MANUAL VERSION 11.0 – May 2008
Relay: (6-pin, 6-conductor modular jack) Currently used for power failure transfer
equipment only. A power failure transfer jack can be used for connecting one or more
single-line sets to predetermined CO [local exchange] trunks in the event of processor
card failure or a power failure. The output is one normally-open (deactivated) double-
pole, double-throw (DPDT) relay (actually wired as SPDT) that is held closed (acti-
vated) during system operation. Additional equipment needed includes a customer-pro-
vided PFT relay card and card mounting case. The relay contact ratings are listed below.
(See page 2-103 for additional requirements.)
Music-On-Hold Port: Connects an external music source (such as a radio, tape player,
etc.) that can be heard by callers when they are placed on hold or camped on. It may
also be used for phone background music. This is an 1/8-inch (3-mm), two-conductor
(mono), mini-phone jack. For installation instructions, see
ming, music can be enabled or disabled, and each trunk group (as well as transfer
audio) can be assigned music, silence, or tick tones. See
MING. This port supports A-law or mu-law companding, which is configured in DB
Programming (System\Flags\Companding Type).
External paging jack: (RCA-type phono jack with an output impedance of 600 ohms)
Connects external paging speaker equipment to allow paging to large areas, such as
warehouses or loading docks. For installation instructions, see
Built-in Network Clock Card (NCC): Provides the smooth, error-free clock transi-
tions required for T1 applications. If any T1 Cards are installed in the equipment chas-
sis, the network clock circuitry provides the clock function for the entire system.
Do not use a Network Clock Card (NCC) with the CPC. Using an NCC with this card
causes erratic problems which may disable the system. If upgrading an existing
CPU64 or CPU128 to a CPC, you must remove the NCC before installing the CPC. If
the CPC detects an NCC, the system will continually reset.
Software Security and Feature Program: Supports a software license that enables
functionality on the card. This feature serves two purposes: 1) the PAL is no longer
required; and 2) feature and/or device upgrades are possible without replacing the card.
For details about the software security and feature program, see
Modem: Provides a built-in modem that is capable of transferring data at speeds up to
33600 bps. This modem is always equipped and is basically a system serial port that
you must "call." Because the connection is established via a call, each CPC modem in a
chassis is assigned an extension (1500 by default). For details about the modem, see
page 6-180.
Rechargeable Battery: Replaces the lithium battery that is available on CPU cards and
is rechargeable. If the power to the CPC is lost, this battery will store the system data-
base for up to a month (30 days). After power is restored, the battery recharges itself.
This battery can be recharged more than 400 times before it needs to be replaced.
