CPC-EX Version 1.0 offers the following new 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 new features, including the 44-Series
phones, Tl 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 new CPC-EX features.
44-Series
CPC-BX
Phone Support
provides full support for Panasonic’s
44Series
phones
(VB4xxx).
Table 1 below lists all
44-Series phone models and their part numbers. Most models are available in two colors: gray and
On the new small-display phones, you can scroll through SSD names, PSD names, or extension
names and select a displayed name for dialing.
Variable
.Mode
The new 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 new large-display phone now contains a MUTE key, and a new mute feature is available on all
&series

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.
-
Separate Volume Control for Internal vs. CO calls
CPC-EX allows you to establish separate speaker volumes for internal and external calls.
Analog Adapter
The new 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 new 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 new consoles are arranged differently, affecting the text layout and default extension
numbers assigned to these keys.
Because Tl Networking adds the capability of 4-digit extension numbering, you can now program
up to 8 digits (not 6) into an
IF-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.
Tl
Networking Capability
Up to 4 DBS’s can now be connected together via Tl 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 Tl card. ‘New programming
addresses are included in CPC-EX software for setting up the Tl Network. (see the
Reference Manual for complete instructions)

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.
SMDR Modifications
SMDR reports contain several new call types and other parameters due to CPC-EX support of
Networking and ISDN calls.
Tine 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.

single or double DBS cabinet configuration. The connection between these systems is accomplished
via Tl talk paths, with the quantity determined during installation.
Network Extension to Extension Calling
Networked DBS’s use a 4-digit extension numbering plan. The first digit determines the node being
called. For example:
When an extension in one node is called via the intercom from an extension in a different node, the
called extension rings - Intercom Voice Calling and OHVA do not work when calling from one node
to another.
The DBS determines how to route the calls based on the network trunk group priorities established
during programming. To allow optimum flexibility in a 4-node network, up to 3 different trunk
group priorities can be established.

Any call can forward to an extension on any node by assigning the targeted extension number in a
Personal Speed Dial bin. To establish the call forward setting, the user follows normal call
forwarding settings and uses the (AUTO)XXX personal speed dial number entry.
Every node can allow or deny network paging for each class of service.
Network Route Selection
A’new option is available for Forced Least Cost Routing to include network route selection. This
option provides 50 6-digit entries which determine how dialed numbers are routed through the
network for optimal cost performance.
For example, if Node 1 of a networked system is in the 20 1 area code and Node 2 is in the 2 12 area
code, all calls from Node 1 to the 212 area code or surrounding area codes can be routed through the
second node to the public network.
Remote CO Access
End users in one node can also place calls manually through a distant node by dialing the node
number followed by a trunk group (9).
SMDR
New options are available in CPC-EX to support call accounting in networked systems.These
Network Support
options are:
Specifying the call record to be printed. A new field has been added:
FF12# 2#/
In the actual SMDR record output, network traffic will be indicated by the following new record
types:
W = CO Outgoing to Network
w = CO Incoming from Network
= Network Transfer
t
The following new data output is found in the extension number field:
A central network operator can be assigned for Dial 0 access from any node. Each node can
independantly designate a network attendant. For example, Nodes
1,2 &
3 can send Dial 0 calls to
the attendant on Node 1, while Node 4 sends Dial 0 calls to its local attendant.

Extension Number Digits
Description
Programming
The CPC-EX card allows a 4-digit extension numbering plan to be used on
networked DBS systems. The first digit of the extension determines on which
DBS the extension is located - for example, extension 1321 will be on DBS 1,
while extension 2547 will be on DBS 2. Each DBS routes calls based on the
leading digit of the dialed extension.
A DBS operating in a network environment must use the 4-digit extension
numbering plan. Stand-alone (non-networked) DBS systems, however, must
continue to use 2 or 3 digit extensions.

New Programming Addresses
New programming addresses have been added to support Tl Networking. These new addresses are
applicable only in a networked environment and can be ignored in a stand-alone (non-networked
DBS). Refer to the Tl Networking Reference Guide for detailed information.
The Operator Access address applies only to DBS systems using the new

CPC-EX allows a maximum of 8 Time Priority Route Tables to be used during
LCR programming.
(CPC-AIL/B
allows a maximum of 16 Time Priority Route
Tables. This number is reduced with CPC-EX since very few systems require
more than 3 of these tables and the saved memory space will allow for a planned
future enhancement.)
The DBS uses Time Priority Route Tables to route calls to the least expensive
carrier based on the time of day the call is placed. The following program
addresses use Time Priority Route Tables:
Station Message Detail Recording (SMDR) provides detailed call records of
outgoing calls. SMDR records can be output to a printer or an external call
accounting system. Additional call record types have been added to the SMDR
feature to support network calls and ISDN calls.
Figure 17 shows the SMDR format for CPC-EX. New values added for CPC-EX
are shaded.
A printer or external call accounting system is required to receive SMDR data.
Considerations
l
Unlike other CPC circuit cards, the CPC-EX supports two serial ports. Serial Port
1 is labeled CN4 and is located on the backplane. Serial Port 2 is labeled
is located on the front of the CPC-EX card. Serial Port 2 requires a special
interface cable.
