Uniform Call Distribution (Ucd) - NEC NEAX 2400 ICS Features Manual

U-1
General Description
This feature distributes incoming calls to a UCD group of up to 20 stations. Calls are distributed to idle
stations in a circular pattern, in the order in which they arrive.
Operating Procedure
(Series 6200 software enhancement) To transfer a call to a busy UCD group:
1. All the stations in a UCD group are busy.
2. A station user not in the group answers an incoming call (trunk or station).
3. The station user dial the UCD primary number after pressing the switchhook or the XFR key.
a.) The station 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 is hearing Ring Back Tone. (during ringing)
6. The idle station answers the call.
a.) Now the calling party is connected to the UCD station.
Service Conditions
(Series 6200 software enhancement) The maximum number of UCD groups is as follows:
1.
IMG, IMGx:
IMGxh, IMGdxh, MMG, UMG, UMGx:
2. A UCD group may have from 2 to 20 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 station user can block UCD calls by dialing a Busy Out (BYO) code (1 to 3 digits), or if it is a
term
D , by pressing the DND or BYO key. The station user can still originate calls from and receive
calls to its own station number. The station 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. (Series 6200 software enhancement) If the Attendant or the station 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.
