Uniform Call Distribution (UCD) - PRI U-6
Service Conditions (cont’d)
8. If the Attendant transfers a call to a busy UCD group, the call waits in queue until a station in the group
becomes idle. However, a station cannot transfer a call to a busy UCD group.
9. Incoming calls to individual stations in the group are not distributed around the group; only calls to the
UCD group number use the circular distribution.
10. Each UCD group has a controlling station. Only the controlling station or the Attendant can activate or
deactivate CALL FORWARDING - ALL CALLS [C-5] when the UCD group number is not a phantom
number. UCD does not work at the CALL FORWARDING - ALL CALLS [C-5] destination, even if the
destination station is a controlling station.
11. If CALL FORWARDING - ALL CALLS [C-5] is set on a controlling station and the destination station
is idle, a call to the UCD group is transferred. If the designated station is busy, the user hears busy tone.
12. If CALL FORWARDING - ALL CALLS [C-5] is set on a non-controlling station, that station is skipped
in any UCD hunt.
13. The Attendant can use BUSY VERIFICATION [B-3] to check the busy/idle condition of the UCD
stations. This feature cannot determine if the user used the Make Busy feature.
14. CALL WAITING - ORIGINATING [C-31] can be activated by an individual UCD station toward anothe r
station within the system. Also, another user can activate this feature toward an individual UCD group
station.
15. CALL WAITING - TERMINATING [C-12], when assigned to an individual UCD group station, allows
the calling station to wait on the called station’s line when it is busy. The group user can be connected to
the waiting call by hanging up; the station rings and the call is connected when the caller goes off-hook.
These calls have priority over UCD calls in the queue.
16. CALL BACK [C-1] can be activated by an individual UCD group station toward another station. Also,
another station can activate this feature toward an individual UCD station. CALL BACK [C-1] can be
activated toward a UCD group number when all stations and UCD queue are busy. CALL BACK [C-1] is
set to the controlling station.
17. A UCD group number can be used as the destination station of DIRECT-IN TERMINATION [D-7] or
NIGHT CONNECTION - FIXED [N-1], NIGHT CONNECTION - FLEXIBLE [N-2].
18. When a phantom number is assigned to the controlling station of a UCD group, the phantom number is
the UCD group number.
19. UCD queueing has precedence over CALL FORWARDING - INTERCEPT/ANNOUNCEMENT -
ATTENDANT [A-1]. During queuing block, the CALL FORWARDING - INTERCEPT/
ANNOUNCEMENT - ATTENDANT [A-1] is valid. The Attendant hears reorder tone when the CALL
FORWARDING - INTERCEPT/ANNOUNCEMENT - ATTENDANT [A-1] is restricted.
