Controls and Connections
front view
1. POWER indicator
The POWER LED lights when the DTI 2000 receives power input from the supplied power supply
unit, which allows worldwide connection and use because it accepts input voltages between 85V
AC and 250V AC.
2. SEIZE / DROP key (SELECT)
This key allows manually accepting or cancelling phone calls and is mostly used for testing. When
an incoming phone call is present (ringing), pressing the SEIZE / DROP key establishes the
connection (picks up). Pressing the SEIZE / DROP key again cancels (hangs up) a live connection.
Since the DTI 2000 automatically picks up any incoming call respectively automatically hangs up
when the remote call is terminated, this key is basically not needed during normal operation.
3. DROP and SEIZE indicators
The red DROP LED indicates that there are no live connections (i.e. the DTI 2000 is on-hook).
The green SEIZE LED indicates that the DTI 2000 established a connection to the calling party
(i.e. the DTI 2000 is off-hook). The DTI 2000 automatically connects to incoming phone calls.
Using the internal DIP-switch S202 allows specifying the number of rings prior to accepting a call.
4. TALK indicator
The orange TALK LED lights whenever the DTI 2000 is in announcement mode (i.e. when an
announcement into a single or several zones of the PA-system has been initiated via telephone
connection).
5. LEVEL control / meter bars
Audio signals that are transmitted from the DTI 2000 to the DPM 4000 System Manager can be
monitored using the TO PAGING MANAGER meter bar. Level adjustment is possible via the
associated LEVEL control on the front panel using a small screwdriver. The level setting range is
between ***dB (counter clockwise stop) and ***dB (clockwise stop).
Currently, the TO TELEPHONE indicator and the associated level control are not used.

6. TO PAGING MANAGER connectors, female
The two TO PAGING MANAGER connectors represent the interface to the DPM 4000 System
Manager. Using either the 9-pole D-Sub connector or the 6-pole RJ-12 socket (simultaneous use
of both terminals is not possible) to establish audio and data connection to the DPM 4000 is
possible. The DTI 2000 needs to be connected to one of the paging console inputs (DPC IN, RJ-45
socket) on the DPM 4000. The needed interface cable (RJ-12 to RJ-45) with a length of 3.5m is
supplied.
7. DATA indicator
The DATA LED indicates that data is being transmitted between DTI 2000 and DPM 4000
System Manager. Therefore, it serves as main monitoring indicator for correct data connections.
8. DIP switch for address and operation mode settings
The DTI 2000 allows setting an address between 1 and 16. CAUTION: Make sure never to
connect two or more appliances with identical address settings to the DPM 4000 System Manager,
since this would inevitably result in data conflicts. This also includes the address settings of the
connected paging consoles.
Please refer to the chapter DIP-switch settings for further details.
9. Phone sockets
Two telephone connectors are located on the rear panel of the DTI 2000. Connect the PHONE
LINE socket with your telephone wall outlet. The LOOP THRU socket offers connection for a
telephone set.
10. POWER SUPPLY connector
Connect the supplied power supply unit to this connector by inserting the round plug of power
supply unit into the POWER SUPPLY socket on the rear panel of the DTI 2000. Turn the plug’s
locking ring in clockwise direction to establish a reliable connection. Afterwards, connect the
supplied mains cord to the power supply unit before inserting the mains plug into a mains wall
outlet.

2. DIP switch settings
The DTI 2000 provides a single DIP-switch on the rear panel and two internal DIP-switches.
Theses switches are meant for making specific basic settings, which have to be made before
operating the appliance for the first time. Generally, no changes need to be made during the later
operation.
2.1 DIP switch for address and operation mode settings on the rear panel (S201)
A switch is “OFF” when it is set to its upper position. Consequently the ON-position is down.
The following table shows how to set addresses using the switches 1 – 4:

2.2 Internal DIP switches (S202 and S203)
To make any changes to the internal DIP-switch settings, you first have to remove the cover plate
by loosening/removing the screws on the rear panel, as indicated in the diagram below.
Remove these screws
Loosen these screws
Slightly lift the cover plate at the rear and remove it. Now you are able to change the DIP-switch
settings.
For installing the cover plate back in place, first position the case top in the guidance slots of the
case bottom and slide it in as far to the front until it rests in place. Put the screws back in place and
tighten them. Do not forget to tighten the previously loosened screws.
The following picture shows the positions of DIP-switches S202 and S203:
Internal DIP-switch S202
Internal DIP-switch S203
DIP-switch S202 allows setting the ring count, which controls the number of rings before the DTI
2000 automatically picks up and establishes a connection. To change the ring count use the
switches 1 - 2. The DTI 2000 is factory pre-set to accept an incoming call after one ring (SW1 &
SW2 = OFF).

Switches 3 – 8 are not used and should be left in their OFF-position.
The setting of DIP-switch S203 determines the timeout of a connection (i.e. before the DTI 2000
automatically hangs up). This ensures that phone line and PA-system are not blocked any longer

than the specified maximum connection timeout setting allows. If the caller does not enter any
new selection during the connection timeout, the DTI 2000 automatically finishes the momentary
announcement and releases the PA-system. Afterwards, the telephone connection is disconnected
as well.
Switches 1 – 4 are used to set the maximum timeout for a connection as indicated in the following
table:

CAUTION:
The DTI 2000 is factory pre-set to a
maximum connection timeout of 1.5
minutes (SW1 = OFF, SW2 = ON, SW3 =
ON, SW4 = OFF).
Setting the switches 1 – 4 to their OFF-
position specifies an infinite timeout, i.e. the
connection is not automatically
disconnected.
Switches 5 – 8 are not in use and should be left in their OFF-position.
3. Rack installation
There are two rack-mounting options for the DTI 2000. Use the MCP-2 rack installation kit for
installing a single DTI 2000 and the MCP-1 for installing two units next to each other in a rack
system. The following diagram shows both options.
4. Connections
4.1 Connecting the DPM 4000 System Manager

Download from Www.Somanuals.com. All Manuals Search And Download.
Use one of the TO PAGING MANAGER sockets (not both simultaneously) for connecting the
DTI 2000 to the DPM 4000. The DTI 2000 needs to be connected to a paging console input (DPC
IN, RJ-45 socket) of the DPM 4000 using the supplied, 3.5m long interface cable (RJ-12 to RJ-
45). The following diagrams show the pin-assignment of sockets and cables. The LED labelled
DATA is located next to the sockets. This LED lights during active data transmission between
DTI 2000 and DPM 4000 System Manager providing indication of a correct connection.
TO PAGING MANAGER connector’s pin-assignment
Interface cable RJ-12 / RJ-45
4.2 Connecting Phone Lines or a Telephone set
Two phone connectors are located on the rear panel of the DTI 2000. Connect the PHONE LINE
socket with the telephone wall outlet. The LOOP THRU socket provides a connection facility for
an optional telephone set.
NOTE: The LOOP THRU signal is disconnected whenever the DTI 2000 picks up a phone call via
the PHONE LINE socket.
4.3 Power Supply
Insert the supplied power supply unit’s round plug into the POWER SUPPLY socket on the rear
panel of the DTI 2000. Turn the plug’s safety lock clockwise to establish a securely locked
connection. Afterwards, connect the supplied mains cord to the power supply unit before inserting
the mains plug into the mains wall outlet. The DTI 2000 is immediately operational upon
establishing accurate connection.
5. Adjusting the Audio Level
Adjusting the level of the audio signal that is transmitted to the DPM 4000 System Manager is
possible via the LEVEL TO PAGING MANAGER trimmer. Doing so, use a small, flat
screwdriver to first set the trimmer to its centre position. Call the DTI 2000 and speak with a
normal voice into the receiver while adjusting the audio signal level for best transmission quality.
The level meter should not indicate any signals in the red area.
The TO TELEPHONE indicator and the corresponding control are not currently used.

6. Country settings
Different countries and regions have different telephone standards, which may differ in e.g. signal
level and dial tones. The DTI 2000 can be and should be configured to meet those individual
requirements. Not doing so can result in faulty operation of the DTI 2000.
Generally, the DTI 2000 is factory pre-set prior to shipping. In case of problems, please contact
the nearest service-centre or the technical support.
Operating the DTI 2000
First, make sure that the DTI 2000 has been correctly installed and connected, as described before. Be
sure to check the address and DIP-switch settings.
The DTI 2000 has a Default Configuration, which suits most standard applications. Custom
configuration of the DTI 2000 is possible using the PC Designer Software, which is explained in detail
in the chapter “Configuring the DTI 2000”.

No meaning in the DTI 2000
The DTI 2000 decodes all DTMF dial tones as well as signal tones for the recognition of incoming
phone calls, pressed keys and determination whether a connection has been dropped or if the calling
party hung up. Each one or two-digit number between 0 (00) and 99 represents an individual function,
which is assigned in a calling numbers table (either in the Default Configuration or via user
configuration). Three or four-digit numbers are used for entering passwords. The asterisk (*) and hash
mark (#) keys offer special functions; e.g. as separator, for clearing faulty entries (Clear), as talk
button, or to drop a connection.
1. Telephone call to the DTI 2000
Simply dial the number of the telephone line to which the DTI 2000 is connected. You are
presented either with a ring signal when the line is not busy, or otherwise with a busy signal when
the line is already busy. After the specified ring count (refer to DIP-switch S202) the DTI 2000
DTI 2000 Manual e EDITED.doc

accepts the call and establishes a connection. First, you will hear a short noise (DTI 2000 line test)
followed by different tone signals, which indicate that the DTI 2000 expects further entries.
2. Password Entry
The DTI 2000 answers an incoming phone call with different tone signals, depending on its actual
status. When not password-protected, a single tone signal indicates that the DTI 2000 is ready to
accept a function command (via entering a one or two-digit function number). If protected b a
password, the appliance answers incoming calls with a two-tone signal. Entering the password for
the desired access level is necessary. To enter access level 1 you have to enter a three-digit
password, for entering access level 2 a four-digit password is needed. While level 1 only provides
access to zone and group selection plus launching announcements via the * key, level 2 allows
accessing all functions (announcements, text message playback, macros, stop, etc.). After entering
the correct password, the DTI 2000 acknowledges a request with a single tone signal. The DTI
2000 sends a two-tone signal when entering the wrong password. After entering the incorrect
password three times in a row the DTI 2000 drops the connection.
3. Zone / Group Selection and Announcements
Once the DTI 2000 is ready to accept a command (indicated by a single tone signal) and access
level 1 (or 2) has been activated, selecting a single or several zones, groups or the ALL-group and
then making an announcement in the selected areas is possible. Selecting a single zone, group or
ALL is possible through entering the one or two-digit code that represents the according selection
function in the call number table. Selecting further zones / groups is possible by using the hash
mark key (#) as a separator before entering the next number, and so on. Numbers not representing
a selection or clear-function are ignored. Announcements are initiated via the asterisk key (*). The
DTI 2000 indicates with a single tone signal that a selection has been made and that you can start
making your announcement. A “Low Busy” signal (two-tone sequence – tones with different key)
indicates that one or several low priority zones are busy. It is your decision whether you want to
wait (enter #), or to interrupt the current announcement (enter * once again). A “High Busy” signal
(rapid, high-pitch sequence of tone signals) indicates that one or several high priority zones are
busy. Once the announcement is finished, you can enter an announcement end mark through using
the hash mark key (#). The connection is not dropped, which enables you to select new zones or
groups for making further announcements. Pressing the asterisk key after an announcement is
finished drops the connection – the DTI 2000 “hangs up”.
4. Direct Call
The DTI 2000 allows making announcements in permanently pre-selected zones or groups (Direct
Call). This function can only be accessed from access level 2. No other number selection is
accepted if the selected one or two-digit number represents a talk function. Press the asterisk key
(*) to launch an announcement. The DTI 2000 acknowledges this request with a single tone signal,
indicating that it is operational and ready to accept your announcement. The DTI 2000 outputs a
“High Busy” signal when one or several high priority zones are busy. After the announcement is
finished, pressing the hash mark key (#) allows selecting other functions. Using the asterisk key
(*) drops the connection.
5. Text Playback
The DTI 2000 offers the ability to playback pre-recorded text messages in permanently pre-
selected zones. This function can only be accessed from access level 2. No other number selection
is accepted if the selected one or two-digit number represents a text message function. Press the
asterisk key (*) to launch text message playback. The DTI 2000 acknowledges this request with a
single tone signal, indicating that it is operational and ready to accept desired function command.
DTI 2000 Manual e EDITED.doc
10
Download from Www.Somanuals.com. All Manuals Search And Download.
The DTI 2000 outputs a “High Busy” signal when one or several high priority zones are busy. A
tone-sequence indicates that a text message is being played back. Text message playback normally
stops automatically but manually stopping the function is possible as well by entering the STOP-
function number code (default setting = 0 respectively 00).
6. Macros
The DTI 2000 allows launching macros that are programmed in the DPM 4000 System Manager,
thus providing access to special functions. For example: switching relays, starting and stopping
signals, entering parameters, launching test sequences, and many others. The macro function can
only be accessed from access level 2. No other number selection is accepted if the selected one or
two-digit number represents a macro function. Pressing the asterisk key (*) launches a macro. The
DTI 2000 acknowledges this request with a single tone signal, indicating that it is operational and
ready to accept desired macro command. It sends a two-tone signal, when entering an incorrect
command or if there is any other problem.
7. Cancelling a Function (Break)
Cancelling an announcement is possible using the hash mark key (#) (Break). The current zone
selection is cancelled as well, while the connection to the DTI 2000 is not interrupted. The
appliance acknowledges the request with a single tone signal and it is ready for new entries (a new
zone selection, launching text message playback, triggering macros).
The hash mark key (#) can also be used to clear erroneously made entries. Using the hash mark
key (#) directly after selecting a text, announcement, macro or stop function prohibits the function
from being executed, but erases it instead. The DTI 2000 is ready for new entries.
8. Hang Up / Cancelling a Connection
Using the asterisk key (*) directly after making an announcement or pressing the hash mark key
(#) forces the DTI 2000 to drop the connection and “hang up”. The DTI 2000 also interrupts the
connection when the calling party hangs up. However, in that case, a few busy tone signals are
output via the PA-system, which can be rather disturbing. Therefore, dropping the connection
through the use of the asterisk key (*) is always preferable.
The DTI 2000 can also be configured to automatically drop a connection after a definable period
of time. This is especially useful to prevent the PA-system from being blocked by a telephone
announcement over longer periods or that it is constantly blocked because of malfunction or faulty
connections. The period of time after which the DTI 2000 automatically drops a connection can be
set in a range between 20 seconds and 10 minutes via the internal DIP-switch S203.
Configuring the DTI 2000
The PC Designer software allows custom configuration for the DTI 2000 to match any specific
application. The programming procedure is equivalent to configuring a paging console. Programming
a paging console’s function keys relates to the programming of a call number table for the DTI 2000.
This table holds the assigned functions of up to 100 one or two-digit numbers (0 to 99). The buttons 1
to 99 on a console correspond to the call numbers and the table entries 1 to 99. The 100-key represents
the call number or table entry 0 (respectively 00) and, as standard, another entry in the table is
reserved for the talk function, which can be activated from a telephone set using the asterisk key (*).
Using a DPC 4550 + DPC 4350 paging console in the PC Designer software for configuring the DTI
DTI 2000 Manual e EDITED.doc
11
Download from Www.Somanuals.com. All Manuals Search And Download.
2000 is recommended, because this is the only way to gain access to the total amount of 100 call
numbers (accordingly to 100 paging console keys).
Connect a DPC 4550 + DPC 4530 to the corresponding input at the DPM 4000 in the PC Designer
Software, give it a meaningful name (e.g. telephone interface), and open the paging console dialog
with a double-click on the paging console icon.
The paging console dialog allows assigning one of the following functions per each call number (0 ...
99) respectively for each entry in the table:
1. Disabled:
The call number #nn has no function.
2. Stop:
Stops the actually active audio signals (chime, text message playback, alarm) depending on the
programmed stop function and priority.
3. Clear:
Clears the actual zone or group selection.
4. Select:
This function selects a zone, group (groups may include up to 100 zones) or all zones (collective
call) for an announcement or text message playback.
5. Text:
This function starts text message playback in permanently pre-selected zones or groups or in the
actual zone selection. Assigning priorities is possible.
6. Talk:
This function starts an announcement in selected zones or groups. It also provides the possibility
to initiate a collective call in all zones. A permanently assigned zone or group as well as the actual
zone selection can be defined as a target. Assigning priorities as well as programming a pre-chime
signal is possible.
A special entry in the table is reserved for the standard talk function (corresponds to the talk
button #108) , which can be activated from a telephone set using the asterisk key (*).
7. Macro:
This function starts a macro via its pre-defined macro number, which of course is only possible
when a corresponding macro has been programmed in the DPM 4000.
A typical call number table might look like that:

Setting the DTI 2000’s password codes is possible in the general paging console dialog. The two
access levels have individual passwords. The default password settings are 111 (3-digit for user level
1) and 2222 (4-digit for expert level 2). Access level 1 only allows zone / group selection and making
announcements through the use of the asterisk key (*) while the expert level 2 provides access to all
functions (announcements, text message playback, macros, stop, etc.). Password-protection is inactive,
so that anybody has access to the functions of the corresponding level, when entering “0” as a
password.
In the DTI 2000, the attributes microphone compressor, tone signal and German date have no function
and should be left at their default setting.

Test Functions
The processor system automatically runs an initial self-test whenever the DTI 2000 is connected to the
mains. During this procedure, first the red DROP LED should light. Afterwards, the orange TALK
LED blinks for approximately 3 seconds. In case faulty operation is being recognized, the processor
system stops and the DROP and TALK LEDs light. Otherwise the DROP LED is dimmed and only
the red DROP LED lights as long as a telephone connection has not been established.
Pressing the SEIZE / DROP button on the front panel manually establishes a connection (pick up) or
drops a connection (hang up). When the button is used to “take a call”, the green SEIZE LED should
light and the red DROP LED should be dimmed. Pressing the key once again drops the connection and
the red LED lights while the green LED is dimmed.
The orange TALK LED lights when the DTI 2000 is in announcement mode (i.e. when a telephone
announcement in a single or several zones of the PA-system has been activated).
