Supervisory Call - CCIS S-73
S-73 Supervisory Call - CCIS
General Description
This feature allows an Attendant, in a CCIS network, to set Supervisory Call status before releasing a Central Office
call to a station. When the call is extended to a station, the loop will remain up until the called station answers. This
overrides ATTENDANT LOOP RELEASE [A-6] on a per call basis.
Operating Procedure
To activate a SUPERVISORY CALL - CCIS from the ATTENDANT CONSOLE [A-3]
1. The Attendant answers an incoming Central Office call.
2. The Attendant extends the call to the desired station.
3. The Attendant presses the SP SET key; the HOLD lamp corresponding to the loop will light.
4. The called station and incoming call are connected.
5. The called station switch hook flashes; the HOLD lamp on the ATTENDANT CONSOLE [A-3] flashes
at 60 IPM. If an Attendant position is available, an audible indication will be provided.
6. The Attendant presses the associated loop key to return to the called station; the calling station is placed
on hold (MUSIC ON HOLD [M-7]).
Service Conditions
1. If the Attendant enters a loop that is already set up for a SUPERVISORY CALL - CCIS, the service is
automatically cancelled and a three-party connection is established.
2. SUPERVISORY CALL - CCIS is not provided for station-to-station intra-node calling.
3. SUPERVISORY CALL - CCIS can be provided on a TENANT [T-12] basis.
4. A station at which SUPERVISORY CALL - CCIS has been activated will automatically recall to the
Attendant if that station switch hook flashes.
5. If the incoming Central Office call or the station releases during the SUPERVISORY CALL - CCIS, the
loop becomes idle at the ATTENDANT CONSOLE [A-3].
6. When the Attendant answers a recalled SUPERVISORY CALL, the service is complete. If the call is to
be extended to another station, SUPERVISORY CALL - CCIS can be re-established.
7. SUPERVISORY CALL - CCIS is provided for inter-node station-to- station calling in a CCIS network.
8. The SUPERVISORY CALL status will also provide simultaneous SERIAL CALL [S-15] [S-52] service.
9. The following services are restricted while this service is activated:
AUTOMATIC CAMP-ON WITH TONE INDICATION - CCIS [A-45]
BUSY VERIFICATION - CCIS
[B-9]
CALL HOLD [C-6]
EXECUTIVE RIGHT-OF-WAY [E-8]
Interactions
SUPERVISORY CALL - CCIS is normally used in a loop-release ATTENDANT CONSOLE [A-3] setup, so that
calls that are normally released from the Attendant loop can be monitored on a per-call basis.
