Automatic Circuit Assurance (ACA)
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.
Automatic Number Identification (ANI)
Representation of the calling number, for display or for further use to access information about the
caller. Available with Signaling System 7.
automatic restoration
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.
Automatic Route Selection (ARS)
A feature that allows the system to automatically choose the least-cost way to send a toll call.
automatic trunk
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.
