Attendant Control of Trunk Group

Access

Third Party Make Call capability with the alert_order option (switch-classified calls) and Route Select capability requests cannot be offered to a Trunk Group with active attendant control. In this case, the call is ended and a negative acknowledgement (NAK) is sent to the adjunct.

Calls that provide event reports over domain-controlled associations can access any Trunk Group controlled by the attendant. The attendant is alerted and places the call to its destination.

User-classified calls and forwarded supervisor-assist or direct-agent calls may use trunks controlled by the attendant. Active-notification calls are also allowed to use such trunks. Trunks seized for switch-classified Third Party Make Calls must not have attendant control activated. If they do, such calls are denied (cause CS0/21). For adjunct-routed calls, if the route select capability attempts to route to such a trunk, the step fails (cause CS0/21) and is skipped.

Calls that are initiated using the switch-classified Third Party Make Call Capability cannot be offered to a trunk group with active attendant control. Therefore users and programmers who want to collect charge information within an OCM application should be aware of this limitation.

Attendant Serial Call

The Attendant Serial Call feature allows calls to be returned to the attendant after the party to which the call was extended goes on-hook. The attendant can then drop or extend the call to another station within the ECS.

Attendant Through Dialing

This feature allows the attendant to seize a trunk on behalf of a restricted station and then transfer it to that station; the station then dials an outgoing call.

AUDIX

Calls that cover to AUDIX do not maintain a simulated bridge appearance on the principal’s station. [This is true unless DEFINITY ECS AUDIX is operating without a Data Communications Interface Unit (DCIU) link. In this case, the simulated bridge appearance is maintained.] The principal receives audible alerting followed by an interval of coverage response followed by the call dropping from the principal’s set. When the principal receives alerting, the Alerting Event Report is
