U-1 Uniform Call Distribution (UCD)
U-1 Uniform Call Distribution (UCD)
General Description
This feature distributes incoming calls to a UCD group of up to 100 stations. Calls are distributed to idle stations in
a circular pattern, in the order in which they arrive.
Operating Procedure
To transfer a call to a busy UCD group
1. All the stations in a UCD group are busy.
2. A user not in the group answers an incoming call (trunk or station).
3. The user dial the UCD primary number after pressing the switch hook or the TRANSFER key:
a.) The user hears busy tone.
b.) The calling party is held.
4. The station goes on-hook.
a.) The calling party hears Ring Back Tone (during queuing).
5. The UCD group becomes idle:
a.) The call terminates to an idle station in the UCD group.
b.) The calling party hears Ring Back Tone. (during ringing)
6. The idle station answers the call:
a.) The calling party is connected to the UCD station.
Service Conditions
1. The maximum number of UCD groups is 63.
2. A UCD group may have 100 stations.
3. UCD groups are assigned through the MAINTENANCE ADMINISTRATION TERMINAL (MAT) [M-
18].
4. Stations are arranged in a circular-type hunt group. A call to the group starts at the first idle station, after
the last station that received a call.
5. If all of the group’s stations are busy, the call waits in a queue. The caller hears ringback tone. The first
call in the queue will be answered.
6. CALL WAITING LAMP-UCD [C-76] will light (if programmed) after calls are in queue and will flash
when the threshold value for that UCD group is reached.
7. A user can block UCD calls by dialing a Busy Out (BYO) code (1 to 3 digits), or if it is a D
term
, by pressing
the DND or BYO key. The user can still originate calls from and receive calls to its own telephone number.
The user can dial the BYO code from a normal dial tone connection or from a CONSULTATION HOLD-
ALL CALLS [C-17] condition.
8. Each UCD group is assigned a UCD group number, allowing DIRECT INWARD DIALING (DID) [D-8]
calls to be routed to selected groups.
9. If the Attendant or the user transfers a call to a busy UCD group, the call will wait in queue until a station
in the group becomes idle.
10. Incoming calls to individual stations in the group are not distributed by UCD hunting. Only calls to the
UCD group number follow the circular distribution.
