channel Glossary

channel

A communication path linking two points for transmitting voice and data. Also:

1.A circuit-switched call.

2.In wideband, all of the time slots (contiguous or noncontiguous) necessary to support a call. Example: an H0-channel uses six 64-kbps time slots.

3.A DS0 on a T1 or E1 facility not specifically associated with a logical circuit-switched call; analogous to a single trunk.

circuit

1.An arrangement of electrical elements through which electric current flows.

2.A channel or transmission path between two or more points.

circuit pack

A card on which electrical circuits are printed, and IC chips and electrical components are installed. A circuit pack is installed in a switch carrier.

Class of Restriction (COR)

Afeature that allows up to 64 classes of call-origination and call-termination restrictions for voice terminals, voice-terminal groups, data modules, and trunk groups.

Class of Service (COS)

A feature that uses a number to specify if voice-terminal users can activate the

Automatic Callback, Call Forwarding All Calls, Data Privacy, or Priority

Calling features.

circuit-switched network

A network that sets up and maintains a connection for the exclusive use of two or more communicating parties for the duration of their call. The familiar, voice telephone network is circuit-switched. See packet switching.

clear-channel facility

A digital circuit that requires no in-channel framing or control bits. The whole bandwidth is thus available for data transmission.

client

An application that runs on one processor while drawing on data or other resources that are on a server located elsewhere. MMCX client: a workstation capable of making MMCX calls. Such a workstation is a client of one or more MMCX servers. See dial-plan table.

CMDR

Centralized Message Detail Recording. (Same as CDR and SMDR).

CMS

Call Management System.
