Registration entails the Portable Telephone establishing a link with the RE/MS, whereby the  
Portable Telephone tells the RE/MS who it is, i.e. extension number, system number range, home  
node number, and the RE/MS authorizes the Portable Telephone to use its resources to make and  
receive calls.  
In the case of a DCT1900 mobility configuration with multiple Mobility Servers:  
z
If the MS is not the Home MS, then there must be a physical connection (QSIG Tie Line)  
between the Home MS and the MS the phone is trying to register to.  
The Portable Telephone’s PUN and authentication key must be known by its’ home MS.  
The system number of the RE must be within the system range initialized in the Portable  
Telephone.  
z
z
Start of Registration  
Registration starts whenever:  
z
The Portable Telephone is switched on and sees a system (within the allowed system range).  
When the Portable Telephone sees a system with better receive signal strength quality than  
the current one which is also in its system range (the Portable Telephone will roam to another  
system).  
z
z
The system asks the Portable Telephone to do so (initiated by the RE/MS). This function  
updates databases which may contain corrupted data (e.g. after restarts of system or RE/MS).  
Note:  
When a Portable Telephone goes out of range and comes back in range of the same RE, the  
registration procedure will not be repeated.  
Registration Successful  
If all requirements are met, the registration will succeed. Note that this dynamic behavior means  
that only at this point will a Portable Telephone be registered in a system. There will never be a  
fixed relation between a system and a PUN!  
Registration Failures  
The registration process may result in a rejection from the RE/MS. If the PUN of the Portable  
Telephone is not initialized in the RE/MS or when the authentication keys in the Portable  
Telephone and RE/MS are different, the Portable Telephone will be rejected. The result will be that  
the Portable Telephone will not try again. Only when the Portable Telephone is switched off and on  
again, or searched by the RE/MS or by the system, will it try to register again.  
The process can also fail because of other reasons. For example, when a connection set–up failed  
or when congestion occurred in a particular Base Station RE/MS, the registration process will  
automatically start again after some time.  
When a Portable Telephone moves from a RE where it was registered to a new RE and the  
registration fails on that new RE, it will still be registered in the RE where it came from.

Technical Product Manual - DCT1900  
System Description, System Overview  
De–registration  
De–registration is the process where the authorization at registration is removed. Once the user is  
de-registered, he can no longer be reached. A user can de–register from the RE by switching the  
Portable Telephone off, or by roaming to another system.  
Whenever the RE is not able to inform the MS (e.g. congestion in the MS) about the de-  
registration, the RE will repeat it every time there is an incoming call for that specific Portable  
Telephone.  
Authentication  
The authentication of a Portable Telephone is done during registration and at incoming or outgoing  
call establishment. It will be executed according to the PWT Standard Authentication Algorithm  
(PSAA). The algorithm uses the authentication key that is downloaded over the programming  
cable into the Portable Telephone during initialization.  
In a DCT1900 Mobility Server configuration for performance reasons, a session key (temporary  
key, reissued at registration time) will be stored locally in the RE as the result of a registration, to  
allow authentication without consulting the MS during call establishment.  
Inter System Handover (DCT1900 Mobility Configuration Only)  
Inter system handover is the capability in a mobility configuration of a Portable Telephone that is  
handed over automatically to another RE when leaving the coverage area of one RE and moving  
into a coverage area of another RE. When a user moves to a new RE (refer to Figure 2–2), on  
request of the MS the old RE will remove the relation between the moved Portable Telephone and  
the old RE (de–registration) while the new RE adds the relation between it and the Portable  
Telephone (registration). Handovers from one RE to another can only be achieved when all of the  
following conditions apply:  
z
z
z
z
Base Stations of different RE’s meet the PWT specifications.  
The REs involved are synchronized.  
Both REs have system numbers that fall within the Portable Telephone system range.  
The Portable Telephone detects a stronger signal from the new RE than the old RE.  
If these conditions are not met, the inter system handover will not be seamless or the call can even  
be lost when the Portable Telephone tries to move to the new RE.  
If two REs operate in overlapping areas, a Portable Telephone may need to choose between an  
intra system (to another Base Station of the same RE) and an inter system handover. In these  
situations, the Portable Telephone will prefer an intra system handover. In general, a 6dB signal  
strength improvement is required for an intra system handover while a 12dB improvement is  
required for an inter system handover.  
Roaming (DCT1900 Mobility Configuration Only)  
Roaming is a feature whereby a Portable Telephone moves between two geographically separate  
but electronically connected MSs with the attendant REs. When turned on in its home coverage  
area, the Portable Telephones’ connectivity and functionality is normal. When turned on in the  
other MS coverage area, the Portable Telephone registers itself as a visitor and this MS  
communicates with the other MS to let it know that the Portable Telephone is now active on the  
other RE. Any calls to the Portable’s PUN will then be routed to the new MS to be passed on to the  
Portable Telephone.

2.2  
Roaming and Handover Handling by the Portable Telephone  
Sections 2.2.1 and 2.2.2 describe when the Portable Telephone starts internal (intra cell, same  
Base Station), external (inter cell, another Base Station of the same RE) and inter system  
handovers (another Base Station of another RE) and location updates (roaming).  
2.2.1 Unlocked Situation  
When the Portable Telephone is first turned on, it will regularly scan the air interface. As soon as  
the Portable Telephone detects a bearer signal from a Base Station, it will lock to this bearer. A  
bearer is an active PWT air interface channel in which transmissions take place. When a Base  
Station is idle (there are no calls routed via this Base Station), it transmits a dummy bearer which is  
also referred to as a beacon signal. Dummy bearers enable the Portable Telephone to lock on to  
an idle Base Station and to scan the environment.  
If the synchronizing system number is not part of one of the Portable Telephone subscriptions, the  
Portable Telephone will scan the air interface again.  
If the synchronizing system number is part of the system range of one of the Portable Telephone  
subscriptions, that subscription will be selected and the Portable Telephone will use the bearer as  
a standby bearer. From this moment on the Portable Telephone will start to collect data  
concerning the situation in other channels on the air interface. This synchronous situation is  
described in the paragraphs below.  
The Portable Telephone falls back to asynchronous roaming if during a certain period of time no  
valid frames are received. In this case all collected data concerning the situation in other channels  
is cleared.  
To limit the energy consumption during the unlocked situation, the Portable Telephone will go into  
a sleep mode if it does not find a bearer within 10 minutes. The sleep mode will be interrupted  
every 2 minutes, when the Portable Telephone performs one full scan to see if there are any  
systems present.  
2.2.2 Locked Situation  
Environment Scanning by the Portable Telephone  
If the Portable Telephone is locked to a standby bearer, it maintains a list of information for each  
channel on the air interface. This is called a history list, which contains the following information:  
RSSI:  
For each channel, a received "Received Signal Strength  
Indication" (RSSI) value is stored. For an active bearer, this is an  
indication of the strength of the received signal. For an idle  
channel, this is an indication of the noise level.  
RQI:  
For each channel with an active bearer or dummy bearer, a  
"Received Quality Indication" (RQI) value is stored. The RQI  
value is determined by the number of correctly/incorrectly  
received frames.  
Base Station & System ID:  
For each channel with an active bearer, the Portable Telephone  
will store the identification of the Base Station and RE.

System Description, System Overview  
System Status  
A Portable Telephone contains a list of the current RE status. For each system, the status may be:  
NOT_ALLOWED:  
TEMP_NOT_ALLOWED:  
The Portable Telephone is not allowed to access this RE.  
The Portable Telephone is currently not allowed to access this  
RE, but may be allowed to access this RE in the future.  
The Portable Telephone is allowed to access this RE.  
ALLOWED:  
Roaming  
If the Portable Telephone is locked to a certain Base Station, two types of roaming are supported:  
voluntary roaming, when a better bearer is available, or forced roaming, when the current bearer is  
no longer valid. If the Portable Telephone is locked to a RE, it regularly scans its environment.  
During the environment scan alternative REs are investigated and a bearer set–up may be  
attempted.  
Voluntary Intra System Roaming  
Voluntary intra system roaming takes place if the Portable Telephone detects a Base Station of  
which the signal strength is at least 6dB stronger than the current bearer, and remains at least this  
amount stronger during a number of consecutive frames.  
Voluntary Inter System Roaming  
Voluntary inter system roaming takes place when:  
z
The RE status of the other RE is higher than the system status of the current RE. If the RE  
status of the other RE is higher than the RE status of the current RE during a number of  
consecutive frames, a location update will be started.  
z
The RE status of the other RE is equal to the RE status of the current RE. If the RE status of  
the other RE is equal to the RE status of the current RE and the RSSI is at least 12dB stronger  
than the current bearer RSSI during a number of consecutive frames, a location update will be  
started.  
z
The RE status of the other RE is lower than the RE status of the current RE. If, during a  
number of consecutive frames, the RE status of the other RE is lower than the RE status of the  
current RE and the RSSI of the best bearer of a Base Station of the other RE is at least 12dB  
stronger and the Portable Telephone does not see any other Base Stations of this RE and the  
current Base Station has no further bearers available, the Portable Telephone will start a  
location update.  
Forced Intra System Roaming  
If the current bearer cannot be used any more, the Portable Telephone will immediately try to  
switch to the best bearer on the current RE.  
Forced Inter System Roaming  
If the bearers of the current RE cannot be used any more, the Portable Telephone will immediately  
try to switch to the best bearer of alternative REs.  
Handover  
During a call, two types of handover are supported again: voluntary handover and forced  
handover. If there are no problems with the current bearer, the Portable Telephone will investigate  
alternative bearers during a call. Handling of the forced handover is critical because in this case  
the speech service is disrupted.

Technical Product Manual - DCT1900  
Voluntary Intra System Handover  
If the best bearer of another Base Station is at least 6dB or better during a number of consecutive  
frames, the Portable Telephone will start a handover to that Base Station.  
Voluntary Inter System Handover  
For handovers, only REs with the RE status ALLOWED and TEMP_NOT_ALLOWED are  
considered as alternatives:  
z
The RE status of the other RE is equal to the RE status of the current RE. If the best bearer of  
a Base Station of another RE is at least 12dB or better during a number of consecutive frames  
and there is a bearer free on this Base Station, an inter RE handover will be started.  
The system status of the other system is lower than the system status of the current system. If,  
during a number of consecutive frames, the RE status of the other RE is lower than the RE  
status of the current RE, and the best bearer of a Base Station of the other RE is at least 12dB  
better and of the current RE no other Base Station is detected and the current Base Station  
has no other bearers available, then a location update will be started.  
z
Forced Intra System Handover  
If the quality of the traffic bearer becomes unacceptably bad, an immediate attempt to find a  
different bearer is started. This may result in a handover.  
Forced Inter System Handover  
If a good bearer cannot be found within the current RE, alternative systems will be investigated in  
the history list. If no RE is found, the Portable Telephone quickly scans its environment to find a  
valid bearer. If a bearer is found and the network has not yet cleared the call, the Portable  
Telephone continues to scan its environment. If the network has cleared the call, e.g. because the  
search took too long, the Portable Telephone will release the call.  
2.3  
User Functions  
The user functions are depending on type of interface between the RE and the connected  
Telephone Network, and the features supported by the connected Telephone Network.  
2.3.1 DCT1900 Mobility Configuration and E1-CAS Standalone when  
connected to a MD110  
Calling Party Number (ID)  
Calling party number is the extension number shown to the user on a Portable Telephone display  
upon receipt of an incoming call and used to identify who is calling. The maximum length equals  
24 digits.  
Connected Party Number  
This feature will enable the PBX to inform the user of the party to which it is connected. The  
maximum length is 24 digits. The message can be expected at outgoing call set–up or whenever  
the other party changes.  
Redirecting Party Number  
The same as connected party number, except that it will only be sent when the call is diverted  
towards another extension. The maximum length is 24 digits.

Radio Exchange  
The RE interfaces between the PBX/MS and the Base Stations. Incoming and outgoing calls are  
routed via the RE.  
The RE may be connected to the PBX via an E1 connection, T1 connection, standard analog two–  
wire lines or possibly a digital interface. The RE may connect to the MS via an E1 or T1 CCS  
interface.  
Standard RS232 ports on the cabinet make it possible to connect a personal computer and a  
printer or a SMS server (in SA mode) to the system. The personal computer is necessary for  
system initialization, system fault tracing, system statistics information retrieval, and Short

Message Service (SMS) source. The printer can print a hardcopy of the system error messages.  
In a multiple system configuration, up to 13 RE’s can be cascaded together.  
The RE consists of:  
z
–One to four Modular Cabinets. The 10 inch Modular Cabinet contain a MCCB and a  
backplane with 9 system board connectors, a rectifier circuit and a DC/DC converter.  
–A number of system boards.  
z
The Modular Cabinet requires an external power source of -48Vdc.  
3.2  
Base Stations  
The Base Station enables radio communications between the RE and Portable Telephones.  
The Base Station has two main functions:  
z
To modulate a carrier with the digital encoded information (TDMA frame directed to Portable  
Telephone),  
z
To demodulate a modulated carrier (TDMA frame received from Portable Telephone).  
A Base Station communicates with the RE via two (2B+D) interfaces, requiring two twisted pair  
cables. The two 2B channels (256 kbit/s) provide eight 32 kbit/s speech paths between a Base  
Station and a RE, enabling a Base Station to handle eight simultaneous calls. In addition to data  
communication, these two twisted pairs are also used to distribute power to the Base Stations.  
One or two additional pairs can be wired to provide a longer powering distance.  
Two methods exist to power Base Stations:  
z
Via local power supply.  
Via Modular Cabinet.  
z
With the first method, Base Stations are powered by -48Vdc which is not routed via the cabinet.  
The maximum cable length between Base Station and RE is only data limited and may reach up to  
11,500 ft.  
With the second method, power is distributed via the Modular Cabinet and Base Station cabling.  
The cable length between the Base Station and cabinets now depends on the number of twisted  
pairs used for power, the type of cable and environmental noise.  
The number of Base Stations used in a system depends on the area to be covered and the traffic  
density. Typical in–house coverage is a 100-200 ft. radius. The cell size may vary between 40 ft.  
indoors and up to 1,000 ft. outdoors.  
The air interface conforms to PWT MAC Layer and FCC part 15.  
3.3  
Portable Telephones  
The Portable Telephone (PT) supports the basic functions of a normal wired DTMF–type  
telephone. The PT is available in three models: the 9p23, the DT600 and the DT620. Each is  
equipped with a 3-line 12 character dot matrix LCD display, backlit illumination keypad and display,  
and plastic keypad. See Section 3, "Product Specifications," Chapter 1, "Portable Telephones"  
and Chapter 12, "Portable Telephone Accessories" for further information. With the DLU, the 9p23  
and DT620 PT will support up to 4 line appearances.

Digital Trunk Unit - DTU-E1  
4.6.1 CCS - REX-BRD0003 or 2/ROFNB 157 13/6  
The DTU provides the digital interface between the MS and the RE. The physical connection with  
the MS is established via twisted pair cables.  
Every DTU board contains 2 DTCs (see Figure 4-4), each equipped with identical firmware. Both  
DTCs support the Common Channel Signalling (CCS) interface.  
Each CCS interface provides 30 (total 60 per board), communication channels to which Portable  
Telephones are assigned dynamically. These channels are shared by the Portable Telephones  
which means that although the RE can handle more Portable Telephones, only 30 calls per CCS  
interface can take place at the same time. The maximum number of Portable Telephones a RE can  
handle depends on the GOS (grade of service) and the traffic capacity of the RE configuration.  
However, there is a maximum of 60 concurrent off hooks and a maximum of 1 DTU-E1 card per  
mobility RE.

CHAPTER 5  
Other System Aspects  
5.1  
Installation and Maintenance  
As each DCT1900 system is configured to meet specific user requirements, the RE must be  
assembled on location. The system must be initialized after the physical installation. DCT1900  
system initialization, maintenance and updating, and fault finding and repair are accomplished with  
the aid of the CSMW Software program running on a personal computer.  
Automatic System Maintenance is a built–in feature that will detect, report, isolate, and when  
possible, recover the system from errors.  
All of the system boards in the RE have a number of light emitting diodes that enable maintenance  
personnel to quickly localize a faulty board. This feature is applicable during the power–up phase  
and operational use of the system.  
5.2  
5.3  
Statistics  
The CSMW software is capable of collecting statistical information. During operational use of the  
DCT1900 system, useful information can be registered. This information can consist of the total  
call time of all Portable Telephones per hour during a day or a period of days, highest number of  
simultaneous calls, call duration per user, distribution of calls according to the call length, load of  
Base Stations, status information of a call, handovers, etc. All this information is useful to analyze  
the performance of the DCT1900 system.

System Description, Other System Aspects  
Base Station Numbering  
Base Stations are identified by hexadecimal numbers 08-FF which are referred to as Base Station  
numbers or Base Station identities. A range of eight hexadecimal numbers is assigned to the  
CLCs of a SLU/CLU when you add the first Base Station to it by means of the CSM software  
command Base Station–Add. When you add the first Base Station to another SLU/CLU the next  
free eight hexadecimal numbers are assigned to its CLCs. The first SLU/CLU receives 08-0F, the  
next SLU/CLU that has a Base Station added will be 10-17. The Base Station assigns Base  
Station numbers according to the CLC it is physically connected to. CLC 1 correlates to Base  
Station number 08, or 10, etc.  
The hexadecimal numbers 00 to 07 are not used. Therefore the hexadecimal numbers 08 to 0F  
will be assigned to the first SLU/CLU used to add the first Base Station. Base Station numbering is  
08-FF.  
Given below is an example:  
1. When you define the first Base Station of the first SLU/CLU, its CLCs (1 to 8) will get Base  
Station numbers 08 to 0F (hexadecimal).  
2. When you define the first Base Station of the second SLU/CLU, its CLCs (1 to 8) will get Base  
Station numbers 10 to 17 (hexadecimal).  
3. When you define the first Base Station of the third SLU/CLU, its CLCs (1 to 8) will get Base  
Station numbers 18 to 1F, etc.  
If a SLU/CLU board is removed by the CSMW "Remove Board" command, a gap of 8 Base Station  
numbers may arise. When there is a gap in the numbering, and the first Base station is added to  
another SLU/CLU, the numbering system described above is used; the numbers in the gap are not  
used. If in such a situation all Base Station numbers are used (08 – FF), the Base Station numbers  
of the oldest ”gap” are used.  
Note that if there are gaps in the Base Station numbers, the Base Station numbers will shift after a  
system reset. If, for example, the second SLU/CLU is removed, then after a system reset the  
numbers are:  
z
The CLCs of the first SLU/CLU still have Base Station numbers 08 to 0F  
z
The CLCs of the third SLU/CLU now have Base Station numbers 10 to 17, etc.

CHAPTER 1  
Introduction  
The DCT1900 system was developed as a modular system in order to obtain maximum flexibility  
in initial configuration and future growth. Each system can be configured to satisfy the specific  
customer requirements.  
The Configuration Directions provide an explanation of the different factors that influence the size  
of a system and their acceptable values. Restricting limitations are also discussed. The factors  
that determine the final configuration of a system are:  
z
z
z
number of Base Stations  
number of Portable Telephones in the coverage area  
traffic requirements for the system  
Furthermore, the system has a number of restrictions that give limitations to the configuration.  
These items are explained in the following chapters.  
To determine a system configuration, the limitations of the system must be known first. These are  
described in Chapter 2.  
The number of Base Stations determine the number of CLCs to be used. The number of CLCs,  
together with the cable lengths, define the power requirements for the power supply and the  
number of SLUs and/or CLUs to be used. The required number of Base Stations can be found by  
doing a site survey. Site Surveys and Base Station powering are discussed in Chapters 3 and 4.  
The traffic requirements for a system are determined by the amount of Portable Telephones in the  
coverage area (visiting Portable Telephones included), the estimated traffic generated per  
Portable Telephone and the GOS accepted by the customer. These figures define the number of  
SPUs required. Traffic requirements are explained in Chapter 5.  
When the number of each system board type needed in a system is known, the number of  
cabinets, power supplies, internal cables, etc. can be calculated. The relationships between all  
these parts are outlined in Chapter 6.

Configuration Directions, Limitations of the System  
CHAPTER 2  
Limitations of the System  
2.1  
Modular Cabinets  
Cabinet  
A system can support up to 4 cabinets. Each cabinet provides space for a combination of 9  
system boards. This means that the total size of the system may be 36 system boards. All boards,  
except for the CPU which is always placed in cabinet 1, can in principle be placed in any slot.  
However, due to the MCCB layout and power limitations not all combinations are allowed.  
Powering limitations of the Modular Cabinet are discussed in paragraph 2.2.  
Connection Board  
A Modular Cabinet has only one MCCB which is factory fitted. The MCCB provides Base Station  
power connections for a total of 7 CLU and/or SLU boards.  
Power Supply  
Modular Cabinets are powered by an external -48Vdc supply. Base Stations may be powered by  
the same power supply or by a second external power supply connected to the MCCB.  
Base Stations  
The number of Base Stations is limited to 120. A number of Base Stations can be powered via a  
single cabinet as mentioned above. Furthermore, the external power source specifications can  
limit the maximum number of Base Stations.  
Number of Portable Telephones  
The number of Portable Telephones that can be supported by the Standalone DCT1900 system is  
600 when digital trunks (DTUs) are used, 144 when digital links (DLUs) are used and 208 Portable  
Telephones when analog lines (LTUs) are used. The number of Portable Telephones supported by  
the DCT1900 Mobility System controlled by the MS but cannot exceed 2048 for a single RE.  
CPU Firmware  
The memory space reserved by the CPU for each type of board is limited to a maximum of 15 CLU  
boards, 8 SPU/SLU, 34 LTU, 10 DTU-E1 , 34 DLU and 13 DTU-T1.  
Cabling  
When the cable length is only data limited, Base Stations may be connected up to a distance of 2.2  
miles away from the REs when using a CLU board, or 1.3 miles when using a SLU/CLU-S board.  
In case the cable length is power limited, the distance depends on the powering method that is  
used (see Chapter 4).  
For the DTU E1 card, in case a cable other than the Ericsson supplied cable is used between the  
RE and the PBX to cover a longer distance, this cable should not attenuate more than 6dB at  
1.024 MHz (e.g. a cable with an attenuation of 2 dB/100 m at 1.024 MHz gives a maximum  
distance of 328 yards). The maximum length of 100 ohm cable used to connect the DTU-T1 to a  
PBX/Centrex is 666 ft.  
All twisted pair cables are shielded signal cables and the shield must be tied to ground by using  
the ground strip at the bottom of the cabinet. This ground strip provides cable connections for any  
combination of up to 8 twisted pair shielded cable sets.

Synchronization Distribution (DCT1900 Mobility Configuration Only)  
A DCT1900 system can provide synchronization to three other DCT1900 systems if it is the  
synchronization master or is connected to a synchronization master (only two levels are allowed,  
see also Figure 2–1). If PWT air interface (frame) synchronization is required between DCT1900  
systems, then the DCT1900 systems have to be connected to each other by means of an external  
sync cable. The maximum external sync cable length is .8 mile (this value depends on the core  
diameter of the cable, refer to Chapter 18, Paragraph 18.2 of the Installation Instructions for more  
details).

2.2  
Modular Cabinet Powering Restrictions  
Although the Modular Cabinet has space for 9 boards, not all board combinations are allowed due  
to power limitations of the DC/DC converter on the backplane. This converter is specified as  
follows:  
+5 V  
+12 V  
-12 V  
total  
can supply 40 W at maximum  
can supply 12 W at maximum  
can supply 12 W at maximum  
must be <40 W  
Table 2–1 shows the power consumption per board type. From this table, it can be calculated if a  
configuration matches the power requirements. The values given to the 12V of the LTU indicates  
the power consumption in the case where all LTU circuits are off hooks.  
Note:  
Due to a minimum required power consumption from the DC/DC converter, at least two boards  
must be present in each cabinet.

CHAPTER 3  
Base Station Planning  
The major task in configuring a DCT1900 system is defining the number of Base Stations required  
to cover an area to a satisfactory level. This Chapter describes how a Base Station plan can be  
made in order to gain full area coverage. Chapter 5, Paragraph 5.2 explains how traffic  
requirements additionally influence the number of Base Stations.  
Another aspect of Base Station configuration is powering of Base Stations. The various ways of  
distributing power to the Base Stations and the requirements on the power supply are described in  
Chapter 4.  
3.1  
Introduction  
The radio environment or the cell that is covered by a Base Station is not a spherical shape as  
often suggested in drawings. If a snapshot could be taken of the cell, it would become clear that its  
shape is more of a cloud form. The momentary size and shape vary depending on the material of  
which walls and floors are made of, the position and material of furniture, machines, air–  
conditioning and the position of the Base Station in such an environment. Because of these  
unpredictable conditions it is not possible to give any hard rules for calculating the number of Base  
Stations in a given situation.  
Base Station planning is not very difficult. However, size, architecture and the structure of  
buildings and their influence on the RF field pattern cannot be foreseen. The quickest and simplest  
way to do the Base Station Plan is by measuring. During a site survey, an average cell size can be  
determined, with the help of a Site Survey Tool. This forms the basis of Base Station planning.  
Experience is the best guide in making a Base Station plan.  
The guide–lines listed below will help give a better view on the local situation when the placement  
of Base Stations is being planned. Paragraph 3.6 explains how a site survey can be done.  
3.2  
Total Area Coverage  
z
z
The in–house cell size in offices may be in a range of 30-200 ft. radius; see Figure 3–1.  
The cell size in exhibition halls or production halls may go up to a 660 ft. radius when there is  
enough free space for radio signals to travel.  
z
z
The cell size outdoors in free space may be up to 1000+ ft. radius.  
Base Stations should not be placed near the outer walls of the building as this reduces the  
effective coverage area, except of course when a parking area, for example, has to be  
covered.  
z
Base Stations may partially cover the floors immediately above and below as well. The useful  
range through floors and ceiling varies between a 0 and 26 ft. (2 floors) radius; see Figure 3–1.  
3.3  
Absorption and Reflection  
z
z
The cell size depends on the materials used in walls, ceilings and floors.  
Plain, light or reinforced concrete, wood and plaster all absorb and pass radio waves in  
different ways.  
z
Metal walls and large metal cabinet rows reflect all signals, resulting in greatly reduced  
coverage behind these areas.

z
z
X–ray rooms in hospitals protected by lead walls, computer rooms in banking buildings  
protected against unwanted interference, etc. do not allow radio signals to enter.  
Exhibition halls or production halls may give reflections due to huge metal structures. This  
causes interference which reduces the capacity and coverage area per Base Station.  
3.4  
3.5  
Departmental Differences  
z
More traffic is generated in sales, purchasing, technical support departments, cafeterias, etc.  
than finance & administration or research & development. Consequently, a higher traffic  
capacity is needed in these areas requiring additional Base Stations to be installed. More  
details follow in Chapter 5.  
Architecture  
z
Central areas giving access to stairs and elevators may require extra Base Stations due to  
heavier constructions.  
z
z
Coverage in elevators may require Base Stations closer to or in the elevator shaft.  
Corners and irregularities in the construction (partial renovation, extensions of older buildings  
etc.) have an influence.  
z
Concentration of air–conditioning ducts, etc. may influence the coverage.

3.6  
Site Survey  
To satisfy area coverage and traffic demands, the site must be surveyed in order to determine the  
number and position of Base Stations. To do a site survey, a site survey tool and floor plans of the  
building are required. With the help of these tools proper Base Station planning can be done.  
Samples must be taken to determine an average cell size. With the average cell size, Base Station  
positions can be indicated on the map together with the area covered by each Base Station.  
Difficult spots can be mapped as well. After this, the planned positions can be verified with the site  
survey tool and with the help of the traffic requirements, a final plan can be made.  
When doing the survey with the Site Survey Tool, read the instructions below:  
1. Observe the building to find a "typical area"  
Modern buildings usually have standard constructions. In older buildings, due to renovations  
or expansions, areas with different structures may exist. However, inside these areas a  
uniformity in structure can be found again.  
Find an area with a typical structure for the building and of about the expected cell size. This  
area will be used to determine the typical cell size. With a building with different structures, find  
the cell size of each of those areas, so that differences in "typical cell size" can be detected.  
2. Measure the horizontal cell size on the middle floor, see Figure 3–2, (1)  
The cell size is measured by setting up a call with a portable and listening to the speech  
quality. This test is more accurate, faster and easier to use than the RQI indicator of the  
Portable Telephone’s DCS. See Section 6, "Commissioning" in this manual.  
The cell size can be determined as follows:  
-
-
-
Install a Base Station in the middle of the "typical area" and power the Site Survey Tool.  
Switch a Portable Telephone to DCA mode and set up a call.  
Walk away from the Base Station in one direction. Also enter rooms with the Portable  
Telephone switching to your left and right hand.  
-
The edge of the cell is found as soon as crackling sounds and/or mutes appear. Step back  
to where no mutes or sounds were heard. Verify whether the RQI remains stable on 20  
and measure the distance to the Base Station. Within a cell, no mutes or clicks should be  
heard and the RQI should be stable on value 20.  
-
-
Do the same in the opposite direction.  
The two distances should be about the same. This is the horizontal coverage on the floor  
of the Base Station.  
3. Measure horizontal range on floor above, see Figure 3–2, (2)  
Go to the floor above, leaving the Base Station on its current location and measure the  
horizontal coverage here.

Technical Product Manual - DCT1900  
4. Measure horizontal range on floor below, see Figure 3–2, (3).  
Go to the floor below, leaving the Base Station on its current location and measure the  
horizontal coverage again.  
Note:  
If the building is quite transparent to radio signals, the vertical coverage can reach to another floor  
above and below.  
In this way the horizontal and vertical coverage of a single Base Station in a typical area is found.  
The cell size found can be taken as an average and used to calculate the total number of Base  
Stations. From Figure 3–2 it is clear that three Base Stations can cover a building as seen in  
Figure 3–1.  
Depending on the size of the building and the type of construction, one or two more "random  
checks" in typical areas can be done to verify the first measurement. The typical cell size is then  
found by averaging the values.

5. Making a plan  
-
With the "typical cell size" found, make a sketch of all Base Station positions on the floor  
plan. Indicate the expected coverage for each Base Station on the map.  
Verify with the Site Survey Tool if the real coverage is as expected from the map.  
Especially verify coverage in difficult areas such as elevators, stairways and  
discontinuities in construction.  
-
-
-
-
If weak areas are found, see if re–positioning of Base Stations solves it; otherwise, plan an  
extra base station.  
Take into consideration that in free space, with antennas in upright position, the coverage  
is horizontal more than vertical. Although in normal office environments this effect is  
negligible due to the amount of reflections, it still may be worth trying to place Base  
Stations horizontally in order to get more vertical coverage such as in stairways.

6. Finalizing the plan  
-
When all Base Station positions on the map are verified and the plan is in place, discuss  
with the parties concerned whether, due to local traffic requirements, (see Chapter 5,  
Section 5.2), extra Base Stations are needed in particular areas. Integrate these Base  
Stations with the plan.  
Thus a final Base Station plan is made and tested simultaneously.

CHAPTER 4  
Base Station Powering  
4.1  
General  
After a Base Station plan has been made (see Chapter 3), it must be established which powering  
method is more suitable to power the Base Stations. The methods for powering a Base Station are:  
z
Via the RE  
z
By a remote power supply  
The choice of the method depends upon:  
z
z
z
z
The distance between the RE and the Base Stations  
The total number of Base Stations  
Whether power back–up is needed or not  
Installation costs  
Paragraph 4.2 describes the powering of Base Stations by means of a remote power supply.  
Paragraph 4.3 describes the powering options for the Modular Cabinet. The tables used in this  
chapter are given in Paragraph 4.4.  
The length limits for the Base Station cable are described below.  
Data Limited Length of the Base Station Cable  
Data transmission via twisted pairs is limited to a certain range. The "data limited" length of the  
cables between the RE and the Base Stations depends on the system board used (CLU or SLU),  
the characteristics of the cable, and the noise on the cable. Table 4–1 shows the data limited  
length for some cables.  
Note:  
Since it is not possible to predict the noise level in an environment and its influence on a cable, the  
values from the table should be taken as a guide-line more than a rule. Practically, the maximum  
length may exceed these values, in case there is less noise and vice versa if there is more noise.  
Power Limited Length of Base Station Cable  
When a Base Station is powered via the cabinet, the maximum length between the Base Station  
and the RE depends on the supply voltage, the number of twisted pairs used and the wire size.  
The length of the cable should never exceed the "data–limited" length of the cable.  
4.2  
Powering Base Stations by a Remote Power Supply  
When Base Stations are powered by a remote power supply, only a cable with two twisted pairs is  
required between a Base Station and the RE for data transfer (see Figure 4–1).  
Powering Base Stations with a remote power supply can be done by using the EPP pins on the  
Base Station connector. Base Stations can be powered individually or in clusters from a central  
power source. A cluster can be e.g. Base Stations on the same floor or in the same building,  
assuming that Base Stations within the cluster are close enough to the remote power supply. The  
length of the cable between the Base Station and the RE is "data limited". See Table 4-1 for the  
maximum cable length.

Powering Base Stations via the Modular Cabinet  
Base Stations are powered via the following path:  
External source-MCCB-CLU/SLU-Base Station  
z
Base Stations are connected to the CLU or SLU via an MDF by 2, 3 or 4 twisted pair cables. The  
maximum permissible length depends on the wire size and the number of pairs used between the  
MDF and Base Station. The CLU/MDF cable contains only one Express Powering Pair (EPP), but  
this may be doubled up on the MDF. Table 4–2 shows the maximum cable lengths.  
4.3.1 –48V External Source Powering  
Via an external -48V source, any configuration of cabinets and Base Stations can be powered as  
long as the power specifications of the external source are met. This method is suitable for any  
situation where PBX power is available (see Figure 4–2) or any other -48V supply with sufficient  
current capacity. The maximum cable lengths are given in Table 4–2 (42V and 48V column).

Technical Product Manual - DCT1900  
Note:  
When using the PBX option refer to the PBX supplier and/or PBX documentation to assure that the  
PBX power supply matches the worst case power requirements of the DCT1900 system.  
The external source must supply –48Vdc, which may be connected to the backplane for powering  
the system boards and directly to the MCCB for powering the Base Stations. Each cabinet uses 50  
Watts maximum to power the Boards.  
Tables 4-3 and 4-4 can be used to calculate the power requirements for the Base Stations. Table  
4-3 has to be used when a battery back–up is used. Table 4-4 has to be used when no battery  
back–up is used. The alternative method described in Paragraph 4.5 can be used as well.  
The number of Base Stations powered per Modular Cabinet is limited by the MCCB which can  
connect up to a total of 7 CLUs and SLUs to distribute Base Station power.

Alternative for Calculating the Power Consumption per Base Station  
In Figure 4–4 the power consumption of the Base Station and the cabling is given as a function of  
the cable length in terms of percentage. This relation is almost independent of the number of cable  
pairs, cable resistance and supply voltage. Table 4–5 also gives this relation in steps of 5 percent.  
The table can be used as follows.

number of EPP (Express Powering Pairs) : 0  
wire size  
length  
: 24 AWG (R =0.055 /m)  
tp  
: 820 ft.  
With this information the maximum cable length can be read from Table 4–2. The maximum length  
can also be calculated using the formulas in Paragraph 4.4. When using these formulas, you must  
use n=2 for the number of pairs (2 data pairs, no express powering pairs). With both methods the  
result is 2763ft.  
The length of the cable is (820/2763) 100%+29.7% of the maximum cable length. Round up this  
value (30%) and read the dissipated power from Table 4–5. The dissipated power is 8.3W.

Configuration Directions, Traffic Capacity of the System  
CHAPTER 5  
Traffic Capacity of the System  
The traffic capacity of the DCT1900 system is mainly determined by the RE and in exceptional  
cases also by the Base Stations. The RE can handle a maximum of 60 simultaneous calls, and a  
single Base Station has a capacity of 8 simultaneous calls.  
5.1  
Traffic Capacity of the Radio Exchange  
The traffic capacity of the RE is determined by:  
z
z
z
Total traffic (Erlang)  
The GOS accepted by the customer.  
The number of speech circuits available, with a limit of 60.  
Erlang is a measurement of telphone traffic. One Erlang is equal to one full hour of use, or 60 x 60  
= 3,600 seconds of phone conversation. You convert CCS (hundred call seconds) into Erlangs by  
dividing by 36.  
The GOS is the probability that a call cannot be made because of congestion in the system. The  
customer has to indicate which GOS is acceptable. A GOS of 1%, or 0.01, means an average of 1  
blocked call in every 100 calls.  
SPU and SLU boards provide for 8 speech circuits. When a total of 8 SPU and SLU boards are  
installed, then 64 circuits are available, of which only 60 can be used simultaneously, as the  
DCT1900 system can handle only a maximum of 60 simultaneous calls.  
The two parameters mentioned above (GOS and number of speech circuits) and the total amount  
of traffic (Erlang) that is required are related to each other. Table 5–1 below shows how these  
parameters are related for certain values. This table is used to calculate from a given GOS and  
Erlang value the number of SPUs/SLUs needed. The Erlang value is the total traffic generated by  
all Portable Telephone users (including visiting Portable Telephone users) in the coverage area of  
the system.

Configuration Directions, Traffic Capacity of the System  
As a RE can handle only as many simultaneous calls as the number of available speech circuits  
while the number of Portable Telephones in the respective coverage area can be as many as 600,  
a lack of speech circuits may occur in some occasions. To limit these occurrences, take into  
account the number of regular (home) Portable Telephone users plus the maximum number of  
visiting Portable Telephone users at a certain time while determining the required traffic capacity.  
Table 5–2 shows what Erlang values mean in call–minutes for a Portable Telephone.

Table 5–2 Erlang Values Expressed in Call–Minutes  
Example: A customer ordering a system that can handle 55 Portable Telephones (local users  
and visiting users), generating 200 mE each in average, requires a system with a  
traffic capacity of 11 E. With an accepted GOS of 0.5% the number of SPUs/SLUs is  
found as follows:  
The total traffic is 11 E. In the column of 0.5% GOS, the next higher value of 11 E is  
14.2 E, resulting in 3 SPUs/SLUs.  
So, the system should be equipped with 3 SPUs/SLUs, offering the client 14.2 E  
instead of 11. This means that the system has an over–capacity 3.2 E, which allows  
expansion of the system with 16 Portable Telephones without reducing the GOS or the  
need of more SPUs or SLUs.  
According to Table 5–1 60 circuits with an accepted GOS of 0.5% result in a maximum traffic  
capacity of the system of 44.8 E. When each Portable Telephone generates 150 mE in average,  
the system has a capacity of serving approximately 300 Portable Telephones.  
5.2  
Traffic Capacity of the Base Stations  
The total traffic that is being generated by all Portable Telephones (visiting Portable Telephones  
included) of the system should be in accordance with the capacity of the cordless network as well.  
A Base Station, having 8 channels available, has an Erlang value of 2.7 with a GOS of 0.5%. This  
value can be read from the Table 5-1. This means that each Base Station can serve 18 Portable  
Telephones, assuming that Portable Telephones generate 150 mE each during busy hours (13.5  
Portable Telephones if 200 mE each).  
Example: Suppose that in the building of the customer in the example in paragraph 5.1, full  
coverage can be achieved by 4 Base Stations. This means that all Portable  
Telephones generate together 55 x 0.200 = 11 E, while the Base Stations traffic  
capacity is only 4 x 2.7 = 10.8 Erlang. This is too little. This discrepancy can be solved  
by adding another Base Station near the busiest part of the building.  
From an average point of view, the total capacity offered by the cordless network is generally more  
than sufficient. In certain places, traffic demands may vary such that locally the network is often  
blocking, or has a lower GOS than required. For instance, a purchasing department may easily  
generate 300 mE per Portable Telephone during a busy hour, with 6 persons giving a very high

load on the Base Station close by. It may be necessary to add a Base Station in this area to have  
enough capacity for others to call as well.  
5.3  
Traffic Capacity of the System  
The traffic capacity limitations of both the RE and the cordless network are discussed on the  
previous page. A user making calls will first face a blocking chance by the cordless network and  
then face another blocking chance by the system. These two parameters are statistically  
independent and should therefore be summed to find the overall blocking probability of the  
system.  
When an overall GOS of 0.5% is required, the system must be configured such that the GOS of  
the RE summed with the GOS of the network together result in a GOS of 0.5%.

Installation Area for the Modular Cabinet(s)  
z
Do not mount the cabinet to drywall using plastic drywall plugs. Recommended mounting of  
the Modular Cabinet(s) is to a plywood back board which is securely mounted to the wall in the  
switch room. The plywood board should be a minimum of 1/2" thick and be secured to the wall  
by the appropriate hardware (i.e. toggle bolts, wood, or sheet metal screws, depending on the  
stud types) to ensure that the plywood will support the weight of the cabinets with all cards and  
cables installed.  
z
z
The RE may consist of up to 4 Modular Cabinets. The Modular Cabinets must be mounted  
next to each other (see Figure 4–1).  
The Modular Cabinet(s) must be mounted to the wall at a position where they are easily  
accessible for installation and maintenance of the system. Take into consideration that the  
number of cabinets may be expanded in the future.  
z
The Modular Cabinet(s) should be mounted at the normal working height. The lower edge of  
the Modular Cabinet(s) should be about 5.25 ft. above the floor.  
z
z
z
Above the Modular Cabinet(s) there should be at least 4" free space for air circulation.  
Modular Cabinets must be separated approximately 1/8" from each other.  
Do not mount anything within 1.5 ft. of the bottom of the cabinets to allow the bottom plate to  
swing down and to allow for cable entry from the bottom of the cabinet. See Fig. 4–1  
Installation of the Modular Cabinet(s)

4.11 Interconnecting Modular Cabinets  
After the Modular Cabinets have been mounted to the wall, the backplanes of the cabinets have to  
be interconnected using the flat ribbon cable from the interconnection set, NTMNB 101 105 (see  
Figure 4-9). Install one end of the cable in one of the cabinets. Feed the other end of the cable  
through the sides of the cabinets and insert it into the connector on the back plane. Make sure the  
connector’s latch closes.  
Ensure that an earth ground has been run to cabinet #1 (see Figure 4-8). Take the green/yellow  
ground cable from the interconnection set and connect the cable from the ground plate of the first  
cabinet to the ground plate of the second cabinet. Continue connecting the ground cables to the  
third and fourth cabinets as they are installed (see Figure 4-9).  
The system bus on the backplane is terminated on both sides with R–networks in a SIL socket.  
When the Modular Cabinets are connected together, R–networks must be present only at both  
ends of the extended bus (see Figure 4–9).

Figure 4–11.  
Fig. 4–11 Placement of the Securing Bar  
4.13 Add a Cabinet  
Adding a cabinet to an existing sytem requires planning to assure a successful addition with  
minimal downtime and problems. Both software and hardware changes need to be made to the  
existing system during the upgrade procedure.  
Read the entire procedure before starting this operation!  
There are some special things to take into account for the addition of a cabinet.

z
Any cabinet needs to have a minimum of two circuit boards installed in it for the power supply  
to operate correctly.  
If your new cabinet is ordered with only one circuit board, then you need to plan on moving  
another circuit board out of an existng cabinet. This may entail moving cables. Any  
movement of existing boards should be done after the cabinet is added and the system is back  
on line.  
z
z
z
z
What board(s) are you placing in the new cabinet and what slots are they going into? Refer to  
Section 5, Chapter 3.2.  
Watch the power consumption totals for the backplane in each cabinet. Refer to Section 4,  
Chapter 2.2.  
When am I going to do this? Downtime needs to be scheduled for this operation. Allow plenty  
of time and let all users know the schedule.  
You will be removing termination resistors and knockout plates. The rule is "Where two  
cabinets touch, remove the termination resistors and knockout plates in both cabinets at that  
point."  
Pre-planning Questions  
z
Where do you physically add the new cabinet? On which side of the existing cabinet(s) do you  
install the new cabinet?  
Examine your current system and compare it to Figure 4-1. Are you adding cabinet 2, or 3, or  
4? Plan to add your new cabinet in the location identified in this figure. Make sure the  
appropriate location on the wall is cleared out for the new cabinet.  
z
z
z
Where will the power supply(s) for the new cabinet be mounted?  
Power supply should not be mounted directly beneath cabinets because the heat from the  
power supply will rise directly into the cabinet. Mount them off to the side of the cabinets or at  
least 3 feet below the cabinets.  
Where will the additional LTU/CLU/SLU/DTU blocks be mounted?  
66 blocks should not be mounted directly beneath the bottom of the cabinets as the blocks will  
interfere with the drop down bottom of the cabinet and you might short something out on the  
block. Leave as least a foot or two of free space below the cabinets.  
How will the LTU/CLU/SLU/DTU cables be routed?  
All cables coming into or out of the cabinets come out of the bottom of the cabinets. Leave  
enough free space under the cabinets to form and route the cables to their termination point

The actual operation of adding a cabinet takes place in two steps, before the scheduled downtime  
and during the scheduled downtime. Before the scheduled downtime you can:  
z
z
Prepare the new cabinet.  
Hang the mounting bracket for the new cabinet.  
Once this is done and you are at the scheduled downtime you can:  
z
z
z
z
z
Add the new cabinet via CSMW.  
Power down the existing cabinets.  
Mount the new cabinet.  
Power the system back up.  
Testing and back up.  
Preparing the new cabinet  
Once the new cabinet location has been decided, you must prepare for installation. For the  
purpose of this discussion, we are adding a second cabinet to an existing one cabinet system.  
The following procedure works for this or a third or a fourth cabinet. The only differences will be  
which side of the backplane and cabinet you will be working with.  
We will be adding the second cabinet to the right hand side of cabinet #1 as you look at cabinet  
#1.  
z
Unpack the new cabinet. Make sure you get the bracket. It is in a plastic bag on the top of the  
packaging. Once you take the cabinet out of the plastic bag, remove the labels from the back  
of the cabinet.  
z
z
z
Remove the front cover, bottom plate, and card retention bar. Keep the covers, bar, and  
screws together.  
Lay the cabinet on its back and examine the backplane. Since the left side of the new cabinet  
is going up against cabinet #1, this is the side we are interested in.  
Locate the (3) termination resistors, R401, R402, and R407 on the backplane. Refer to  
Figures 4-9 and 4-10. With a pair of needle nose pliers pull the resistor packs up off the  
sockets on the backplane. DO THIS CAREFULLY. Save the resistors.  
Locate the knockout plate on the left side of the new cabinet. Refer to Figure 4-4. Remove  
this plate. DO THIS CAREFULLY. It is recommended that you use a fine tip pair of cutters to  
cut the plate out.  
Open the interconnect kit, NTMBN 101 05. Remove (2) of the metal shielding gaskets, refer to  
Figure 4-5, and install them into the knockout hole on the side of the new cabinet.  
Place the card slot label along the bottom of the cabinet directly below the card guides.  
Place the cabinet label along the top edge of the cabinet above the card guides.  
z
z
z
z
At this point, it might be a good idea to verify that the power wiring of the cabinet is correct. Take  
one of the power supplies for the new cabinet and hook it up to the terminal block on the bottom of  
the cabinet. Refer to Figure 19-2 for connection information.

Turn the power supply on and measure the voltage of the terminal block. The voltage should  
be -48VDC.  
If the voltage is correct, turn the cabinet power switch on. Measure the voltage on the terminal  
block again.  
Turn the cabinet power switch off.

Insert a circuit board into the cabinet in any slot. Turn the cabinet power switch on. If  
everything is all right, then a green LED at the very top of the circuit board should be lit. Ignore  
any other LEDs.  
Turn off the cabinet power switch and remove the circuit board. Turn off the power supply and  
disconnect the cabinet power supply.  
The new cabinet is ready to be mounted.  
Hang the mounting bracket for the new cabinet.  
Normally the mounting brackets for the cabinets are all mounted at the same time. Since we are  
adding a cabinet to an existing installation, we do not have that luxury. There are two ways to  
mount the new bracket.  
Method 1 - This can only be done when the system is shut down.  
z
When cabinet 1 is shut down, remove it from the bracket on the wall. Use the spacer off of the  
new bracket, See Figure 4-6, and spot the screw holes for the new bracket.  
Drill new holes for the new bracket and secure it to the wall.  
z

Replace cabinet number 1 on its bracket and secure it to the wall.  
Method 2 - Done while existing system is running.  
z
z
Measure from the top right hand corner of cabinet one, 1 7/8" over and 7/8" down. This is the  
spot for the left hand mounting bracket screw. Place the new bracket on the wall, center the  
left hand mounting hole over the mark you just made, level the bracket, and mark the center of  
the right hand mounting hole.  
Drill the holes for the screws and secure the bracket to the wall.  
Do not mount the new cabinet !

Remove the knockout plate from the right hand side of the existing cabinet. See Fig. 4-4. DO  
THIS CAREFULLY.  
Take the remaining two metal shielding gaskets from the installation kit, NTMNB 101 05, and  
insert them into the hole whre the knockout plate was.  
Mount the new cabinet  
z
Hang the new cabinet on the bracket on the wall. Position it to the right hand side of the  
bracket. This should give you enough room between the brackets so that the shielding  
brackets do not interfere with each other as you set the new cabinet against the wall.  
Once the new cabinet is on the bracket, push it up against the existing cabinet as close as  
possible. This will compress the fingers of the shielding gaskets.

Central Processing Unit (CPU) – REX-BRD0004 or 2/ROFNB 157 19/2  
5.1  
General  
Maintenance  
The CPU contains the following field–exchangeable parts (see Figure 5–4):  
z
z
z
z
z
CPU Firmware (Mobility) - RYS 105 447  
CPU Firmware (Standalone) - RYS 105 657  
CPU Firmware, Poll Processor - REX-SW0014 or RYS 105 663  
Sync FPGA (Field Programmable Gate Array) - RYSNB 101 24  
Lithium Battery (type DL2032)  
The CPU firmware is delivered as a separate item.  
The lithium battery is a back-up power supply for the Real Time Clock (RTC) on the CPU board.  
The RTC supplies the system date (year, month, day) and time (hours, minutes, seconds). If the  
lithium battery dies, the system will require UTAM activation whenever the CPU power is cycled  
unless it has been initialized as a non-UTAM system.  
5.2  
Board Description  
Functionality  
The CPU board is used in both a Standalone (SA) system and in a Mobility Server (MS) system.  
The firmware that is resident on the CPU board determines which type of system the board will  
function in.  
Firmware RYS 105 657 is for Standalone Systems  
Firmware RYS 105 447 is for Mobility Server Systems  
Synchronization  
If the CPU resides in a system that is part of multiple system configuration, PWT interface and  
frame synchronization is required. When the PWT air interface is synchronized, efficient use of  
the network capacity and seamless handovers between systems are possible when the coverage  
areas overlap. To achieve PWT air interface synchronization in a multiple system configuration,  
the respective CPUs (responsible for the frame timing) have to be in sync. CPUs are  
synchronized using a master/slave concept, where one master CPU supplies a synchronization  
signal to a number of slave CPUs. A slave CPU can act as a master for a further three slave  
CPUs, thus creating a multi level star network with a maximum of two levels, see Figure 5-1.

Fig. 5–1 Synchronization Topology  
Strap Settings  
As the master CPU determines the timing in the star network, it can either generate the frame  
timing on its own or synchronize it to an external source like a 2 Mbit/s link (DLU or DTU).  
Synchronizing to a 2 Mbit/s or 1.544Mbit/s link reduces the likelihood of frame slips on the link but  
is only allowed when the clock stability is better than 2 ppm. In the Master/Stand Alone mode the  
CPU provides the frame timing on its own. As a Slave/Standalone the CPU receives framing sync  
from the master RE. In Figure 5–2 an overview of the strap settings is given.  
When setting the CPU up as a master or slave, both of the Air Interface master/slave jumpers  
must be set the same. Refer to Figure 5.2 for the correct configuration.  
When the CPU is strapped as a master, the frame timing strap must be set correctly. Refer to  
Figure 5.2 for the correct configuration.  
When the CPU is strapped as a slave, the function of the frame timing strap is disabled and the  
position of this strap is irrelevant. If the CPU is strapped as a slave then there must be a Sync  
cable from the Sync Out on the master RE connected to the Sync In connector on the slave.  
Refer to Chapters 17 and 19 in Section 5 of the TPM for information on Sync cable connectivity.

The Sync In and Sync Out ports on the CPU are connected via two methods.  
Method 1: Refer to Chapter 18, Synchronization Distribution Board and Chapter 20, Modular  
Cabinet CPU Cabling. This method is the older method which incorporates an internally mounted,  
inside the modular cabinet, Synch Distribution board and cables.  
Method 2: Refer to Chapter 20, Modular Cabinet CPU Cabling, a newer method of connecting  
sync cables directly between master and slave CPUs without using internally mounted sync board  
and cables.  
Note: The Sync Distribution Boad (SDB) and cables mentioned in method 1 are no longer  
availabe or included in new systems. Method 2 must be used for any new installations or if the  
SDB and cables must be replaced on an existing installation.  
The SMS/printer, PC and general alarm ports are connected to the MCCB via factory installed  
cables.  
Interface characteristics of the printer and PC ports are:

Reset Button  
The CPU is provided with a reset button. If this button is pressed, the CPU and the rest of the RE  
are reset and perform a cold start as if the RE was switched off and on again.  
Note:  
Resetting the CPU may cause the synchronization slave CPUs, connected to this CPU, to lose  
their synchronization. Immediate synchronization can be enforced by resetting the slave CPUs  
after the synchronization master CPU has been reset. Bear in mind that a synchronization slave  
CPU can be a clock provider to other slave CPUs.

15.1 General  
There are 12 transformer-isolated digital front ends (ports) on the board that provide 12 individual  
digital lines. These digital lines can support up to 12 Portable Telephones.  
Maintenance  
Upgrades and re-programming of the DLU board’s flash memory are done via the RS232 serial  
cable and the serial port on the face of the DLU board (COM 1). The board does not need to be  
removed from the system during reprogramming but all twelve ports will be out of service during  
this process. The RJ-45 connectors should be disconnected from the DLU board before  
downloading software.  
The boards may be inserted into or removed from a live system. Other boards already in the  
system however, may reset during live insertion.  
The DLU will come pre-programed with software specific to each PBX. The DLU board will have a  
specific part number for each PBX it is to integrate with.  
The DLU is programable to accommodate the need for software enhancements and fixes.  
Note:  
Boards should be inserted /removed one at a time. All connections to the RJ45 connectors and the  
DB9 connector should be removed prior to live insertion or removal.

16.2 Base Station Cabling  
Each Base Station requires a minimum of 2 pairs of CAT3 unshielded twisted pair cable. These  
two pair will be SC0 (signalling channel 0) and SC1 (signalling channel 1). Besides being used for  
signalling there is also 48 volts provided between the two pair to power the Base Station. One pair  
is at a -48V potential with respect to the other pair.  
How far a Base Station may be powered on the two pair is shown in a chart in Section 4, Chapter  
4, Table 4-3. If the cable distance to the Base Station exceeds the value in the chart for 2 pair,  
then the EPP (Express Power Pair) may be used. The EPP is a third pair of wires brought out of  
the Radio Exchange that supplies -48V. The EPP contains two wires, EPP0 and EPP1, where  
EPP1 is positive with respect to EPP0.

Technical Product Manual - DCT1900  
The cable set, NTM/TSRNB 101 29, that connects the CLU/SLU to the MDF brings out the three  
pairs mentioned above: SC0, SC1, and EPP. Refer to Fig. 21-3, 66 Block Diagram in Chapter 21  
for the pin out of the 66 Block where this cable terminates.  
A minimum of -21V DC is required at the Base Station for it to operate. When a Base Station is  
located too far away from the Radio Exchange to be powered by the Radio Exchange, then power  
can be provided by a local -48V power supply or an AC to 48V DC adaptor. The power supply or  
adapter should be placed in the last Intermediate Distribution Frame before the Base Station.  
Hook the output of the power supply/adapter to the EPP wires going to the Base Station; DO NOT  
connect the EPP wires at the Radio Exchange. Only the two data pairs should go from the Radio  
Exchange to the Base Station in this situation. The EPP wires are picked up in the last  
Intermediate Distribution Frame where the Base Station’s power source is located.  
16.3 Base Station Cable Delay Measurement  
The cable delay in each of the cable pairs going to every Base Station must be measured in order  
to program the Base Station delays into the system at initialization time. This is necessary in order  
to synchronize all Base Stations in the system.  
Base Station cable delay may be measured by two methods, ADM or measurement with a TDR  
(Time Domain Reflectometer).  
ADM, or Automatic cable Delay Measurement, is a feature where the CPU automatically  
measures the delay in the cable hooked up to a Base Station. Beginning with the hardware and  
software releases listed below, the DCT1900 system can automatically determine the correct Base  
Station cable delay. This means that it is no longer mandatory to have a TDR (Time Domain  
Reflectometer) on each and every job site to measure the cable delays.

Technical Product Manual - DCT1900  
Correct implementation of the automatic delay measurement requires that the base station be  
connected to the Radio Exchange and powered when adding the base station using the CSMW  
software. In previous installations the software requested the measured delay value. With the  
above revisions, entering the default value of 0.1 microseconds will initiate the Auto Delay  
Measurement. In the “Add Base Station” command process, the SLU/ CLU-S will talk to the base  
station and determine the time delay. This determined value will never be displayed in any of the  
system screens. The delay table will always reflect the value of .1 if it was chosen. If you enter  
a TDR measured value other than 0.1, e.g.: 1.5, then this value will be used and displayed by the  
system.  
In automatic mode the system determines the cable delay measurement every time the base  
station is powered, reset or when it is added.  
Procedure  
1. Install and terminate the Base Station cable with a RJ-45 connector.  
2. Mount and connect the Base Station.  
3. At the base station window, refresh and verify that the status is NEW for every Base Station to  
be added. If it is not, then trouble shoot the lines and hardware. In addition, a red LED on  
each of the CLU-S/SLU boards indicates a newly connected Base Station.  
4. Add the Base Stations by selecting the CLU address, the base station port and the cable delay  
value which can be set to automatic or manual.  
5. After all of the Base Stations have been added, each new base station will have a "Pending”  
status if the RE was initialized as a UTAM system. If the RE was initialized as a non-UTAM  
system, the status will change to AVAILABLE.  
6. Activate the Base Stations with the correct UTAM password if the RE was initialized as a  
UTAM system.  
7. Refresh the window to see the status of the new Base Stations as "Available."  
8. Back up the system data.  
9. Set two or more portables in engineering mode to perform a "walk around" test. Check for  
proper system operation, voice quality, handovers, and coverage.  
Note:  
The new DCT1900 Auto Delay Measurement system does not eliminate the need to use a TDR.  
The quality of the cable, and the possibility of wiring errors could negate the automatic  
measurement capability.  
The second method, using a TDR, is explained in the following paragraph.  
Base Station delays are measured at the RE with a TDR connected first to cable data pair SC0  
and then to cable SC1 with the cable open ended at the far end and then shorted at the far end.  
While it is not necessary to determine the delay in the EPP pairs, if they are used, it is  
recommended that these pairs be checked with the TDR to ensure that they are going to where  
they are supposed to be and are not open/shorted anywhere.  
1. Make sure that the Base Station cable is unplugged from the Base Station.  
2. Disconnect the relevant connector from the relevant CLU or SLU.  
3. Connect the TDR to cable pair SC0 or SC1 or EPP (refer to Chapter 25 on how to use the  
TDR).  
4. Measure the cable delay. The measured delay is the time between sending a pulse down the  
line and receiving the echo. The resulting value must have an accuracy of 200 ns  
(corresponding with 18–27 ft.).

5. Enter the measured delay value into the correct column on the Base Station identification and  
Location chart (refer to “Table 21-1, Example of Base Station Administration” in Chapter 21)  
along with the Base Station number and location.  
6. Repeat the delay measurement for all Base Stations connected to the CLU or SLU.  
7. Re–connect the connectors to the CLU or SLU.  
If applicable, repeat the delay measurement for the Base Stations connected to the other CLUs  
and SLUs.  
16.4 Installation Criteria  
The Base Station should always be mounted such that the antennas are vertical with respect to  
the floor or ceiling. Two types of antennas are available to facilitate the correct orientation of the  
Base Station. One set is a vertical antenna for wall mounting of the Base Station and the other set  
is a right angle antenna that allows the Base Station to be mounted on the ceiling.  
The Base Station should never be mounted above the ceiling tiles as this reduces the coverage  
area. Base Stations should not be mounted near large metal objects, such as pipes or air  
conditioning conduits. Do not mount Base Stations directly on I-Beams or lamp poles, as these  
objects tend to distort the RF field which reduces the effectiveness of the RF coverage area. Use  
the Base Station outdoor wall mounting kit (see Paragraph 16.3.4) or a factory hanging device  
(see Paragraph 16.3.2). Do not mount the Base Station more than 20 ft. high.  
Note:  
When mounting Base Stations near to each other to provide additional call capacity, it is necessary  
to maintain at least 40 inches spacing between Base Stations.  
The location where the Base Station is to be mounted is determined either by a previous site  
survey or by the needs of the customer when adding to a system.  
The following is a recommended order of installing a Base Station:

16.5 Connecting the Base Station Plug to the Cable  
Note:  
Make sure that there is no power applied to the Base Station cable on which you are working.  
Either the power cable or the signal cable on the front of the CLU/SLU should be disconnected  
before connecting the cable to the RJ45 plug. -48V DC for powering the Base Stations is provided  
between the data pairs and on the EPP wires.  
1. Cut the Base Station cable to the correct length and connect the cable to the RJ45 Modular  
Jack (see Fig. 16-2 Connector Pinning).  
2. If an external power supply or AC/DC converter is used to power the Base Station, it is  
recommended that this device be located in the last IDF in the signal path. Connection of the  
output voltage from these devices will be made to the EPP pairs going out to the Base Station.

16.6 Base Station Mounting - Indoor  
16.6.1 Wall Mount  
The Base Station comes with its own Base Station mounting bracket. The necessary antenna are  
ordered and shipped separately. The Base Station is to be mounted such that when wall mounted  
the top of the antenna is at least 6 inches below the ceiling. If the ceiling is made of metal or  
contains a metal plate, the distance between the metal plate and the antenna must be at least one  
foot.  
Once the location where the Base Station is to be mounted has been determined, take the  
mounting plate (see Fig. 16-1, Base Station Cover and Back) and spot it where the Base Station is  
to be mounted.  
1. Mark the location for the mounting hardware.  
2. Secure the rear bracket to the wall. Use #6 mounting hardware. The side of the bracket with  
the part no. SXANB 101 127/X goes towards the wall.  
3. Plug the Base Station cable into either one of the RJ45 jacks on the back of the Base Station.  
4. Place the Base Station over the rear plate on the wall and slide it down until the Base Station  
locks in place onto the rear bracket.  
5. Connect the antenna to the Base Station, then slide the rubber grommet supplied with the  
antenna kit down over the antennas until they are firmly seated in the Base Station itself.  
16.6.2 Ceiling Mount  
A kit, part number NTM 201 1754 is provided for the ceiling mounting of base stations. Ine kit is  
required for each ceiling mounted base station. Teh following instructions, also the kit are included

The chain is to be used as two continuous pieces. Loop the chains around the I Beam and connect  
them to the screw eyes with the Quick Links. (See Figure 16-10.)  
Always use right angle antennas.  
Once the Base Station is mounted and the cable is connected to the base station, make sure that  
the Base Station cable is tie wrapped to one of the chains. This acts as a retention device so that  
the Base Station does not slide off of the mounting bracket.

Warning: Installation of outside equipment is to be installed in accordance with required  
electrical code to include NEC 725, 800, 810 AND CEC 54, 60 (Lightning and ground  
requirements).  
When mounting outdoors or to exterior building walls or large metal objects or to lamp posts, it is  
imperative that the Base Station is not placed directly up against any or these objects. Use of the  
outdoor/wall mounting kit, NTM 201 1718, is recommended. The following instructions are  
contained within the outdoor/wall mounting kit, NTM 201 1718.  
Outdoor Base Station Mounting Instruction  
Introduction  
For outdoor and campus applications, standard (indoor) DCT1900 Base Stations are mounted in  
the weatherproof fiberglass housing. This industry recognized (NEMA, UL, IEC, CSA) housing is  
designed for pole or wall-mounting commercial electronic and telephone equipment in outdoor  
areas, as well as indoor industrial applications where chemical vapors and/or high dust  
contamination exists.  
Precise determination of Base Station location is identified at the time of an RF site survey to  
provide optimal coverage (per Base Station). Housings can sometimes be directly mounted on  
building surfaces, however radio coverage is generally not optimal under this condition. In

locations where coverage area and range need to be optimized, it is important to mount Base  
Stations several wavelengths (~6-18") away from building surfaces, and in the case of large metal  
building surfaces, absolutely imperative.  
The components within the Outdoor Base Station Mounting Kit provide this needed functionality.  
The key components consist of two Mounting Plates and two Mounting Arms. The Small-Pattern  
Mounting Plate is always used on the weatherproof housing (to avoid placing too much metal near  
the Base Station). The Large-Pattern Mounting Plate is secured to the building surface. It has a  
larger surface area with several hole spacings for flexibility in mounting on varied and irregular  
building surfaces. The Mounting Arms are supplied in 3 lengths depending on the application  
need. The combinations of these components provide the installer the ability to securely mount the  
housing on almost any axis or location, as can be seen in Figure 16-12.

In many outdoor and campus applications, coverage is a major issue. To minimize the number of  
Base Stations, they need to be strategically placed to create the best overlapping radio cells. For  
example, it is common to place Base Stations at the corners of tall buildings to capitalize on the  
omnidirectional radiation characteristics of the unit. The Mounting Kit provides this capability.  
Mounting Instructions  
1. Secure Large Pattern Mounting Plate to the Building Surface  
The mounting plates and arm are made of lightweight aluminum, and the Weatherproof  
Housing (including the Base Station) weighs approximately 7 lbs. To insure structural integrity  
and safety, the mounting plate must be secured firmly to the building surface using at least  
four of the 3/8" dia. stainless steel fasteners provided in the kit.

Technical Product Manual - DCT1900  
Note that mounting fasteners differ according to the building surface being mounted to.  
When mounting to wood surfaces, standard 3/8" "lag bolts" are to be used. Generally  
however, buildings of concrete and/or brick construction are most common. In these cases  
the Mounting Plate must be secured with 4 expanding anchors suitable for this type of  
construction. Two types of expanding anchors are included in the kit and must be installed as  
follows:  
Caution: Note that the correct anchor must be chosen for these types of construction and  
must be mounted in 3/8" holes drilled at least 1 1/2" deep.  
For solid concrete:  
ITW Ramset/Red Head "Trubolt Wedge Anchor"  
Part No. WW-3822 Tightened @ 25.ft. lbs.  
For solid concrete,  
hollow concrete block,  
or brick:  
ITW Ramset/Red Head "Dynabolt" Sleeves,  
Part No. SHN-3817 Tightened @ 15 ft. lbs.  
Proper installation of the above fasteners provides more than 1300 lbs. of pull or shear  
strength (per fastener).  
2. Secure the Base Station Mounting Bracket to the Inside of the Weatherproof Housing  
See Figure 16-13. Locate the mounting bracket (supplied with the Base Station) in the position  
and drill two 5/32” diameter holes for mounting. Apply a small amount of silicon-seal to the  
surfaces. Next, secure the Base Station Mounting Bracket with two 6-32 x 5/8” pan-head  
screws, locking hex nut and flatwashers provided.  
3. Secure Small Pattern Mounting Plate to the Weatherproof Housing Outer Surface  
See Figure 16-14 Position the Small Pattern Mounting Plate on the lower back side of the  
weatherproof housing and, using it as a drill guide, drill four 0.375" diameter holes through the  
housing. Apply a small amount of silicon rubber seal within and around the holes on the  
INSIDE surface of the housing and then mount the plate in the orientation desired for the  
application using the provided 3/8”-16 x 1” hardware (bolt, flatwasher and nut). The blot head  
and washer shall be mounted from inside the housing as shown. Use silicon-seal to insure a  
weatherproof seal around the bolt head and washer.  
4. Provide Signal/Power Cable Access Into the Housing  
Depending on the desired orientation of the weatherproof housing, choose a satisfactory  
cable-entry point on or near the bottom of the housing and drill a 0.375" hole to accommodate  
the provided 1/4" rubber grommet. Use silicon-seal to weatherproof this cable-entry as  
needed.  
5. Secure the Weatherproof Housing and Mounting Arm to the Plate Mounted on the Building  
Surface  
The weatherproof housing can now be attached to the building using either length of Mounting  
Arm provided in the kit. It may be desirable to run the signal/power cable to the Base Station  
inside the Mounting Arm, entering and exiting the cable through the slots provided. Using the  
5/16"-18 bolt and locking hex-nut provided, lock the Mounting Arm in place using the locating  
holes in the Mounting Plate tubes at each end. (Do not overtighten the hardware as this could  
distort the tubes, making future disassembly difficult.)

Technical Product Manual - DCT1900  
Caution: Mounting Arms of 12" and 18" are provided. The "creative" use of longer mounting  
arms is NOT ALLOWED as considerable forces could be generated due to combinations of  
housing weight, length of the mounting arm, wind loading, earthquakes and/or vibration.  
These forces could result in pulling out the mounting anchors from the building with destructive  
results including falling hardware, including possible injury or death to people below.  
6. Complete the Installation of the Base Station  
After securing the weatherproof housing to the building surface (above), terminate the signal/  
power cable inside the housing with the recommended Modular Plug(s), leaving a service-loop  
of approximately 12". Connect the Modular Plug(s) to the DCT1900 Base Station and install it  
in the housing by hanging it on the bracket already mounted inside the housing from earlier  
steps.  
After verification of operation, secure the hinged door of the weatherproof housing.

18.2 Installation  
The SDB comes as part of the installation set sync port kit (NTMNB 101 107) and must be installed  
in the cabinet where the CPU1 is going to reside (refer to Paragraph 4.7 of Chapter 4). For the  
installation of the cables to the CPU1 refer to Chapter 19, CPU1 Cabling. The external sync in and  
out cables are part of the sync port kit and are required if PWT air interface synchronization is  
needed in a multi DCT1900 system environment. They must meet the requirements in Paragraph  
18.3 (see Figure 18-3).  
18.3 External Sync Cable  
When there are multiple DCT1900 systems with overlapping coverage areas it is necessary to  
synchronize the CPUs of the systems together. This is done by connecting an external sync cable  
from one of the sync out ports on the master CPU’s sync board to the sync in port on one of the  
slave CPU’s sync board.  
A pre-made external sync cable, TSR 951 284, is available. The specifications for this cable are  
included below. If this cable is not long enough then a cable must be constructed on site. Refer to  
the enclosed specifications to construct this cable. If the 6 conductor shielded flat cable is not  
available then a single pair of 120 ohm twisted shielded pair may be used.  
The signal delay in the external sync cable must be determined. For the cable TSR 951 284 it is  
0.04μs. A cable made on site must be measured using a TDR (Refer to Paragraph 18.4).  
Once the delay is known, this value is entered into the slave system’s CPU during its’ initialization.  
Refer to the Cordless System Software User’s Guide (LZB 119 2664), Appendix I, on how to enter  
this delay.

18.4 Sync Input Cable Delay Measurement  
The external sync input cable delay must be measured in order to input the system  
synchronization delay into the system at initialization. The system synchronization delay  
compensates for the delay introduced by the cable. The external sync input cable delay is  
measured as follows:  
1. Make sure that the other end of the external sync input cable is not connected.  
2. Connect a TDR to the terminals 3 and 4 on this end.  
3. Measure the cable delay. The resulting value must have an accuracy of 50ns (corresponding  
to 16ft. – 33ft.).  
4. Note the cable delay value.

CHAPTER 19  
Modular Cabinet – Power Cabling  
19.1 Introduction  
This chapter describes the installation of the power cables in two different versions of the Modular  
Cabinet. The installation depends on the number of external -48Vdc power supplies and on how  
the Base Stations are powered.  
WARNING  
Disconnect or switch off all power supply sources before servicing any power  
supply circuit.

19.3 Installation  
Modular Cabinet Powered by an External 300 Watt –48Vdc Power Supply  
When the Modular Cabinet is powered by an external -48V power supply, Base Station power can  
be supplied to the CLUs/SLUs in the following ways:  
z
to maximum 3 CLUs/SLUs via the backplane PW-BP connection on the MCCB  
to maximum 4 CLUs/SLUs via the PW–EXT connection on the MCCB  
z
The advantage of powering via the backplane is that the Base Station is switched off when the  
Modular Cabinet is switched off by the switch on the cabinet.  
When combining both methods, a maximum of 7 CLUs/SLUs can be provided with Base Station  
power.  
Modular cabinet powered by a -48Vdc PBX power supply  
When the modular cabinet is powered by a -48Vdc PBX power supply, Base Station power can  
be supplied into the CLUs/SLUs in the following ways:  
-
to a maximum of 3 CLUs/SLUs via the PW-BP connection on the MCCB  
-
to a maximum of 7 CLUs/SLUs via the PW-EXT connection on the MCCB  
When combining both methods, a maximum of 9 CLUs/SLUs can be provided with Base  
Station power.  
WARNING  
When using the PBX power supply, make sure that the capacity of the  
supply is sufficient to power both the PBX and the Modular Cabinet.  
Base Station Power Supplied to a Maximum of 3 CLUs via the Backplane

19.5 Installation  
Modular Cabinet Powered by an External 300Watt -48Vdc Power Supply  
When the Modular Cabinet is powered by an external -48V power supply, Base Station power can  
be supplied to the CLUs/SLUs in the following ways:  
z
to maximum 3 CLUs/SLUs via the backplane PW-BP connection on the MCCB  
to maximum 4 CLUs/SLUs via the PW–EXT connection on the MCCB  
z
The advantage of powering via the backplane is that the Base Station is switched off when the  
Modular Cabinet is switched off by the switch on the cabinet.  
When combining both methods, a maximum of 7 CLUs/SLUs can be provided with Base Station  
power.  
Modular cabinet powered by a -48Vdc PBX power supply  
When the modular cabinet is powered by a -48Vdc PBX power supply, Base Station power can  
be supplied into the CLUs/SLUs in the following ways:  
-
to a maximum of 3 CLUs/SLUs via the PW-BP connection on the MCCB  
-
to a maximum of 7 CLUs/SLUs via the PW-EXT connection on the MCCB  
When combining both methods, a maximum of 9 CLUs/SLUs can be provided with Base  
Station power.  
Warning  
When using the PBX power supply, make sure that the capacity of the supply  
is sufficient to power both the PBX and the Modular Cabinet.

CHAPTER 21  
Modular Cabinet – CLU/SLU to Base Station Cabling  
21.1 Introduction  
This chapter describes all the cabling between the CLU or SLU and the Base Station. Refer to  
Chapter 19 on how to supply Base Station power for CLUs or SLUs.  
The Modular Cabinet is provided with a ground strip to connect the CLU or SLU cables to ground  
(see Fig. 21–1). These ground connections are necessary for EMI suppression reasons.  
Two cables sets are used to interconnect the CLU/SLU to the MDF. Cable set NTM/TSRNB 101  
29 is 16 ft. long and is terminated in a 25 pair amphenol. Cable set NTM/TSRNB 101 46 is two 82  
ft. 12 pair cables unterminated.

21.2 Installation of Cables  
Note:  
Base Stations with cables longer than 1.3 miles up to 2.17 miles must always be connected to a  
CLU with product code REX-BRD0014 or ROFNB 157 11/2.  
Base Station with cables of up to 1.3 miles can be connected to a CLU/SLU with product code  
REX-BRD0014 (ROFNB 157 11/2) or REX-BRD0015 (ROFNB 157 16/1) or REX-BRD0016  
(ROFNB 157 16/2).  
CLU/SLU to the MDF  
Cable sets NTM/TSRNB 101 29 and NTM/TSRNB 101 46 connect from the CLU/SLU boards in  
the modular cabinet to 66 blocks (or equivalents) on the MDF. Refer to the Table 21-2 and 21-3 for  
the pinout of the respective cables.  
1. Connect the plug of CLU/MDF cable TSRNB 101 29/2 (or the long cable TSRNB 101 46/2) to  
the upper connector of the furthest right CLU or SLU as shown in Fig. 21–2.  
2. Connect the plug of CLU/MDF cable TSRNB 101 29/1 (or the long cable TSRNB 101 46/1) to  
the lower connector of the same CLU or SLU as in the previous step.  
3. Screw the shielding clamp of TSRNB 101 29/2 (or TSRNB 101 46/2) to the furthest right free  
position on the ground strip using two M3 x 10 torx screws delivered with the Modular Cabinet.  
4. Screw the shielding clamp of TSRNB 101 29/1 (or TSRNB 101 46/1) to the next furthest right  
free position on the ground strip.  
5. Connect the cable set TSRNB 101 29 to the provided 66 blocks via the 25 pair amphenol  
connector. Connect the cable set TSRNB 101 46 to the provided 66 blocks, or any other block  
by punching the wires down. Circuit wiring is shown in Table 21-2.  
Note:  
To meet EMC requirements, the cable should never be cut to a length shorter than 8.20 ft.

Base Station Power  
The following installation steps are necessary when the Base Stations are powered via the  
Modular Cabinet. Refer to Chapter 19 on how to supply Base Station power to the MCCB.  
1. Connect connectors PW1 on the MCCB to the Base Station power connectors on the furthest  
left CLU or SLU using the CLU/MCCB Power cable (see Fig. 21–2).  
2. Connect PW2 – PW7 to the power connections of the other CLU or SLUs starting at the next  
CLU or SLU.  
Cabling from the MDF to the Base Station  
Refer to Section 4, Chapter 4, Base Station Powering for cable type information. Figure 21-3  
shows the pinout of the 66 blocks that the cable set NTM/TSRNB 101 29 terminates on. NOTICE  
that only 3 pairs are brought out for each base station. These are SC0, SC1 and EPP0/1.  
You must hook up the first 2 pair, SC0 and SC1, for each base station. The third pair, EPP0/1, is  
only used when additional power is required due to cabling distances. (Refer to Section 4,  
Chapter 4, Base Station Powering).  
If a fourth pair (white/brown pair) is required then it may be punched down on top of the existing  
EPP0/1, pair (white/green pair).

CHAPTER 23  
Modular Cabinet – LTU Cabling  
23.1 Introduction  
This chapter describes the installation of the cabling between the LTU(s) and the PBX. The LTU  
cable set, NTM/TSRNB 101 31, consists of two 12 pair cables terminated in one 25 pair amphenol  
connector. The other end of each cable ends in three Ericsson half connectors. Refer to Chapter  
26, Modular Cabinet cables, for a cable schematic and physical description.  
Each LTU cable is designed to connect three LTU boards, thus 24 analog extensions, to a single  
66 Block. The cable terminates in a 25 pair male amphenol connector which mates with a  
Siemens 66m250 Block or the connector can be cut off and the cables punched down on other  
types of blocks. Refer to Table 23-1 for a pin out of the cable  
The Modular Cabinet is provided with a ground strip to connect the cables from the LTUs and the  
CLUs to ground. These ground connections are necessary for EMI suppression reasons.  
Note:  
The orientation of the shielding clamps shall be according to Figure 23-1. If the clamp is positioned  
at the wrong side, remove the clamp and position it properly.

appear on the second to the last pair of the punch down clips at the bottom of the Block. Pair 25 is  
not used and is not connected.  
Note:  
To meet the EMC requirements, the cable should never be cut to a length shorter than 8.2 ft.  
Signalling Ground for LTU when using Earth Signalling for Recall  
The signalling ground is only applicable when earth signalling is used instead of timed break  
signalling. The MCCB connect the signalling ground from the PBX to maximum of 7 LTUs.  
1. Connect the PBX signalling ground from the MDF to the PBX screw connector on the MCCB.  
2. If more Modular Cabinets are used in a system, chain the PBX connectors.  
3. Connect an LTU/MCCB ground cable (TSRNB 101 035) to the LTU1 connector on the MCCB.  
4. Connect the other end of the LTU/MCCB ground cable to the LTU ground connector on the  
furthest left LTU (see Fig. 23-2).

Installation Instructions, Modular Cabinet – DLU Cabling  
CHAPTER 24  
Modular Cabinet – DLU Cabling  
24.1 Introduction  
This chapter describes the installation of the cabling between the DLU(s) and the PBX. The DLU  
cable set, AWS1019, consists of (12) 2 pair cables individually terminated in a RJ11 connector.  
Each DLU cable is designed to connect two DLU boards, thus 24 digital extensions, to a single 66  
Block. The cable terminates in a 25 pair male AMP connector which mates with a Siemens  
66m250 Block or the connector can be cut off and the cables punched down on other types of  
blocks. Refer to Table 24-1 for a pin out of the cable  
The Modular Cabinet is provided with a ground strip to connect the cables from the DLUs and the  
CLUs to ground. These ground connections are necessary for EMI suppression reasons.  
24.2 Installation  
The 24 connectors on the DLU end of the cables are labelled P1 through P24 and should be  
installed as shown in Fig. 24-2. Connector 1 goes to the first port of the DLU which is at the bottom  
of the board. The male AMP is connected to the 66 Block.  
The orientation of the shielding clamps should be as shown in Fig. 24-1.

CHAPTER 25  
Use of TDR  
25.1 Introduction  
When programming Remote Base Stations using the CSMW Software, it is necessary to  
determine the time delay of the Base Station cable. This is done using a TDR (Time Domain  
Reflectometer). See the following paragraph for instruction on how to measure the delay of the  
Base Station cable.  
25.2 Determining the Delay of Remote Base Station Cable  
The following instructions explain how delay is measured using the Tektronix model 1503B or  
1503C TDR.  
Refer to Figure 25-1 for an illustration of the front panel controls. In this illustration, each control is  
numbered and the numbers are used to identify each control in the procedure that follows.  
Fig.25-1 TDR Controls  
1. Turn power on (7). When you see a horizontal trace and division marks on the screen, the  
TDR is ready to use.  
2. Set Impedance (2) to 93 ohms.  
3. Set Noise Filter (3) to 1 AVG.  
4. Set Vertical Scale (4) to 0.00dB  
5. Set DIST/DIV (5) to 100 ft.  
6. Set V (6) to .99.  
p
7. Set Pulse Width (8) to 100 nS.  
8. Center the trace using the vertical POSITION control (9).  
9. Connect the test cable (terminated with two alligator clips) to the input jack (1).

Technical Product Manual - DCT1900  
10. A waveform similar to the one shown in Figure 25-1 should be displayed, however the vertical  
pulse will be located at the left edge of the screen. This is the transmitted pulse the TDR uses  
to determine the length of the cable.  
11. Rotate the horizontal POSITION control (10) until the vertical line it controls is all the way  
against the left edge of the screen. At this point, the upper right corner of the display should  
show either 0.00 ft. or some negative value.  
12. Connect the pair to be measured to the test cable using the alligator clips. At this point the pair  
should not be connected to either the base station or the radio exchange, and should be left  
open-circuited at the far end. Adjust the DIST/DIV control (5) until the display shows not only  
the transmitted pulse on the left (as in Figure 25-1) but also the reflected pulse farther to the  
right. This pulse should have the same polarity (positive) as the transmitted pulse. It may be  
necessary to adjust the Vertical Scale (4) control and/or the Pulse Width control (8) so that the  
transmitted and reflected pulses are clearly defined and separated as in Figure 25-2.  
Figure 24-2 Transmitted and Reflected Pulses  
Now, adjust the horizontal Position control (10) until the vertical line it controls is exactly at the  
leading edge of the reflected pulse. At this point, have someone short the pair at the far end while  
observing the display. The reflected pulse should invert as the pair is shorted. If not, the pair may  
be open at some point or you may be testing the wrong pair. Correct the condition and retest until  
the proper result is obtained.  
Have the person at the far end remove the short and observe that the reflected pulse returns to  
positive polarity and that it is still aligned with the vertical line. If the pulse has shifted, this is an  
indication that the pair may be open on one side. Correct the condition and retest until the proper  
result is obtained.  
Note the indication in the upper right corner of the display, indicated in feet. Multiply this indicated  
length in feet by the constant .001025 microseconds/foot. This will yield the delay of the pair in  
microseconds.  
Example: Assume a reading of 167.7 ft.  
167.7 ft. x .001025 = .17189 microseconds  
Record the calculated delay in microseconds. This value will be used to determine the proper  
value to enter when adding a Remote Base Station using the Cordless System Manager software  
for windows.  
As the system allows entries only in increments of 0.1, it will be necessary to round.

Technical Product Manual - DCT1900  
Examples:  
.17189 should be rounded to .2  
.13125 should be rounded to .1  
Follow this procedure for each Remote Base Station pair to ensure that they are in good condition  
and that the delay is identical for pairs that go to the same base station.

26.10 CLU/MDF Cable Set – NTM/TSRNB 101 29  
The CLU/MDF Cable Set (see Figures 26-10 through 26-12) consists of two shielded cables  
(TSRNB 101 29/1 and TSRNB 101 29/2). The cables are used to connect a CLU or a SLU to the  
MDF. The shielding of the cables is connected to the cabinet via a clamp which also functions as a  
strain relief. The only difference between the two cables is the location on the cable where the  
clamp is attached to the shielding. This is respectively 13 in. from the connector for cable TSRNB  
101 29/1 and 18 in. for cable TSRNB 101 29/2. The cables are terminated in a male, 25 pair  
amphenol connector for ease of connection to the MDF. If the MDF blocks do not support this type  
of connector, then the connector may be cut off and the wires punched down on the MDF.  
The cable set supports eight Base Stations. This may be on one block via the 25 pair connector or  
across several blocks if the connector is cut off.

CHAPTER 1  
Introduction  
This section describes a series of checks and tests that have to be executed after completing the  
installation and initialization of the DCT1900 system. The purpose of these tests is to verify that the  
DCT1900 system is functioning properly after the installation is completed. If it appears that a part  
is malfunctioning while the system is installed correctly (i.e.: no cabling faults, no configuration  
faults), the technician must consult Section 7, "Maintenance" included in this manual for fault  
finding.  
Note:  
Be sure that all batteries in the Portable Telephones are charged up before executing the tests.

Commissioning, Synchronization Test  
CHAPTER 5  
Synchronization Test  
5.1  
General  
This test checks if two DCT1900 systems, whose coverage areas partly overlap and are  
connected to the same synchronization network, are correctly synchronized. The test is performed  
by setting up a call and moving from the coverage area of one DCT1900 system to the other.  
5.2  
Test  
1. Check if both DCT1900 systems report "system synchronization available" by observing the  
system screen of the CSMW Software (menu: System Manager-Control-System). If a system  
is not synchronized you can force synchronization by a system reset (ongoing calls are  
dropped), assuming that the synchronization network is set–up correctly.  
2. Ensure that the Portable Telephone is correctly initialized and that both DCT1900 systems are  
in the same system range using the configuration tool.  
3. Switch off the Portable Telephone and move to the coverage area of one of the DCT1900  
systems.  
4. Switch on the Portable Telephone and observe if the Portable Telephone registers itself to the  
system.  
5. Make a call to a fixed or stationary telephone.  
6. Monitor the speech quality while moving to the coverage area of the other DCT1900 system. If  
the call is not dropped and the speech quality remains good (no crackling sounds or mutes),  
then both systems are correctly synchronized.  
7. You can verify the result by moving back again while making a call.

Commissioning, Radio Coverage Verification  
CHAPTER 4  
Radio Coverage Verification  
4.1  
General  
The radio coverage verification consists of two tests:  
z
Base Station test  
z
Area coverage test  
Ensure that the Base Stations are properly installed. Please take the following into account:  
z
z
z
Mounting  
Wiring  
Initialization (CSMW Software)  
The Base Station should always be mounted such that the antennas are vertical with respect to  
the floor or ceiling. Two types of antennas are available to facilitate the correct orientation of the  
Base Station. One set is a vertical antenna for wall mounting of the Base Station and the other set  
is a right angle antenna that allows the Base Station to be mounted on the ceiling.  
The Base Station should never be mounted above the ceiling tiles as this reduces the coverage  
area. Base Stations should not be mounted near large metal objects, such as pipes or air  
conditioning conduits. Do not mount Base Stations directly on I-Beams or lamp poles, as these  
objects tend to distort the RF field which reduces the effectiveness of the RF coverage area. Use  
the Base Station outdoor wall mounting kit (see Section 5, Installation Instructions, Chapter 16,  
Base Station – KRC 101 1371, Paragraph 16.7) or a factory hanging device (see Section 5,  
Installation Instructions, Chapter 16, Base Station – KRC 101 1371, Paragraph 16.6.3). Do not  
mount the Base Station more than 20 ft. high.  
Note:  
When mounting base stations nearby each other to provide additional call capacity, it is necessary  
to maintain at least 40 inches spacing between base stations.  
The location where the Base Station is to be mounted is determined either by a previous site  
survey or by the needs of the customer when adding to a system.  
The following is a recommended order of installing a Base Station:  
-
-
-
-
Base Station cable delay measurement  
Mounting the Base Station - indoor  
Mounting the Base Station - outdoor  
Connecting the Base Station plug to the cable  
4.2  
Base Station Test  
The purpose of this test is to check if all Base Stations are operational.  
Test  
1. Put a Portable Telephone in the DCA mode (refer to Section 7, "Maintenance" in this manual).  
2. Take the floor plan of the area where the Base Stations are indicated with their corresponding  
Base Station number or use the Base Station identification and location sheet in Section 5,  
"Installation Instructions" in this manual.

Commissioning, Radio Coverage Verification  
3. Move closer to each Base Station and check that the Portable Telephone locks to it (the DCA  
should display the correct Base Station number).  
After having checked that all Base Stations are operational, proceed to the area coverage test.  
4.3  
Area Coverage Test  
The purpose of this test is to verify that the field strength is sufficient within the coverage area and  
that the Base Station delay values are correct. Sufficient field strength and proper Base Station  
delay values enable good speech quality everywhere within the covered area (rooms, elevator  
shafts, staircases). This test is executed with two Portable Telephones and requires two persons.  
Test  
1. Place the Portable Telephone in the DCA mode (refer to Section 7, "Maintenance" in this  
manual).  
2. Call the other Portable Telephone.  
3. One Portable Telephone user should now start moving around in the covered area.  
4. Both users must check that a good speech quality is maintained everywhere. Pay special  
attention to areas such as edges of a building and areas behind metal structures where  
reduced speech quality is likely.  
5. Mark areas where RQI is not stable on 20  
and where cracking sounds or mutes are heard.  
hex  
4.4  
Radio Coverage Verification  
This test procedure is in addition to 4.3, "Area Coverage Test."  
Test  
1. Place the Portable Telephone in DCA mode (refer to Section 7, "Maintenance" in this manual).  
2. Call the other Portable Telephone, or any other phone, and leave the call up for the duration of  
the testing.  
3. Select the new DCA menu item MER tests. Scroll down to GEN. Setup (yes), scroll down to  
DCA-SERVICE (yes), scroll down to MER tests (yes).  
4. Scroll down to MER long (yes). A counter on the upper left of the screen will start counting to  
F03C (10 minutes). MER short counter will be set to 7D0 (20 seconds) if MER short is  
selected.  
5. MER test Portable user should now start moving around the covered area.  
6. The test can be paused and/or unpaused using thekey. The frame counter can be reset to  
zero restarting the test using the key. Once the test is started it will not stop unless the test is  
paused or the total number of frames is reached, regardless of whether or not the user stays in  
a MER test screen.

CHAPTER 2  
Visual Checks  
2.1  
General  
Visual inspection consists of checking the LEDs on the system boards and the availability of all  
system boards and Base Stations.  
2.2  
LEDs on the System Boards  
Check the following LEDs:  
1. On the CPU board only the upper–most green LED (LED1) must be on. LED6 blinks  
periodically according to the setting of the ACK test (see Section 7, "Maintenance" in this  
manual).  
2. All green LEDs on all other system boards must be on.  
3. Red LEDs must be off. In certain situations a red LED on the DTU board can be on, see  
Paragraph 2.3.  
2.3  
Availability of all System Boards and Base Stations  
The status of the system boards and Base Stations can be checked with the help of the system  
menu of the CSMW Software. All hardware/peripherals must have the AVE status. However, for  
the DTU, CLU and SLU boards the following exceptions may be applicable:  
z
z
DTU board  
A Digital Trunk Circuit (DTC) that is not connected to the PBX must have its corresponding L1  
with the status NEW and L2 with no status indication (LED4 is on).  
CLU and SLU board  
Peripherals (CLCs) that are not connected to Base Stations will have the status PNP (Possibly  
Not Present). Peripherals with initialized (delay value specified) Base Stations should have the  
status AVE. A CLC with a non-initialized Base Station has the status NEW causing LED4 of  
the CLU or SLU board to be on.

Technical Product Manual - DCT1900  
Maintenance, Maintenance Philosophy  
CHAPTER 1  
Maintenance Philosophy  
1.1  
Concept of Maintenance  
The DCT1900 maintenance philosophy is to undertake component repair and replacement at the  
Ascom Wireless Solutions Repair Department. Site maintenance is therefore limited to module  
replacement only. These modules are easily replaceable elements, like System Boards, Base  
Stations, fuses, Portable Telephones, desk chargers, etc.  
The main purpose of this section is to describe how a malfunctioning system’s faulty modules can  
be found and replaced, i.e. corrective maintenance. Furthermore, background information is given  
about the system’s internal diagnostic–and–test facilities to indicate the reliability and functionality  
of the Test and Maintenance software (see Chapter 2).  
Qualified Personnel  
Since maintenance is strictly reserved to qualified installation and maintenance engineers ONLY,  
persons who have not received instructions for accessing the equipment are not allowed to access  
the DCT1900 system. Any such actions will be considered as unauthorized access. Authorized  
access is restricted to engineers who are properly trained and certified by authorized DCT1900  
system trainers.  
1.2  
Preventive Maintenance  
Although preventive maintenance is not applicable to the DCT1900 systems, some words may be  
said about it:  
Wiring  
Accurate and secure installation of wires may prevent any future wiring failures, loose contacts,  
etc.  
Safety Requirements  
Whenever the system is being accessed, all ESD precautions must be taken. Do not touch boards  
without having yourself connected to the ground by a wrist–strap.  
Read Chapter 3, "Protection against Electrostatic Discharge" in Section 1, "Safety and Regulatory  
Information" in this manual.  
End–user Guidance  
End–users and customers should be fully aware of all DCT1900 features and the functionalities/  
features of the Portable Telephone. Informing end–users of how to operate the Portable Telephone  
and advising them to read the Portable Telephone User’s Guide may prevent many initial  
complaints.  
Configuration Back–up on Floppy  
Whenever something has changed to the system configuration (especially when passwords have  
been changed), a back–up of these changes should be made on a diskette using the "Save  
Configuration" function of the CSMW.

Maintenance, Test and Maintenance Software  
CHAPTER 2  
Test and Maintenance Software  
2.1  
Introduction  
The DCT1900 system has a powerful Test & Maintenance module incorporated in the system  
software. This software module regularly tests the entire system to locate possible faults in an  
early stage and to isolate the faulty circuits, thus minimizing the reduction in system service and to  
generate subsequent error messages and alarms. This chapter describes the functions of the test  
and maintenance software which are:  
z
z
z
Error handling (Paragraph 2.2)  
Testing (Paragraph 2.3)  
Resetting (Paragraph 2.4)  
Paragraph 2.2 gives an explanation of how T&M diagnosis verifies and eliminates faults and  
makes up a fault report.  
For a good understanding of this chapter, the following shall be noted (see Figure 2–1):  
z
Board Controllers  
BC are micro controllers, which control all communication between the various circuit boards  
and CPU. The SPU-S, CLU and the LTU have one board controller, the DTU and the SLU  
have two board controllers.  
z
Peripherals (P1..P8).  
Each board, except for the CPU and the DTU, has a number of peripherals, i.e. a number of  
identical circuits which act as a single device. The SPU has eight peripherals (SPCs) to handle  
eight calls. The LTU has 8 peripherals to which PBX line ports are connected to. A CLU/CLU-  
S has eight peripherals to which base stations can be connected. The SLU is a SPU and a  
CLU combined on one board, each with its own board controller, peripherals and board  
address. The DTU board has no peripherals but contains two identical circuits each controlled  
by a board controller and has subsequently two board addresses. The CLU, CLU-S, SPU,  
SLU and LTU peripherals are controlled by a board controller.  
z
Peripheral or board controller state.  
The state of a board controller or peripheral is identified as "new", "available", "malfunction-  
ing", etc. The actual state of such a circuit can be obtained by means of the CSMW software.  
For more information refer to the CSMW "Installer’s User Guide" Appendix I.

Error Handling  
The T&M software in the CPU is activated either on detection of operational faults, or when a test  
has to be executed. A description of tests that T&M can perform is found in Section 2.3. This  
section deals with fault handling.  
Operational faults and faults detected during tests will cause T&M to start up a fault handling  
procedure by which T&M tries to verify and clear the error. Figure 2–2 shows the different steps of  
the fault handling procedure. The two conditions for reception of a fault message cause the start of  
the flow.  
All messages received by T&M are stored in either the Info or the Fault table. Not all messages  
that are received are faults. Some are of the category "information only". In this case, the message  
is logged in the "Info" table with the status code L (logged). In all other cases, a message will be  
written in the "Fault" table, with another status code. When the message deals with a persistent  
fault the following occurs:

Maintenance, Test and Maintenance Software

z
An additional fault report will be written in a third table called "Service" table.  
A general alarm is raised.  
An alarm message is sent to the MS (Mobility only).  
A warning is generated by the CSMW software when running.  
Note:  
Red LED5 on the CPU board is on if there are messages in the "Info", "Fault" or "Service" tables  
that have not been read by means of the CSMW software.  
2.2.1 Diagnostics  
After T&M has concluded that the message is not an info but a fault message, T&M starts to  
decode, locate and verify the fault. This is done by the diagnostics module. After verification, T&M  
will isolate the faulty circuit to prevent usage by the system. This is done by changing its status  
temporarily to Test Mode (TME). When the fault cannot be verified, i.e. the fault cannot be found,  
the fault message in the Fault table will be completed with the status code C (cleared). This could  
indicate the occurrence of an intermittent fault.  
2.2.2 Fault Counters  
After verification of the fault, T&M knows exactly what type of fault occurred and where. A fault  
counter for this fault will be incremented. When the fault counter exceeds its threshold value, no  
further measures are taken, but immediately a GA will be activated with fault code 3 in the service  
table. The function of the fault counter is to count faults that can be cleared by maintenance, see  
Paragraph 2.2.3, but continue to re–appear, i.e. intermittent faults. When too many of these  
"intermittent faults" are counted within a specific time limit, an alarm shall be raised. The fault  
counter is halved every 24 hours to avoid generation of alarms when intermittent faults only occur  
occasionally.

Maintenance, Test and Maintenance Software  
2.2.3 Maintenance  
If the fault counter does not exceed its limits, T&M will now try to correct the error by resetting the  
circuit or board. This is called a T&M reset. This reset causes the circuit or board to start a self  
test. When the fault is cleared after this, the fault is intermittent. T&M will release the circuit by  
changing its state to AVE. In the Fault Table the fault message will be completed with the status  
code R (released).  
When the fault returns after the self test, the fault is persistent. T&M will take the circuit out of  
service by changing its state to malfunctioning, MFG, and raise an alarm. This alarm is called a  
general alarm. A general alarm will cause the following:  
z
z
z
The general alarm relay on the MCCB is activated.  
An alarm message is sent to the MS (Mobility only).  
A "system service required" window appears on the PC screen when the CSM software is  
running.  
z
z
z
A fault report is written in the service table.  
The fault message in the fault table is completed with the status code S (service).  
The faulty circuit or board is set to MFG.  
It should be noted that service is only required when a general alarm occurs. For those faults  
where a message is only written into the info and fault tables, no service is required because the  
system is not malfunctioning yet. The service table can be read out by executing the Select File -  
Create Service Report command. The error message in the table indicates the fault code, the  
malfunctioning board or circuit, its position in the system and a time–and–date stamp.  
2.2.4 Error Tables  
The three different error tables, as indicated above are:  
z
z
z
Info table  
Fault table  
Service table  
All tables have a size of 40 messages each. The info and fault table are cyclic buffers. The buffer  
always holds the last 40 messages. These two tables may never be cleared, except by a CPU  
reset or a system power down.  
The service table is a non–cyclic buffer. This means that when full, new error messages will not be  
logged. All service tables may be cleared by accessing the Clear Service Message command  
under System on the CSMW menu bar.  
All tables can be displayed by the Distributor–Diagnostics–Info–Error tables menu of the CSMW  
software.

Maintenance, Test and Maintenance Software  
2.3  
Testing  
The T&M module has three tests available to check the overall system performance and to report  
any deviations in performance. These tests are:  
z
z
z
Board power–on test  
Ack test  
24h test  
2.3.1 Board Power–on Test  
A board power–on test is an individual test performed on a board after power is applied to that  
board. The test is initiated not only after insertion of the board in an operational system, but also  
after a system power–on. When powering on the system, a board power–on test is executed  
simultaneously on all boards.  
The board power–on test has the following phases:  
z
z
z
z
Board test  
Board announcement  
Test result messaging  
Watch–dog test  
Board Test  
As soon as power is applied to the system or when a single board is inserted into a system under  
power, a self test is initiated on each board or on the single added board. This self test is under  
control of the board controller. During this board test, the board controllers and peripherals, if  
present, go through different states. The board test consists of:  
ROM/RAM test  
: All processors on the board start up a ROM/RAM test. The ROM’s  
check sum is verified and a read/write test is performed in RAM.  
: All board controllers test if they can communicate with the peripheral  
circuits on the board.  
Communication test  
Internal loop back test : A "speech–signal" is generated at one end of the board on a speech  
path and routed to the other end where a loop back is created, thus re–  
routing the signal to its originating point for verification. Thus, continuity  
tests are performed for all speech paths on the board.  
On the CLU and the CLU part of the SLU, the speech test is looped  
back by the Base Station thus testing the wiring to the Base Stations as  
well.  
State test  
: The various states that a board can be in are tested.  
DTU link test  
: For each DTC the primary rate communication link is checked.  
Board Announcement  
After completion of the board test, the board controller will set a message ready for the CPU. By  
means of this message the board will identify itself to the CPU. A polling processor on the CPU  
board will collect the message from the board controller of the board. By this board announcement  
the CPU knows the exact position of each board in the system. After the board announcement,  
the board controllers and peripherals will have the status: NEW.  
Test Result Messaging  
After the board announcement, the CPU requests the board to send the result of the board test.  
Upon the type of message received, T&M may decide to re–test a board and to make an error  
report. When the test results are positive, the board controllers and peripherals will be given a new

Maintenance, Test and Maintenance Software  
status AVE. Base Stations that are wired to the CLU/SLU and have power but have not been  
added to the system through the CSMW will get the status NEW. Erroneous boards or peripherals  
will get the status MFG.  
Watch–dog Test  
Board controllers have a watch–dog circuit which is periodically refreshed. The watch-dog circuit  
resets the controller when running in a loop. The watch–dog test is a test initiated by the CPU  
asking all controllers to test their watch–dog circuitry. The processor is forced to run in a loop, after  
which the watch–dog circuit should reset the processor again. The watch–dog on the CPU board  
is never tested.  
2.3.2 Ack Test  
The Ack test is a periodic test by which the CPU sends a message to all microprocessors in the  
system. Each processor shall respond with an acknowledgement. If a processor does not respond,  
an error is detected, and T&M will start a verification test. The test runs at a default setting every 2  
minutes. The Ack test does not interfere with system service. By means of the CSMW software the  
periodic running of the Ack test can be stopped or started and the test interval time can be  
changed by selecting System-Configuration-Automatic System Test.  
2.3.3 24–Hour Test  
The 24–Hour (24–H) test is a periodic system test that runs once every 24 hours. The test is  
similar to the power–on test, but all tests run under supervision of the CPU (T&M) instead of the  
board controllers. Excluded from the 24–H test are boards or peripherals occupied in call handling.  
T&M will wait for them to become free, while prohibiting new involvement in calls. These circuits  
will get status Test Mode AwaiTing (TMT). Circuits that are free from call handling are blocked  
immediately. Circuits that are being tested will get status TME.  
The system test reduces the system service noticeably. Boards or peripherals will be temporarily  
taken out of service during the test or while waiting to be tested. The test should therefore run after  
office hours. The default start time is 01:20 a.m. By means of the CSMW software, the start time  
can be changed, or the daily running of the 24 hour test can be stopped by selecting System-  
Configuration-Automatic System Test.  
2.4  
Resets  
In the DCT1900 system, different types of resets can be generated, each caused by different  
actions and with different results on reset counters and error tables. Table 2–1 shows the relation  
between action, reset type and result on counters.  
2.4.1 Reset Types  
CPU Power–on Reset  
A CPU power–on reset is generated when:  
z
System is switched on.  
z
CPU reset button is pressed.  
As a result a board power–on test is started by the entire system.

Board Power–on Reset  
A board power–on reset is generated when:  
z
z
z
System is switched on.  
CPU reset button is pressed.  
Board inserted in the system.  
As a result, the board power–on test is started on the board.  
Watch–dog Reset  
There are two different watch–dog resets: an expected and an unexpected. An expected watch–  
dog reset happens during the watch–dog test, which is the final test of the board power–on test.  
An unexpected watch–dog reset happens during normal operation when the CPU or the board  
controller is reset by their watch–dog circuit. A CPU watch–dog reset results in a restart of the  
system. A watch–dog reset from a board controller results in a power–on test for that board.  
Backplane Reset (SW)  
When the last board of a specific kind is not responding any more, the system cannot work or a  
minimum configuration error occurs. When one of the elementary functions is not available any  
more, the CPU will force the system to restart (power on test) to check what is wrong. Minimum  
configuration errors occur when:  
z
z
z
Last SPU-S is removed.  
Last DTU/LTU is removed.  
Last Base Station is removed. This can be caused by:  
-
The last CLU and the last SLU are removed.  
-
The last Base Station of the last CLU or SLU is removed, while still having CLUs or SLUs  
connected (connection of Base Stations is detected by the system).  
T&M Reset  
When T&M detects an error, it sends a reset to the appropriate board controller or peripheral to  
start up a local test. When the fault persists, an error message will be written in the service table  
and a general alarm is generated.  
When the fault is intermittent, there will be no error signalling to the outside world, but the error  
message remains in the Fault table and the absolute and relative reset counters are incremented.  
When the reset counter exceeds its threshold level, an error message is written in the service table  
and a subsequent alarm is generated.  
2.4.2 Reset Table  
In order to keep a reset–history, the CPU has a reset table where all resets are counted for each  
board. Also, resets to the various circuits on the CPU board are counted. The value of the counter  
in the reset table can be viewed by selecting System-Show Reset History in the CSMW.  
Two counter types exist for counting these resets: absolute counters and relative counters.  
Absolute Counters  
An absolute counter counts all resets since the associated board was placed in the system. This  
counter is cleared only at re–initialization or when the board is pulled out with a Replace/Remove  
action. Absolute counters have no threshold level.

Technical Product Manual - DCT1900  
Maintenance, Test and Maintenance Software  
Relative Counters  
A relative counter counts all resets since the power–on. The counter is cleared each time the  
power is cycled or at a CPU reset (button or watch–dog). Relative counters have a threshold level.  
When the threshold level is exceeded, a general alarm with fault code 3 is generated. Relative  
counter values are halved every 24 hours.  
Counters for CPU  
The CPU board has the following counters for CPU circuits:  
Absolute Counters:  
Power On reset  
Watch–dog reset  
: increments at every power on.  
: increments at every unexpected CPU watch–dog reset.  
Relative Counters:  
HSCX reset  
HDLC A reset  
HDLC B reset  
8031 (BC) reset  
: increments at every HSCX reset.  
: increments at every HDLC A reset.  
: increments at every HDLC B reset.  
: increments at every 8031 reset.  
Note:  
HSCX = High Level Serial Controller Extended  
HDLC = High Level Digital Link Control  
Counters for Board Controllers  
The CPU has the following counters for Board Controllers:  
Absolute Counter  
Relative Counter  
: increments on all type of resets, see Table 2–1.  
: increments at error (T&M reset/BC), increments at board insertion  
(backplane reset).  
Counters for Peripherals  
The CPU has the following counters for peripherals:  
Relative Counter  
: increments at error (T&M reset/P).

Maintenance, Fault Signalling  
CHAPTER 3  
Fault Signalling  
3.1  
Introduction  
This chapter describes how maintenance personnel or system managers are informed about faults  
in the DCT1900 system. Faults are signalled to the outside world in the following ways:  
General Alarm/Service Message  
System Screen of CSMW software  
Individual user complaints  
Common user complaints  
Alarms to MS (Mobility only)  
Furthermore, LEDs and the service display of the Portable Telephone are discussed. Although  
they cannot be taken as fault signaling devices, they can help diagnose faults.  
3.2  
General Alarm/Service Message  
When the CPU has classified a fault as "service" (persistent faults), a general alarm is raised, see  
Chapter 2, Paragraph 2.2. Upon a general alarm, a general alarm signal is activated and a "fault"  
report is written in the service table, which can be read by the CSMW software. The fault report  
indicates the type of fault, type of board, location and time and date. The format of a fault report  
and a list of fault codes can be found in Chapter 4.  
The local system manager or maintenance engineer is informed about a general alarm in three  
ways:  
General alarm signal  
"System Service Required" message on the PC–screen when the CSMW software is running  
Alarm message to the MS  
LED 5 on the CPU will also be turned on in the case of a general alarm. However, it may also  
be on as a result of an "info" or "fault" error table entry.  
General Alarm Signal  
The general alarm signal from a CPU is routed via the general alarm cable to the MCCB where it  
activates a general alarm relay. Via this make/break relay contact, a lamp or a buzzer or any other  
type of alarm device can be activated. The alarm signalling can be cleared by selecting from the  
CSMW menu bar System-Reset-Alarm Relay.  
"System Service Required"  
When the PC is running the CSMW software, a pop–up window containing the message "System  
Service Required" appears on the PC screen as soon as the general alarm is activated. If CSMW  
software is started after the occurrence of a general alarm, the "System Service Required"  
message will not appear on the screen. The general alarm signal is the only warning.  
Alarm Message  
When a fault is classified as "service" and posted in the service table, an alarm message is sent to  
the MS which enables remote monitoring of the operational state of a DCT1900 system. This  
capability is only applicable in the Mobility configuration.

3.3  
Checking Component Status through Cordless System Manager  
Checking radio  
Checking radio exchange components maybe done to verify fault reports from the service table or  
to check proper connection of base stations after installation. It is possible to check the status of a  
system board and its peripheral circuits in the Radio Exchange window of the CSMW. This screen  
is activated by checking the Radio Exchange selection under the menu bar option, View. Base  
Station status is viewed through the Base Station window by checking the Base Stations selection  
under the menu bar option View.  
Note:  
Red LED5 on the CPU board is on if there are messages in the info, fault or service table that have  
not been read by means of the CSMW software.

3.4  
Individual User Complaints  
Individual user complaints are received from only one user or, theoretically speaking, from two or  
more users who are not related to each other, for example being in different areas etc.  
Individual user complaints point to parts in the system that can only be accessed by that particular  
Portable Telephone. These parts are the Portable Telephone itself, the charger, etc. Unlike faults,  
for instance in Base Stations or system boards, which affect more than one user and mostly cause  
error reports, these types of faults cannot be detected by the system simply because of their  
nature. However, individual complaints are generally easy to trace.

Technical Product Manual - DCT1900  
Before any part of the system is suspected, it should be made clear that no handling faults have  
occurred. Typical handling faults are:  
Portable Telephone out–of–range, battery empty or Portable Telephone not switched on.  
"Hook flash" set on (if applicable), causing difficulties in going on or off hook.  
Audio and ringing volume too low.  
"Ringing" switched off.  
Improper handling of unit, damage due to dropping or inserting battery improperly.  
3.5  
Common User Complaints  
Common user complaints are similar complaints received from several users at the same time.  
Somehow these complaints have a common source and fault finding is based on finding that  
common aspect:  
Faults occurring in same area : A Base Station may be suspected.  
Blocking calls  
Lost calls  
: Lack of resources in SPCs (SPUs and/or SLUs) or air capacity.  
: During an inter system handover calls may get dropped due to  
an improper PWT air interface synchronization of the systems  
involved.  
3.6  
3.7  
Alarms to Mobility Server (DCT1900 Mobility Configuration Only)  
To inform the MS about its operational state, the DCT1900 system can send the following alarms:  
Alarm1  
Alarm2  
Alarm3  
: System start–up ready, system is available.  
: Non serious fault detected.  
: Serious fault detected. The general alarm signal is raised and a  
service message is generated. Also, it is possible that calls are  
not handing over to a base station because of improper time  
delay values. May relate to "fault occurring in same area."  
LEDs  
LEDs can be found on all system boards and Base Stations. Those LEDs may not and cannot be  
taken as alarm signalling devices because they are usually out-of-sight. However, sometimes they  
may give additional information to maintenance personnel.  
All system boards have four identical LEDs at the top, except the DTU board which has two rows  
of four LEDs. The CPU board is equipped with two extra LEDs. Base Stations have two LEDs. An  
explanation is given of those LEDs below.

Maintenance, Fault Signalling  
Fig 3–1 LEDs in the System  
3.7.1 LEDs on System Boards  
Each board has four LEDs at the top. The SLU has two times four LEDs because it consists of a  
SPU and a CLU on one board, each with its own board controller and board address. The DTU  
also has two times four LEDs because it contains a duplication of circuits with two board  
controllers, each with their own address.  
LED 1  
LED 1 is the "board powered" LED, illuminating when the board is powered. On all boards this  
green LED shall be on.  
LED 2  
LED 2 is the "watch–dog reset" LED, illuminating when the board controller receives a watch–dog  
reset. This LED normally only flashes during the power–on and 24–Hour test when the watch–dog  
circuit is being tested.  
LED 3  
LED 3 is the "board not polled" LED, illuminating when the board has not been polled by the CPU  
poll processor for a period of time. As a result the CPU may not know the board any more, giving it  
the state of PNP.  
LED 4  
LED 4 is the "error" LED, generally indicating an error on the board. On the CLU, the CLU part of  
the SLU board, and the DTU boards, this LED can be active for other reasons. Therefore, it may  
not always be taken as an error indicator.  
A CLU board or the CLU part of an SLU board will light LED 4 when Base Stations are in NEW  
state, which means that a delay value is not yet programmed. The LED will turn off automatically  
after programming the last Base Station of the CLU or if one Base Station is connected at a time,  
the LED will turn off when added via CSM.  
A DTU will light LED 4 when no trunk is connected. The DTU has no error, but the LED indicates  
that no external clock is detected. The LED turns off as soon as a trunk is connected.

3.7.2 LEDs on CPU  
The CPU is the only board having six LEDs. LEDs 1 to 4 are identical to the LEDs on other  
boards. LED 5 and 6 are found below the reset button.  
LED 5  
LED 5 on the CPU board is the "message–received–LED." When a message is written in one of  
the info, fault, or service tables, LED 5 is turned on. The LED is cleared immediately after reading  
the appropriate error table as it assumes that the reader then takes notice of the message.  
LED 6  
LED 6 on the CPU is the "T&M–active–LED." This LED turns on when the test and maintenance  
module is activated. This is the case when tests are executed, error messages are received or the  
error handling procedure is running, see Chapter 2, Paragraph 2.2. As soon as T&M is ready the  
LED is off. Because T&M does not run continuously, the LED often blinks.

Dynamic Channel Allocation (DCA) Display – Portable Telephone  
The Portable Telephones can be switched to DCA mode. In this mode the Portable Telephone  
displays information regarding the radio interface, like Base Station number, carrier, time slot  
number, RSSI, RQI, etc., while calls can still be made and received normally. The call indicator  
shows the user the hook status.  
Note:  
Activating the DCA mode reduces the normal functioning of the Portable Telephone. It is therefore  
recommended only to use this facility in exceptional cases, e.g. when service requires such an  
action.

3.8.2 Explanation of DCA Service Displays  
Data is always displayed in hexadecimal numbers. The Base Station number relates to the  
physical connection in the RE. Refer to Section 2, "System Description", Chapter 5, Paragraph  
5.4, "Numbering Conventions" in this manual to find this relation.  
Note:  
A Portable Telephone is always blind for the two adjacent time slots. For example, a Portable  
Telephone is locked on a Base Station on time slot 5. If it approaches a Base Station that has only  
one active channel (traffic or beacon) on time slot 4 or time slot 6, the Portable Telephone will not  
see that Base Station. The display remains unchanged until the current channel or the channel of  
the second Base Station changes. Consider this when using the menus below.  
Link Info

Fault Codes  
Table 4-1 shows all fault reports that may appear in the service table.  
Comment to the Table  
z
Column 1 - Fault numbers in sequence  
z
Column 2 - Service class:  
-
Class 1  
Faults in this class mean that communication with a board or peripheral is lost. In most  
cases there is a physical reason. Check on proper connection. Execute a Reset Board by  
the System manager–Control menu and check that the fault disappears. If not successful,  
proceed to class 3.  
-
-
Class 2  
Faults in this class can be minor faults that can be cleared by a board reset. Execute a  
Reset Board by the System Manager–Control menu and check that the fault disappears. If  
not successful, proceed to class 3.  
Class 3  
Faults in this class are in most cases fatal errors that require board replacement. It is  
recommended that you ensure that the fault is a hard fault by executing a Reset Board  
and checking if the fault disappears. If not successful, execute the Replace Board  
command from the System Manager–Control menu and replace the board with a spare  
board. The new board is automatically tested and taken into service. If the fault persists,  
call your local supplier for service.  
z
Column 3 - Fault threshold  
This column indicates the number of times a fault may occur intermittently. This means that  
after detection of the fault, the fault does not reappear when tested, see Paragraph 2.2. If this  
intermittent occurrence exceeds its threshold number within 24 hours, a status code S  
(service) will be written in the fault table, a fault report is written in the service table, and the  
general alarm is activated. The counter values are halved every 24 hours. Threshold value 99  
is equivalent to infinite.  
z
Column 4 - Fault description  
This column gives a brief description of the fault. In Paragraph 4.3.1 comments are given for  
some fault codes.

4.3.1 Comment to Fault Codes  
z
z
Fault 17 ... 26, 28, 29, 41  
CPU faults. Replacement of the CPU requires saving of its data  
to PC first by "System Manager-Save/Restore". If not possible  
any more, restore the new CPU with the most recent save file  
on disk (EEPROM.SAV and SPU_S.SAV).  
Fault 35, 36, 37  
These faults may disappear automatically. The DTU sends a  
message to T&M and T&M clears the fault status: L1 = AVE  
and L2 = AVE. However, the service error message remains  
and the general alarm as well. They must be cleared by "Clear  
Service."  
z
Fault 52  
Maintenance personnel must verify if the subject is operational  
or not. It may occur that a subject is given "AVE," but not  
working any more. If not working, reset the subject and wait for  
new fault message. If operational then simply wait to see if the  
fault reappears.

Maintenance, Part Replacement  
CHAPTER 5  
Part Replacement  
5.1  
General Rules  
z
z
Always protect yourself with a properly connected ESD wrist–strap before touching any board.  
Pack replaced boards immediately in ESD safe material. Use the packing materials from the  
replacement board.  
z
z
When sending a board in for repair, always include a printout of the corresponding fault report  
from the service table. If possible also include prints of info, fault and reset tables. Return the  
board together with a completed "RMA Form" (ask your service manager or distributor).  
Please observe that some CSMW software commands used in this chapter require a  
distributor privilege level.  
5.2  
Replacing a System Board  
All system boards, except the CPU, use the same board replacement procedure. There is no need  
to switch off the system when replacing boards, except for the CPU.  
Before replacing a faulty system board, the board must be set free from traffic. This is done by the  
Replace command. No new traffic is accepted, while existing calls can be terminated normally.  
These busy circuits will be blocked immediately after the call has ended. After the message "you  
can now replace the board," the board is set free.  
Procedure  
1. Select Board in Radio Exchange window by left clicking on the listed board.  
2. Right click and select Replace or choose Board-Replace from the menu bar.  
3. Choose if you want to wait for calls to terminate before execution.  
4. Wait until the message "you can now replace the board" appears on the PC screen  
5. Disconnect cables from board (mark their position!).  
6. Remove the board.  
7. Insert the new board in exactly the same position.  
8. Re–connect cables.  
9. Put the defective board in ESD bag and box.  
After insertion, the board will start its board–power–on test. After the test is finished, the board will  
be taken into service automatically.  
5.3  
Replacing the CPU  
If possible, back–up the contents of the EEPROM to the PC by selecting File-System Backup.  
The most "elegant" procedure is to make the system free of traffic before replacing the CPU board.  
This can be done by executing the System Manager–Control–Replace board command for all  
SPU and SLU boards starting at the board with the highest board number. When the last board  
"can be replaced," exit the CSMW software program. Also, let the users know that the system will  
be out-of-service before removing the CPU.

Procedure  
1. Switch off the system.  
2. Disconnect the cables from the CPU.  
3. Replace the CPU and re–connect the cables.  
4. Switch the system on.  
5. After LED 6 has turned off, start up the CSMW software.  
6. If the CPU has been initialized before with an incompatible version of the CSMW software,  
DCT1900 CSMW software will not start. If so, please contact your distributor.  
If the spare CPU is new, the CSMW will come up with the "Initialization" screen and the system  
shall be initialized with default data, e.g. by pressing only "Enter"–key.  
The EEPROM has to be downloaded with proper data from a previously "saved" file.  
7. Download the original system data from PC to EEPROM by selecting File-System Restore.  
5.4

5.5  
Expansion of Modular Cabinet System  
Expanding the Modular Cabinet system means that a new cabinet has to be interconnected to an  
existing cabinet. Modular Cabinets are interconnected in a fixed sequence. The correct cabinet  
sequence and all other details can be found in Section 5, "Installation Instructions," Chapter 4 in  
this manual.  
A special interconnection set is available to connect the cabinets. This set can only be mounted  
when a number of boards are removed at the side where the interconnection is to be made.  
Therefore, before starting, make a printout of the system screen of the current system to  
determine the current board positions and ensure that all cables are marked properly. Thus you  
can make sure that the current cabinet can be re–installed as it was. Ensure that you have an up–  
to–date back–up of the CPU data (save configuration) as well.  
Because a number of boards have to be removed from the current system, make sure that you  
have proper ESD safe boxes to put the boards in.  
Procedure  
1. Print out all board positions by the System Manager–Control–System command. Use the Print  
key (F7) and the Page–Down key.  
2. Save the EEPROM data, System Manager–Save/Restore-Save Configuration.  
3. Switch off the power of all cabinets, and disconnect battery and mains.  
4. Remove the front cover of the cabinet to which the new cabinet must be connected.

5. For the three slots farthest to the right, disconnect the cabling and remove the boards (the  
three slots farthest to the left if the new cabinet comes at the left side).  
6. Remove the break–out plate or conductive tape from the side panel adjacent to the new  
cabinet.  
7. Place the shielding gaskets from the interconnection set in the created hole with its springs  
outside, see Section 5, "Installation Instructions."  
8. Remove the brake–out plate or conductive tape of the new cabinet, at the correct side, and fit  
the shielding gaskets.  
9. Mount the new cabinet to the wall. Keep a distance of .3" to the adjacent cabinet.  
10. Feed the flat cable through the hole and connect it to the backplane connectors on both sides.  
11. Secure the new cabinet to the wall by the retaining screws.  
12. Remove the R–networks from the backplane of both cabinets, at adjacent sides (see Section  
5, "Installation Instruction," Chapter 4, "Modular Cabinet.")  
13. Interconnect the ground strips of both cabinets using the protective ground cable.  
14. Re–install the boards and cabling of the "old" cabinet.  
15. Install the new cabinet according to Section 5, Chapter 4, "Installation Instructions" in this  
manual.  
The easiest way to install a Modular Cabinet’s cabling is to put the cabinet on its back on a desk.  
5.6  
Re–positioning Boards  
The CPU keeps initialization data of all boards in its memory. This data is related to the board  
position. If the procedures below are maintained, no initialization data will be lost and significant  
time on re–configuring a system can be saved.

Maintenance, Fault Finding Procedures  
CHAPTER 6  
Fault Finding Procedures  
6.1  
Introduction  
These fault finding procedures are designed to help maintenance personnel locate and eliminate  
faults in the shortest possible time. The fault finding extends to the level of a replaceable part  
(DTU, SPU, power supply unit, etc.). Although cabling and connection errors are not covered,  
suggestions will be given to check these items when the fault is presumed to be introduced by  
them. The basic assumptions for the fault finding are:  
z
z
z
Only one fault at a time.  
The fault is persistent (not intermittent).  
Fault is not due to cabling or bad connections.  
The execution of the following steps will avoid unnecessary fault finding:  
z
Analysis of the fault symptoms.  
z
Visual inspection of the system (cabling, connections, power cords).  
If these steps do not solve the fault, the flowcharts given in Paragraph 6.4 can be used.  
6.2  
Symbols used in the Flow Charts  
Question  
1
This symbol contains a question with two or three possible  
answers being "Yes", "No", or other Text.  
4
Question?  
2
Inputs are points 1 or 4 and outputs are points 2 or 3 or 4.

Instruction  
References  
This symbol contains an instruction for the maintenance  
engineer.  
This symbol is used as a starting point for a procedure (e.g.  
START), as a reference to another flowchart, or to end a  
procedure (END).  
This symbol is used as a reference within one flowchart. This  
can be to a part of the flowchart on another page (e.g. A or B)  
or to a part of the flowchart on the same page (e.g. 1).  
Flow  
Arrows indicate the normal flow.

How Defective Items are Indicated  
When the flowcharts lead to a possible cause, this is indicated by a statement giving the name of  
the defective part or the cause of the problem, e.g. a defective SPU board is indicated by the  
statement “SPU.” When there are more possible items, they are listed in order of decreasing  
probability.
