Signaling Code
* 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.

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.”

Ground Start and DID Trunks
Guidelines
• The following procedure covers ground-start (VB-43531) and DID (VB43541) installation using the main trunk connector. For instructions on
using the expansion trunk connector, see “Trunk and Line Expansion” on
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 loopstart 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.

Chapter 4. Trunks and Lines

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.

T1 Interface

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.

Trunk Assignments for Double-Cabinet Systems
• When T1 is used in a double-cabinet system, the number of T1 channels
that can be assigned in each cabinet depends on the master/slave
designation.
The following table shows the maximum number of T1 channels that can
be assigned in two-cabinet systems.

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.

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
• 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).

Installation
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.

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.

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.

Section 300-Installation

Paging
The DBS allows extensions to be grouped into paging groups numbered 0007. When you issue a page (by dialing #00-#07), you specify a paging group,
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.

information on UNA external ringer device installation.)

5-16

DBS Manual - Revised April 2000

DBS-2.3/9.2-300

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.

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.

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 44series 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 campustype 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.

Page A-3

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:

Analog Adapter
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 offhook 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 (VB44225).
• 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.

Page A-12

DBS Manual - Revised April 2000

DBS-2.3/9.2-300

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
FF1 2# 1# 34# (0 or 1)#
Inbound Ring Pattern
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
FF1 2# 1# 35# (0-15)#
SLT Flash Control
FF1 2# 1# 11# (0 or 1)#
SLT Onhook Flash Timer
FF1 3# 14# (0-6)#
AEC Disconnect
FF3 (ExtPort)# 46# (0
or 1)#

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 FFkey.
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,

Page A-14

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-toright, 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.

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.

• 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
FF1 2# 1# 34# (0 or 1)#
Inbound Ring Pattern
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.

Section 300-Installation

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.
