General Description
This feature allows the Attendant to arrange for a recall from a station before releasing a Central Office
call to that station. When the station disconnects from the call, the Central Office party automatically rings
back to the Attendant.
Operating Procedure
1.
Answer the incoming Central Office call.
2.
Extend the call to the desired station.
3.
Press the SC key; the hld lamp corresponding to the loop will light.
4.
The called station and incoming station are connected.
5.
The called station hangs up; the hld lamp and the ATND lamp on the Attendant Console flash at
60 IPM. If the Attendant position is available, an audible indication will be provided.
6.
Press the associated loop key to return to the incoming calling party.
Service Conditions
1.
This service feature is effective only for incoming calls from external trunks.
2.
If the Attendant enters a loop that is already set up for SC, the service is automatically cancelled.
3.
SC is not provided for station-to-station calling.
4.
SC can be provided on a per-tenant basis.
5.
SC is allowed when a station is involved in an ATTENDANT CONTROLLED CONFERENCE.
6.
STATION MESSAGE DETAIL RECORDING - (SMDR) [S-10]: The duration of the total call is
recorded on the last station call.
7.
When the ATTENDANT LOCKOUT [A-5] feature is provided, the Attendant cannot reenter the
connection without being recalled.
8.
This feature is not applicable for tandem connections.
9.
In the Loop Release system, once this service is set, the attendant position enters the idle state,
and the established call is released from the loop, enabling all hooking services at the extension
side. ASYD, System Data 1, Index 186, bit 4 = 1.
10. The Attendant sets this service by pressing the SC key when the extension user answers.
11. It is not possible to release this service once it is set.
12. If the operator presses the SC key before the called extension answers (Non-Delay mode
service setting), the external calling party receives a Ringback Tone, and the Attendant position
enters the idle state.
13. In the Non-Delay mode service, setting the extension loop release does not occur until the called
extension answers, even though the Loop Release system is specified by the System Data
setting (System Data 2 INDEX 2 b5 = 1). The operator is allowed to reenter the connection before
the extension answers, though the SERIAL CALL service remains set.
14. CALL PICKUP GROUP [C-7] feature can be used for answering a call handled by the operator
in the Non-Delay service setting mode.
15. CALL FORWARDING-DON'T ANSWER [C-3] feature cannot be used if SC is set.
