Priority Call P-9
P-9 Priority Call
General Description
This feature allows the ATTENDANT CONSOLE [A-3] to answer various types of calls in the order of their
priority. A special type of call can be handled prior to a regular call, at the Attendant's discretion.
Operating Procedure
1. Lift the handset and receive dial tone.
2. Dial the PRIORITY CALL number, then wait for the Attendant to answer.
Note: PRIORITY CALL will terminate on a designated key on the ATTENDANT CONSOLE [A-3].
Service Conditions
1. The PRIORITY CALL must be answered via a designated key in order to gain a priority capability. The
keys must be assigned by the MAINTENANCE ADMINISTRATION TERMINAL (MAT) [M-18].
2. A PRIORITY CALL will not be picked up first, by pressing the ANSWER key, if other calls are waiting.
3. A PRIORITY CALL cannot be initiated while in CONSULTATION HOLD - ALL CALLS [C-17] or
CALL HOLD [C-6].
4. In the night mode, a PRIORITY CALL will terminate at the predetermined station.
5. The calling station obtains this feature via CLASS OF SERVICE - INDIVIDUAL [C-15].
6. A station, instead of the ATTENDANT CONSOLE [A-3], can be the destination of a PRIORITY CALL
in the day mode.
7. If the PRIORITY CALL encounters the destination station busy, the call will wait for the station to become
idle. Ringback tone will be heard while the caller is waiting.
8. Three levels of PRIORITY CALLs can be assigned.
9. When the destination is a station, the originating stations should be assigned as a member of a PRIORITY
CALL group. The maximum number of PRIORITY CALL groups is 7 per TENANT [T-12]. The
terminating station must be assigned to each PRIORITY CALL group.
10. The terminating station of each group can be a member of a HUNTING GROUP [S-7, 8, 9].
11. The terminating station can set CALL FORWARDING - ALL CALLS [C-5] and CALL FORWARDING
- BUSY LINE [C-2].
12. The terminating station for ATTENDANT NIGHT TRANSFER [A-19] and/or OFF-HOOK ALARM [O-
6] can be assigned as the terminating station of a PRIORITY CALL.
13. If the destination D
term
is busy (and not the pilot number of a UCD group), when a Priority Call is placed,
ringback tone is returned to the calling party rather than busy tone, and the calling party is placed in queue.
14. When a UCD [U-1] station is assigned as the destination of PRIORITY CALL, queuing function of UCD
is not available when all the stations within the UCD group are busy.
15. The Fusion Point Code (FPC) of the node which accommodates the called Attendant Console must be
assigned after system data assignment.
Interactions
1. If the destination D
term
is busy when a Priority Call is placed, ringback tone is returned to the calling party
rather than a busy tone, and the calling party is placed in queue.
2. A Warning Tone is not provided at the called D
term
while a Priority Call is in progress.
