12. DCP Mode 3 Installation and Administration

_ ______________________________________________________________________________________

Digital Communications Protocol (DCP) Mode 3 uses 64 Kbps, end-to-end, packet-mode operation for data

transmission. It may be used in the following setups:

• Local Networking: If you are installing a DCP Mode 3 network for two or more colocated (local)

AUDIX systems (the AUDIX systems are connected to the same switch), refer to Chapter 9, DCP

Cabling and Administration. There you install and translate each AUDIX system with the extension

numbers required for each network channel. There are no requirements except extension numbers for a

local AUDIX network.

• Remote Networking: If you are installing a DCP Mode 3 network that requires interlocation facilities,

these facilities are typically T1 Carrier employing common (clear) channel signaling or an Integrated

Systems Digital Network (ISDN) pipe.

This chapter covers administration and testing for DCP Mode 3 AUDIX networking setups.

SWITCH COMPONENT INSTALLATION

See the appropriate switch and/or feature documentation for installing circuit packs and wiring trunks on

the switch.

SWITCH ADMINISTRATION

See the appropriate switch and/or feature documentation for ISDN administration. For DS1 administration

of either local or remote AUDIX networking setups, see the following sections.

System 75, Generic 1, and Generic 3 Administration

The DS1 circuit pack uses the Common Channel Signaling mode to provide 23 trunks for data transmission

and one channel for signaling. The DS1 trunk group must be assigned for AV/D.

At this time, use standard AV/D DS1 administration. Any speciﬁc assignments that become necessary for

AUDIX networking will be covered in future issues of this document.
