A device that places a telephone call.
A feature that tracks calls of unusual duration to facilitate troubleshooting. A high
number of very short calls or a low number of very long calls may signify a faulty
trunk.
Representation of the calling number, for display or for further use to access
information about the caller. Available with Signaling System 7.
A service that restores disrupted connections between access endpoints
(nonsignaling trunks) and data endpoints (devices that connect the switch to data
terminal and/or communications equipment). Restoration is done within seconds of a
service disruption so that critical data applications can remain operational.
A feature that allows the system to automatically choose the least-cost way to send
a toll call.
A trunk that does not require addressing information because the destination is
predetermined. A request for service on the trunk, called a seizure, is sufficient to
route the call. The normal destination of an automatic trunk is the communications-
system attendant group. Also called automatic incoming trunk and automatic tie
trunk.
Auxiliary
Equipment used for optional system features, such as Loudspeaker Paging and
Music-on-Hold.
A trunk used to connect auxiliary equipment, such as radio-paging equipment, to a
communications system.
A work mode in which agents are unavailable to receive ACD calls. Agents enter
Aux-Work mode when involved in non-ACD activities such as taking a break, going
to lunch, or placing an outgoing call.
