* The ringer equivalence number (REN) is useful to determine the quantity of  
devices that you may connect to your telephone line and still have all of those  
devices ring when your number is called. In most areas, the sum of the RENs  
of all devices on any one line should not exceed five (5.0). To be certain of  
the number of devices you may connect to your line, as determined by the  
REN, you should call your telephone company to determine the maximum  
REN for your calling area.

in the Master AUX1, and one MFR is installed in the Slave AUX1. With Cable Kit Version  
1.2, both MFR cards are installed in the slave cabinet--one in the CPC slot and one in AUX1.  
(See page 6-10 for instructions on installing MFR cards in double-cabinet systems.)  
2. The API card is installed in AUX1 only when a CBL card is used.  
3. Part VB-43110 includes both the CBL-M and CBL-S cards, as well as the required connect-  
ing cables. CBL-M is installed in the master cabinet, CBL-S in the slave cabinet.

Processor Description  
DBS call-processing is controlled by the Call Processor Card (CPC). Four  
CPC models are available: CPC-A, CPC-B, CPC-AII, and CPC-EX. For a  
complete list of hardware enhancements available with the CPC-B, CPC-AII,  
and CPC-EX, please see Appendix A and Appendix B, located in the back of  
this manual. See the Appendix in Section 700 - Feature Operation for a  
complete list of feature enhancements associated with each of these CPCs.  
In most cases, the features provided with the DBS depend on the model and  
software version of the CPC. However, the availability of some features also  
depends on the model and version of the Service Circuit Card (SCC).  
The following table shows some of the major differences between CPC/SCC  
features. Other differences are noted throughout this manual when they apply  
to specific installation instructions. For more details on the features provided  
with each processor, see Feature Operation, Section 700.

Test Phone  
Guidelines  
• The test terminal (CN3) on the DBS Connector Panel can be used to  
connect a display phone for programming.  
The test terminal can be used for initial programming before extension  
cabling is completed.  
• The test terminal is turned on by flipping SW1 on the Connector Panel to  
the “Test” position. When SW1 is in the test position, extension ports 7  
and 8 are connected through the test terminal. When SW1 is not in the test  
position, extension ports 7 and 8 are connected through the MDF.  
Note: Before using the test terminal on a DBS that is operational, be sure  
the phones connected to ports 7 and 8 can be taken out of service.  
• A DSS/72 can be connected to the display phone for text entry. Port 7 must  
be assigned as extension 101 and the DSS/72 must be assigned as  
telephone type 13 for the DSS/72 to operate.  
Installation  
1. Connect the telephone and DSS (optional) to CN3 on the Connector  
Panel. (See Figure 3-18 on page 3-19.)  
2. Set SW1 to “Test.”  
3. When programming is completed, set SW1 back to “ST.”

page 4-44.  
• For pinouts and color codes for the main trunk connector, see Table 4-2 on  
page 4-5.  
• Each circuit on the ground-start trunk card can be used as either a loop-  
start or ground-start trunk. By default, all circuits on the ground-start trunk  
are assigned as loop start.  
• The ground-start trunk card requires CPC-B Version 1.0 or higher.  
• The DID card requires CPC-B (Version 2.0 or higher) and SCC-B  
(Version 1.2 or higher).  
• Both ground start and DID trunks require an external -48V floating output  
power supply. The following table shows -48V power consumption for  
one- and two-cabinet systems.

Connect the test set across the tip and ring of the trunk to be tested. With  
the test set in the “monitor” position, apply ground to the ring side of the  
trunk.  
If you hear dial tone, the polarity of the trunk is okay, and you can switch  
the test set to the “talk” mode to test the voice path.  
If you do not hear dial tone, ground the tip side of the trunk. If you  
receive dial tone when grounding the tip side, polarity is reversed.

naling, an MFR card is not required.  
3. SCC-B with ROM 1.3 or later is required if the central office does not provide T1 dial tone.  
4. Version 1.2 of the Cable Kit is required for T1.  
• The T1 trunk card must be installed in the “EC/TRK” slot.  
• The installer must provide a Channel Service Unit (CSU) that complies  
with FCC Part 15 and Part 68. The CSU is installed between the DBS and  
the public network. The CSU provides alarm, diagnostic, and monitoring  
functions, as well as network protection.  
The CSU must be compatible with the framing format (SF or ESF) that is  
provided by the public network.  
Maximums  
• One T1 card can be installed per cabinet.  
• The number of T1 cards that can be installed in double-cabinet systems  
depends on the sizes of the connected systems. Table 4-12 on page 4-15  
shows T1 maximums for double-cabinet systems.  
Note: The DBS 72 + DBS 40 combination does not support T1.

• Fractional T1 can be used when fewer than 24 T1 trunks are needed.  
Fractional T1 allows you to use only a portion of the 24 channels provided  
on the T1 card.  
• Though each T1 Interface provides 24 trunk channels, T1 trunks do not  
increase the overall trunk capacity of the DBS. Each T1 channel subtracts  
from the total number of analog trunks that can be installed.  
• With CPC-B earlier than 5.00, the number of analog trunks that can be  
used with Fractional T1 are always decremented in quantities of 8.  
For example, if you are installing a T1 in a DBS 96 and you only want to  
use 12 T1 channels, the logical number of analog trunks that would be  
available is 20 (32 - 12 = 20).  
The number of analog trunks must be decremented in quantities of 8, the  
actual number of analog trunks that can be used is 16:  
(32 total trunks - 16 (two 8-trunk increments) = 16.)  
Tables 4-9 through 4-11 show the possible combinations of analog and  
digital trunks assignments based on system size.  
The trunk numbering shown in these tables is determined by backplane  
trunk port assignments. Therefore, the numbering cannot be changed.  
• With CPC-B 5.00 and higher and the VB-43511A Loop Start Trunk Card,  
the number of analog trunks that can be used with Fractional T1 are  
decremented in quantities of 1.  
Note: Analog trunks are numbered beginning with “1.” T1 trunk channels  
are numbered beginning with the highest trunk channel used.

• Programming is not required to associate trunk ports with slot locations.  
However, you must use programming to specify that a combination of T1  
and analog trunks are installed, and you must also specify how many T1  
channels are used.

Installing a T1 in a Single Cabinet  
The following instructions explain how to install a T1 in a single-cabinet  
system. These instructions also apply when a T1 is installed in only the  
master cabinet of a two cabinet system.  
If only one T1 is installed in a two-cabinet system, it must be installed in the  
cabinet specified in Table 4-8 on page 4-13.  
Note: The T1 Interface cannot be used for systems consisting of a DBS 72  
connected to a DBS 40.  
1. Check connector 4 (CN4) on the Sync Unit (VB-43563). Make sure that  
Pins 2 and 3 are strapped. (See Figure 4-5.)  
When Pins 2 and 3 are strapped, the Sync Unit synchronizes the DBS T1  
card with the signaling provided by the public network.

Extension Connectors  
The number of extension ports that can be connected to your system depends  
on the type of system you have. Figure 4-13 shows the maximum number of  
extensions that can be connected to each system when the extension  
expansion connector is used.  
Table 4-1 summarizes the number of ports that can be used without the  
extension expansion connector. Chapter 6 includes extension maximums for  
two-cabinet systems.

Analog Extensions  
Note: Normally analog extensions are supported using the AEC (VB-43621).  
Alternatively, a Single Line Telephone Adaptor (SLTA, VB-43709) may be  
used to support analog DTMF (2500 set) extensions. The SLTA converts up  
to 4 digital ports to analog ports. See “Single Line Telephone Adaptor” on  
page 5-34 for more information.  
Guidelines  
Installation  
• An MFR card (VB-43431) is required when the AEC is used. The MFR  
card, which provides DTMF signals, includes eight circuits that are shared  
among the analog extensions.  
• The AEC also requires the SLT ringer box (VB-2089P).  
1. Install the AEC cards in extension slots.  
2. Install the MFR card in AUX1 or AUX2. If installing in a two-cabinet  
system, see Chapter 6 for specific information for installing MFR card(s).  
3. Install the SLT Ringer Box as shown in Figure 4-14. Be sure to note the  
differences between the DBS 40 Connector Panel and the Connector  
Panel on the DBS 72 and 96.

Digital Extensions  
The following instructions explain how to connect digital extensions. These  
instructions apply for key phones and Digital Single-Line Telephones  
(DSLTs). Special instructions are provided for installing the DSS/72 and  
EM24 terminals, which connect to digital phones.  
1. Install the DEC cards in extension slots.  
2. Use a standard 50-pin cable to connect the extensions from the MDF to  
the appropriate extension connector, as shown in Figure 4-13 on page 4-  
31. (Refer to Tables 4-20 through 4-22 for extension pinouts.)  
3. If you are installing a DBS 40, attach the EMI filter to the amphenol  
cable, as shown in Figure 4-15.  
DSS/72  
Guidelines  
• The DSS/72 (VB-43320) is a 72-key console that can be attached to the  
attendant phone. It provides direct station selection and busy lamp fields  
for internal lines. The DSS/72 can also be used for text assignment.  
• When the attendant feature package (VB-43330) is installed (CPC-B  
Version 2.0 to 4.0 only), the DSS/72 can be used as an Attendant Console.  
The Attendant Console provides station monitoring and call transfer by  
name for large systems, even if a large display phone is not used. For a  
detailed description of the differences between the standard DSS/72 and a  
DSS/72 configured as an Attendant Console, see Feature Operation,  
Section 700. For instructions on using the Attendant Console, see the  
Attendant Console User Guide, Section 760.  
• Up to two DSS/72s or one Attendant Console can be assigned to attendant  
phones 1 and 2. Attendant phones 3 and 4 can each have one Attendant  
Console assigned, but neither can have a DSS/72.  
• If more than one DSS/72 is assigned to an attendant phone, only one of the  
DSS/72s can be cabled from the same wall jack as the attendant phone.  
Additional DSS/72s must be cabled from separate wall jacks.  
• The DSS/72 comes with a mounting bracket, screws, and a two-conductor  
cable for attaching the DSS to the key phone.

Remote Administration Interface (RAI)  
Guidelines  
• The RAI is a modem card that installs on the SCC card. The card is used to  
remotely administer the system through a trunk line.  
• Two versions of the RAI card are available. Both versions use 1 Stop bit, 8  
data bits, and no parity. The RAI-A card has a fixed baud rate of 300. The  
RAI-B card supports both 300 and 1200 baud operation. The following  
table shows the transmission rate of each card along with the SCC version  
compatibility.

Installation  
• Remove the upper cover of the SCC card.  
Jumper 1 (J1) on the RAI-B controls the transmission rate. When closed,  
the transmission rate is switchable from 300 bps to 1200 bps through  
system programming. When open, the rate is fixed at 300 bps.  
• Connect the RAI card to the connector on the SCC card.  
The RAI-A connects to CN3. RAI-B connects to CN2 and CN3.  
• Replace the upper cover of the SCC.  
Note: To adjust the output level of the RAI, set switch 4 as shown in  
Figure 5-3.

Background Music/Music-On-Hold  
Guidelines  
• A single music source can be used for both background music (BGM) and  
music-on-hold (MOH), or separate music sources can be used for each  
feature.  
• If a single music source is used for both MOH and BGM, the music source  
connects to CN5 on the Connector Panel. If separate sources are used, the  
MOH source connects to CN5, and the BGM source connects to the BGM  
connector on the SCC card.  
• If an FM radio is connected to the BGM connector on the SCC, install it at  
least 16.5 ft. (5m) away from the main cabinet. If it is too close, the  
receiver may not function properly.  
• The maximum input impedance of both terminals is 10k ohms. The  
maximum signal level is -10 dB.  
• Beginning with CPC-AII and CPC-B Version 7.0, an internal hold tone  
may be selected in programming. If selected, the internal hold tone will  
always be used even if a sound source is connected to MOH connector  
CN5.  
Installation  
1. If you are using a single source for both BGM and MOH, connect the  
source to CN5 on the Connector Panel. If using separate sources, connect  
the MOH source to CN5 and the BGM source to the BGM connector on  
the SCC card.  
2. Strap the CN5 block (SCC-A) or the CN4 block (SCC-B) according to  
the number of music sources used.

so that your announcement is heard over the key telephones and Digital  
Single Line Telephones that are members of that group. Paging groups often  
include people whose work is related.  
External zone paging allows you to connect up to five speaker groups to the  
DBS. Each speaker group is assigned to one of five paging zones (00-04).  
Zone 00 corresponds to group 00. When you page group 00, your page is  
heard over the All-Page Speaker(s) as well as all other external zones. Zones  
01-04 correspond to groups 01-04. For example, when you page group 02, the  
page is heard on the external speaker(s) assigned to zone 02. Paging groups  
05-07 have no external paging zones.  
If zone paging is not required, general paging relay terminals C (common), B  
(break) and M (make) are also provided. The relay terminals activate any  
time there is a page to an external page group. These are used when paging  
and UNA use the same paging amplifier system. (See notes for more  
information.)  
Guidelines  
• The paging amplifier, zone relays, and speakers are not provided with the  
DBS. They must be purchased separately.  
• The maximum current for each zone paging terminal on the Connector  
Panel (Z0-Z4) is 50 mA; the resistance of the relay used for each zone  
paging terminal must be 2600 to 2800 Ohms.  
• The contact rating for the UNA/General Paging “C” and “M” terminals is  
30V DC, 1 amp (maximum).  
• Connector 4 (CN4) on the Connector Panel is used to connect the paging  
amplifier. The output impedance of CN4 is 600 Ohms; the loss/gain setting  
is 0 dB.  
External Page Zone Installation  
1. Connect the paging amplifier to CN4 on the DBS Connector Panel. (See  
Figure 5-7 on page 5-15.)  
2. Connect the paging speakers to the amplifier and relays.

Section 300-Installation  
Chapter 5. Peripheral Equipment  
• If UNA operates over the paging system, the Audio Output of CN4  
provides the Audio Ringback sound to be heard over the paging system  
when a trunk rings UNA.  
• If UNA operates over the paging system, the UNA ringing will always  
takes precedence over paging. When a page is interrupted in progress, the  
pager must hang up and wait until after UNA ringing ends to reinstate the  
page.  
• If UNA rings over the paging system, set the Ring Patterns for UNA  
Terminals (M, C, & B) to continuous ring burst (FF1 2# 4# 1# 1#). This  
sets the contacts to remain continuously activated during the UNA ring  
broadcast.  
External Ringer (UNA Device)  
Guidelines  
• An external ringer device can be used to alert users when Universal Night  
Answer (UNA) calls come in.  
• The external ringer device is not provided with the DBS. It must be  
purchased separately.  
• UNA calls can also be set to ring over an external paging system. See  
“Paging” on page 5-14 for more information. This alternate connection is  
preferred when both paging and UNA are required.  
• The contact rating for the “C” and “M” terminals is 30V DC, 1 amp  
(maximum).

Installation  
1. Connect the external ringer to the “C” and “M” terminals on the  
Connector Panel. (See Figure 5-9 on page 5-18.)  
Note: When the Ring Patterns for UNA Terminals (M, C, & B)  
programming command (FF1 2# 4# 1# (0 or 1)# is set to 0, connecting the  
ringer to the “C” and “M” terminals provides a “1 second on/3 seconds  
off” ringing pattern and connecting to “C” and “B” terminals provides a  
“1 second off/3 seconds on” ringing pattern.  
2. Connect the external ringer to its DC power source.

Notes:  
• Most often, Unlivery Night Answer notification is provided by an external  
ringer device. Universal Night Answer (UNA) can alternatively be set to  
ring over the paging system. See “Paging” on page 5-14 for more  
information.  
• If UNA operates over a external ringer device, it is not recommend that  
external paging also be used. Since contacts C, B and M activate for both  
UNA calls and external pages, the external ringer device would turn ON  
for all pages.

Door Box Adaptor (Trunk Port)  
Guidelines  
There are two types of door phone adaptors available for the DBS. The first  
type (VB-43701) utilizes a trunk connection to connect to the door box and is  
described below. The second type (VB-43711) utilizes a digital port  
extension to connect to the door box and door opener. See“Door Box Adaptor  
(Extension Port)” on page 5-31 for more information.  
Each Door Box Adaptor (VB-43701) can be used to connect one door sensor  
and up to two Door Boxes (VA-43705) equipped with door openers. Door  
openers and door sensors are not sold by Panasonic; they can be purchased  
separately from an electronics dealer.  
Door Sensors  
• A door sensor is similar to an alarm; different types of sensors detect  
different things, such as a door opening, moisture, heat, etc. When the  
sensor is tripped, a trunk rings on a dedicated key. You can reset the  
“alarm” by answering the key.  
• To set up a sensor, assign a trunk to ring at a phone, and then assign that  
trunk to an FF key.  
• Each sensor uses one trunk port.  
Door Boxes with Door Openers  
• Door Boxes and door openers work together. The Door Box allows  
visitors to announce their presence from outside the office. The door  
opener enables a user to unlock the door using a telephone.  
• To set up the Door Box and opener, assign a trunk to ring at a phone and  
then assign that trunk to an FF key.  
• When a visitor is announced from the Door Box, the user presses the  
ringing FF key to answer the call. Then, to open the door, the user dials 3.  
• The door opener can be set to open the door for 15 seconds, 30 seconds, or  
one minute.  
• Up to two Door Boxes with openers can be connected to a Door Box  
Adaptor.  
• Each Door Box and opener use one trunk port.

Single Line Telephone Adaptor  
Guidelines  
• The Single Line Telephone Adaptor (SLTA, VB-43709) provides an  
alternative way of connecting analog DTMF telephones (2500 sets). One  
SLTA supports up to 4 Single Line Telephones.  
• Each SLT extension requires a digital extension port connection to the  
SLTA.  
Installation  
1. Remove the cover from the SLTA.  
2. Remove the cable punch-out plate (Figure 5-20) to make an opening for  
the cables coming into the SLTA.  
To remove the plate, cut the grooves on either side with diagonal cutters.  
Then bend the plate back and forth with needle-nose pliers to remove it.

Appendix A: CPC-EX 1.0 Updates  
CPC-EX Version 1.0 (and above) offers the following enhancements to the  
DBS phone system:  
Compatibility  
CPC-EX Version 1.0 supports all features of CPC-B Version 7.1 (with the exception of  
TSAPI support). In addition, CPC-EX Version 1.0 adds support for additional features,  
including the 44-Series phones, T1 Networking, and ISDN.  
The CPC-EX card can be installed into an existing DBS cabinet, with no hardware  
modifications.  
CPC-EX software uses existing CPC-B programming addresses, with the same numbering.  
Additional addresses have been added for CPC-EX features.  
Note: CPC-EX requires SCC-B.  
44-Series Phone Support  
CPC-EX provides full support for Panasonic’s 44-Series phones (VB-44xxx). Table 1 below  
lists all 44-Series phone models and their part numbers. Most models are available in two  
colors: gray and black.

Appendix A. EX 1.0 Feature Update  
Section 300-Installation  
Enhanced DBS features that can be executed on the 44-Series phones are described below:  
Directory Mode  
On the small-display phones, you can scroll through SSD names, PSD names, or extension  
names and select a displayed name for dialing.  
Variable Mode  
The small-display phones provide one-touch access to various features displayed during each  
of the following call states: 1) during an intercom call; 2) during CO dial tone; 3) during a  
trunk call; and 4) after dialing a busy extension.  
Handset Mute  
The large-display phone now contains a MUTE key, and a mute feature is available on all 44-  
series phones. Pressing the MUTE key during an off-hook call will block audio from the  
handset transmitter to the outside party. You can still hear them, but they can’t hear you.  
Off-Hook Monitoring  
If you press the ON/OFF key during an off-hook call on any 44-series speakerphone, the  
other party’s voice will be heard through both the handset and the speaker. This allows a third  
party to hear both sides of a conversation. Note: This feature does not activate your phone’s  
microphone - audio will be transmitted only through your handset.  
Analog Adapter  
The large-display phone can be enhanced with an analog port adapter which allows you to  
connect to an analog device such as a FAX or modem to the phone. This allows the same  
phone to be alternately used for analog or digital communications.  
MSG (Message) Key  
A MSG key on the large-display phone will perform Auto-Callback (automatically dialing  
the extension that sent a “Message Waiting” to your phone), or Auto-Answer Message  
(automatically dialing your voice mailbox).  
DSS/72 and EM/24 - Key Arrangement  
The keys on the consoles are arranged differently, affecting the text layout and default  
extension numbers assigned to these keys.

Section 300-Installation  
Appendix A. EX 1.0 Feature Update  
FF-Key Programming  
Because T1 Networking adds the capability of 4-digit extension numbering, you can now  
program up to 8 digits (not 6) into an FF-key.  
Speed Dial Enhancements  
CPC-EX supports up to 500 System Speed Dial (SSD) numbers. CPC-EX also allows SSD  
codes to be chained, or “linked”, to another SSD number, and either PSD or SSD codes to be  
chained to a PSD number.  
Additional Serial Port  
The CPC-EX card contains an on-board serial port (Serial Port 2) which can be used for Bus  
Monitor/Maintenance. This allows remote maintenance to be accomplished without  
disconnecting SMDR cabling.  
T1 Networking Capability  
Up to 4 DBS’s can now be connected together via T1 interface to form a DBS phone  
network. The DBS’s can be located in the same building, in separate buildings in a campus-  
type environment, or at remote locations in separate states. Networked DBS’s use 4-digit  
extensions, with the first digit of the extension number identifying the DBS site.  
Each site requires its own DBS cabinet with a CPC-EX card and a T1 card. Programming  
addresses are included in CPC-EX software for setting up the T1 Network. (see the T1  
Networking Reference Manual for complete instructions.)  
Modification to Toll Restriction Service  
The program address for TRS Operator Access (FF7 1# 18#) has been modified to allow an  
extension to dial “0+NXX” phone numbers, even if “0-only” dialing is denied.  
Maximum Time Priority Route Tables  
CPC-EX allows a maximum of 8 Time Priority Route Tables (not 15) to be used during LCR  
programming. Since few systems use more than 3 Time Priority Route Tables, this change  
will allow the saved memory space to be used for future enhancements.

Appendix A. EX 1.0 Feature Update  
Section 300-Installation  
SMDR Modifications  
SMDR reports contain several additional call types and other parameters due to CPC-EX  
support of T1 Networking and ISDN calls.  
ISDN Support  
CPC-EX supports ISDN-PRI (Integrated Services Digital Network -- Primary Rate  
Interface). The program address for Trunk Circuit Type (FF2 (trunk #)# 21#) has been  
modified to allow for ISDN. Programming addresses have also been added in CPC-EX to  
support ISDN. (See the ISDN Reference Manual for complete instructions.)  
Modification to T1 Signaling Types  
To allow easier programming of E&M trunks, CPC-EX uses “Wink Start” (not “Immediate  
Start”) as the default for T1 Incoming and Outgoing Signal Types.  
Installation Notes  
CPC-EX Installation  
Use normal installation procedures to install the CPC-EX. The following illustration shows  
an installed CPC-EX:

Appendix A. EX 1.0 Feature Update  
Section 300-Installation  
Analog Adapter  
Description  
Operation  
The Analog Adapter (VB-44100) consists of a base adapter and PC board  
which is installed on the underside of the phone. It is used to connect the  
44-Series large-display phone to an analog device such as an SLT  
telephone, cordless phone, FAX machine, or modem. This allows the same  
phone line to be used to alternate between normal phone calls and analog  
communications. (To install, see the instructions supplied with VB-44100).  
The first device to go off-hook will seize the line (off-hook is either lifting  
the handset or pressing the ON/OFF key). If the analog device goes off-  
hook first, the large-display phone will be unable to dial or go off-hook.  
You can choose which device will ring by going off-hook at either the  
digital key telephone or the analog device and dialing *71. The digital key  
telephone display will reflect “Analog port RING” or “Key Tel RING”,  
depending on which device is selected - the default is “Key Tel RING”.  
You can still answer an incoming call from either device, regardless of  
which device is ringing. For example, if the analog device is ringing, you  
can pick up the call on the digital key telephone by going off-hook before  
the analog device does. Similarly, if the digital key telephone is ringing or  
has not answered a voice call, the analog device can pick up the call by  
going off-hook first.  
You can program the *71 ring select command into an FF key. Pressing the  
key toggles between “Analog Port RING” and “Key Tel RING”. When the  
analog port is set to ring, the FF key LED lights red. When the key  
telephone is set to ring, the LED is off.  
Notes  
Phone Restrictions  
• The Analog Adapter will work on the large-display phone only (VB-  
44225).  
• A dial-pulse SLT will not function on the analog port.  
• Stutter Dial Tone (indicating Call-Forwarding mode, Do-Not-Disturb  
mode, etc.) will not function on an SLT connected to the Analog  
Adapter.  
• An analog phone connected to the Analog Adapter cannot program or  
access speed dials.  
Incoming Calls  
• You cannot program both devices to ring simultaneously.  
• The “*71” code will not work if the other device is in use.

Section 300-Installation  
Appendix A. EX 1.0 Feature Update  
• The “*71” code will not work if FF3 (ExtPort)# 51# is set to “0”.  
• If set to “Analog port RING”, the large-display phone will work like an  
SLT/OPX (no page announcements, no voice calls from other  
extensions, etc.).  
• If the phone is in CF/DND (Call-Forward or Do Not Disturb), the phone  
will remain in CF/DND even if the ringing device is changed via the  
*71 code.  
• The incoming ring pattern for the analog device is the same as for the  
digital key telephone (determined by the Extension Ring Pattern in FF3  
(ExtPort)# 39# (0-9)#). If this address is set to “0” (determined by CO),  
the analog device will automatically default to “1 second ON, 3 seconds  
OFF.”  
Ring Patterns Not Applicable to Analog Device. The following ring  
pattern addresses will not affect the analog device:  
Analog Transfer Ring Pattern FF1 2# 1# 31# (0-6)#  
SLT DISA Ring Pattern  
Inbound Ring Pattern  
FF1 2# 1# 34# (0 or 1)#  
FF2 (Trunk)# 17# (0-9)#  
Flash Interaction. Any disconnect signal sent to the analog port must be  
greater than the SLT Flash Control; otherwise the disconnect signal will be  
interpreted as a flash and the call will be placed on hold.  
Programming Addresses That Affect the Analog Device. The following  
addresses will control the analog device, but will not affect the digital key  
telephone:  
AEC Disconnect Duration  
SLT Flash Control  
SLT Onhook Flash Timer  
AEC Disconnect  
FF1 2# 1# 35# (0-15)#  
FF1 2# 1# 11# (0 or 1)#

MSG (Message) Key  
Description  
The MSG key on the VB-44225 Large-Display Phone adds the following  
functionality to the phone:  
• Auto-Callback. If a callback message has been left by another  
extension, you can press the MSG key to place an automatic callback to  
the extension that sent the message. If more than one callback message

has been received, pressing the MSG key will perform auto-callback in  
the order received.  
• Auto-Answer Voice Message. You can press the MSG key to  
automatically access your voice mailbox. The phone will dial your  
voice mailbox and send access codes (if programmed) for retrieving  
messages.  
Operation  
To Program Voice Mailbox Access Codes into the MSG Key:  
Press PROG MSG [16-digit number] HOLD  
The display will reflect “Regist Data”.  
To Confirm a Voice Mailbox Access Code Programmed into the  
Message Key..  
Press CONF MSG.  
The programmed access code will be displayed.  
Notes  
Operation With Message Waiting Indicator. The Message Waiting  
Indicator on the phone’s upper right corner will flash whenever a callback  
message or voice message has been received.  
Operation During Call States. The MSG key will work only when the  
phone is idle, receiving dial tone, or in Directory Mode (via select key).  
Operation If Phone Has Both a Callback Message from another  
Extension and a Voice Message. Messages are accessed in a First In, First  
Out order. If the callback message was received before the voice message,  
then pressing the MSG key will activate Auto-Callback first. Likewise, if  
the voice message was received before the callback message, pressing the  
MSG key will access your Voice Mailbox.  
Interaction with Tone-Calling Mode. If an Auto-Callback is placed to a  
phone that is in tone-calling mode (i.e., not voice-calling), that phone must  
answer or the message canceled before another message can be accessed.  
FF-Key Restriction. These MSG features cannot be assigned to an FF-  
key.  
Reprogramming the MSG key if Extension Number Digits is changed. If  
the DBS is reprogrammed to use a different extension numbering plan (i.e.,  
changed from 2-digit to 3-digit extensions, 3-digit to 4-digit extensions,

etc.), the Voice Mailbox Access Code must be reprogrammed into the  
MSG key.  
DSS/72 Console - Key Arrangement  
Description  
The keys on the DSS/72 Console (VB-44320) are arranged differently  
from the VB-43320 model. The DSS console has 6 columns x 12 rows of  
keys (not 8 columns x 9 rows as in the previous version). This affects the  
following:  
• Name and Message Assignments (FF6 addresses). The alphabetical  
arrangement of the keys is different.  
• FF-Keys. The FF-keys on the DSS/72 console are numbered left-to-  
right, bottom row first.  
• DSS #1 Defaults. The default extension number assignments on DSS #1  
are different.  
The DSS key arrangement is shown in Figures A-7 & A-8.

The keys on the EM/24 unit (VB-44310) are arranged differently from the  
VB-43310 model. The EM/24 unit has 2 columns x 12 rows of keys (not 3  
columns x 8 rows as in the previous version). This affects the following:  
• FF-Keys. The FF-keys on the EM/24 are numbered bottom-to-top, left  
column first.  
The EM/24 key arrangement is shown in Figure A-9.

Additional Serial Port on CPC Card  
Description  
The CPC-EX card contains an on-board serial port (Serial Port 2) which  
can be used for Bus Monitor/ Remote Maintenance. This serial port  
(labeled CN5) is located just above the LEDs on the front of the card (see  
the illustration on Appendix A:-4). This additional serial port allows you to  
dial directly into the system for remote maintenance, without having to  
disconnect the SMDR cabling from the backplane serial port (Serial Port  
1).  
• Serial Port 1 (the backplane port) and Serial Port 2 have separate controls  
for baud rate, stop bit, parity, and data length  
Installation  
Serial Port 2 requires the CPC-EX Serial Port Adapter Cable (VB-43890).  
This cable connects to Serial Port 2 via a 10-pin connector, and to a  
programming terminal via a DB25 connector.

Appendix B. CPC-AII/B 8.0 Feature Update  
Section 300-Installation  
Analog Adapter  
44-Series phones only  
CPC-AII/B Version 8.0, CPC-S/M Version 2.0, or CPC-EX Version 1.0 only  
Description  
The Analog Adapter (VB-44100) consists of a base adapter and PC board  
which is installed on the underside of the phone. It is used to connect the  
44-Series large-display phone to an analog device such as an SLT  
telephone, cordless phone, FAX machine, or modem. This allows the same  
phone line to be used to alternate between normal phone calls and analog  
communications. (To install, see the instructions supplied with VB-44100).  
Operation  
The first device to go off-hook will seize the line (off-hook is either lifting  
the handset or pressing the ON/OFF key). If the analog device goes off-  
hook first, the large-display phone will be unable to dial or go off-hook.  
You can choose which device will ring by going off-hook at either the  
digital key telephone or the analog device and dialing *71. The digital key  
telephone display will reflect “Analog port RING” or “Key Tel RING”,  
depending on which device is selected - the default is “Key Tel RING”.  
You can still answer an incoming call from either device, regardless of  
which device is ringing. For example, if the analog device is ringing, you  
can pick up the call on the digital key telephone by going off-hook before  
the analog device does. Similarly, if the digital key telephone is ringing or  
has not answered a voice call, the analog device can pick up the call by  
going off-hook first.  
You can program the *71 ring select command into an FF key. Pressing the  
key toggles between “Analog Port RING” and “Key Tel RING”. When the  
analog port is set to ring, the FF key LED lights red. When the key  
telephone is set to ring, the LED is off.  
Notes  
Phone Restrictions  
• The Analog Adapter will work on the large-display phone only (VB-  
44225).  
• A dial-pulse SLT will not function on the analog port.  
• Stutter Dial Tone (indicating Call-Forwarding mode, Do-Not-Disturb  
mode, etc.) will not function on an SLT connected to the Analog  
Adapter.  
• An analog phone connected to the Analog Adapter cannot program or  
access speed dials.  
Incoming Calls  
• You cannot program both devices to ring simultaneously.

Section 300-Installation  
Appendix B. CPC-AII/B 8.0 Feature Update  
• The “*71” code will not work if the other device is in use.  
• The “*71” code will not work if FF3 (ExtPort)# 51# is set to “0”.  
• If set to “Analog port RING”, the large-display phone will work like an  
SLT/OPX (no page announcements, no voice calls from other  
extensions, etc.).  
• If the phone is in CF/DND (Call-Forward or Do Not Disturb), the phone  
will remain in CF/DND even if the ringing device is changed via the  
*71 code.  
• The incoming ring pattern for the analog device is the same as for the  
digital key telephone (determined by the Extension Ring Pattern in FF3  
(ExtPort)# 39# (0-9)#). If this address is set to “0” (determined by CO),  
the analog device will automatically default to “1 second ON, 3 seconds  
OFF.”  
Ring Patterns Not Applicable to Analog Device. The following ring  
pattern addresses will not affect the analog device:  
Analog Transfer Ring Pattern FF1 2# 1# 31# (0-6)#  
SLT DISA Ring Pattern  
Inbound Ring Pattern  
FF1 2# 1# 34# (0 or 1)#  
FF2 (Trunk)# 17# (0-9)#  
Flash Interaction. Any disconnect signal sent to the analog port must be  
greater than the SLT Flash Control; otherwise the disconnect signal will be  
interpreted as a flash and the call will be placed on hold.  
MSG (Message) Key  
44-Series phones only  
CPC-AII/B Version 8.0, CPC-S/M Version 2.0, or CPC-EX Version 1.0 only  
Description  
The MSG key on the VB-44225 Large-Display Phone adds the following  
functionality to the phone:  
• Auto-Callback. If a callback message has been left by another  
extension, you can press the MSG key to place an automatic callback to  
the extension that sent the message. If more than one callback message  
has been received, pressing the MSG key will perform auto-callback in  
the order received.  
• Auto-Answer Voice Message. You can press the MSG key to  
automatically access your voice mailbox. The phone will dial your  
voice mailbox and send access codes (if programmed) for retrieving  
new messages.

Operation  
To Program Voice Mailbox Access Codes into the MSG Key:  
Press PROG MSG [16-digit number] HOLD  
The display will reflect “Regist Data”.  
To Confirm a Voice Mailbox Access Code Programmed into the  
Message Key..  
Press CONF MSG.  
The programmed access code will be displayed.  
Notes  
Operation With Message Waiting Indicator. The Message Waiting  
Indicator on the phone’s upper right corner will flash whenever a callback  
message or voice message has been received.  
Operation During Call States. The MSG key will work only when the  
phone is idle, receiving dial tone, or in Directory Mode (via select key).  
Operation If Phone Has Both a Callback Message from another  
Extension and a Voice Message. Messages are accessed in a First In, First  
Out order. If the callback message was received before the voice message,  
then pressing the MSG key will activate Auto-Callback first. Likewise, if  
the voice message was received before the callback message, pressing the  
MSG key will access your Voice Mailbox.  
Interaction with Tone-Calling Mode. If an Auto-Callback is placed to a  
phone that is in tone-calling mode (i.e., not voice-calling), that phone must  
answer or the message canceled before another message can be accessed.  
FF-Key Restriction. These MSG features cannot be assigned to an FF-  
key.  
Reprogramming the MSG key if Extension Number Digits is changed. If  
the DBS is reprogrammed to use a different extension numbering plan (i.e.,  
changed from 2-digit to 3-digit extensions, 3-digit to 4-digit extensions,  
etc.), the Voice Mailbox Access Code must be reprogrammed into the  
MSG key.

EM/24 - Key Arrangement  
44-Series phones only  
CPC-AII/B Version 8.0, CPC-S/M Version 2.0, or CPC-EX Version 1.0 only  
Description  
The keys on the enhanced EM/24 unit (VB-44310) are arranged differently  
from the VB-43310 model. The enhanced EM/24 unit has 2 columns x 12  
rows of keys (not 3 columns x 8 rows as in the previous version). This  
affects the following:  
• FF-Keys. The FF-keys on the EM/24 are numbered bottom-to-top, left  
column first.  
The newer arrangement for the EM/24 keys is shown in Figure 15.

Appendix B. CPC-AII/B 8.0 Feature Update  
Section 300-Installation  
Operation  
The 44-Series EM/24 operates the same as previous models.  
TAPI Support  
CPC-AII/B offers full support for the Panasonic Telephony Applications Processing  
Interface (TAPI). TAPI is a Windows™ application which allows a PC to be connected to a  
telephone extension and used to control incoming and outgoing calls through that extension.  
Typical PC applications that might be used with TAPI include Contact Managers and  
Personal Organizers.  
The Panasonic TAPI product (VB-43720) provides the necessary interface between a DBS  
and a PC-based TAPI application. This product consists of a TAPI Adapter and the  
Panasonic TAPI Service Provider (SP) software which resides on the PC. The TAPI Adapter  
provides the physical connection between a PC, a DBS extension, and the DBS itself. Its  
purpose is to intercept telephone and call control signaling messages from the DBS and  
telephone extension and then forward a copy of those messages to the Service Provider  
software on the PC. After interpreting the messages, the Service Provider software passes  
them on to the TAPI application.  
No special programming of the DBS is required for TAPI. For detailed information, see the  
TAPI Installation Guide, Part Number 575X00201, Section 570.  
Key Telephone Installation Notes  
Desi Strip Cover  
The 44-Series Key Telephones are shipped with a thin green protective film over the Desi  
strip cover. Be sure to remove this film from both sides of the Desi cover before placing the  
phone in service.  
Key Telephone Wall Mounting Instructions  
The following procedures apply to 44-Series Key Telephones only. Please be sure to follow  
these procedures exactly. Removing the desk stand incorrectly can result in damage to the  
telephone and/or desk stand.  
1. Place the telephone face down on a flat surface.  
2. Grasp the top of the desk stand (at the >ABS< label) and pull up the end to 90° vertical  
(refer to Step 2 in Figure D-16). The stand will click as it releases from the plastic securing  
latches.  
3. Lift the desk stand as shown in Step 3 of Figure D-16.
