Uniform Call Distribution (UCD) U-1
Service Conditions (cont’d)
b.) When stations belonging to different nodes are assigned to a UCD group, the station hunt is not
activated in assigned order if the stations are not assigned in continuous order within a node.
First, the call is shifted to the stations within the node of the UCD controlling station, even though
it is not in consecutive order (in the node, station hunt is activated in assigned order). After all the
stations in the node are hunted, the station hunt is shifted to the next assigned station and the
stations in the node are hunted in assigned order. See the figure below.
40. Phantom Telephone Number (PHTELN) can also be assigned to each telephone number (a maximum of
16 PHTELNs per TELN, TELNs + PHTELNs in total = 60,000 or less). The assigned PHTELN may or
may not be the UCD group number by the APHNN command setting (see Interactions).
41. When activating this feature via the FCCS network, BUSY OUT is available for the station assigned by
the telephone number.
42. When a call terminates to the UCD station through FCCS link, MCI data can be output. MCI text format
is designated via the ASYDL command.
43. When activating this feature via the FCCS network, when PEG COUNT [P-7] service is provided, UCD
Route Peg Count/UCD Group Peg Count/UCD Station Peg Count is available.
44. When activating this feature via the FCCS network, in regard to CALL WAITING LAMP - UCD [C-76]
service, if a UCD incoming call is terminated when the queue slot is full, the lamps of the stations in the
same node that accommodates the controlling station, start to flash.
45. When activating this feature via the FCCS network, a UCD station assigned by the telephone number
cannot be a destination station for DIRECT-IN TERMINATION (DIT) [D-7] or NIGHT CONNECTION
FIXED/FLEXIBLE [N-1/2].
46. A UCD group may accommodate members from four different Fusion Point Codes.
47. When all FCCS links are busy:
a.) UCD member stations belonging to the node where the UCD controlling station is not
accommodated are not hunted.
b.) when all UCD stations in a hunt group are busy, incoming calls routed to the group are not
queued. The calling party hears busy tone.
Example
:
 Station No. 1 is the UCD controlling station. When the call encounters busy, the call is hunted in order of No. 3, No. 
4 (hunted in the node of the controlling station) to No. 2, No. 6, No. 8 (hunted in the node C that accommodates the 
next station in assigned order) to No. 5, No. 7.

Service Conditions (cont’d)
c.) When the CCIS line is used as the alternative routing, SERVICE DISPLAY is not activated and
the hunting function is completed at the terminated station.
48. When using a Phantom Telephone Number (PHTELN) for a UCD controlling station via FCCS, consider
the following:
a.) Whether to use the PHTELN to start the UCD hunt or not can be selected by the command
APHNN. When using the PHTELN, assign “1” in the “PH” parameter. If not, assign “0”.
b.) When “PH = 1”: UCD hunt starts by dialing either the Telephone Number of the controlling
station or its Phantom Telephone Number. Both numbers can be the UCD group number.
c.) When “PH = 0”: UCD hunt starts by dialing the Telephone Number of the controlling station
only. The feature is not provided when the PHTELN is dialed.
Interactions
1. UCD PEG COUNT information is available using Traffic commands. Refer to PEG COUNT [P-7] for
more information.
2. CALL FORWARDING-ALL CALLS [C-5]: Only the controlling station or the Attendant Console can
activate this feature. When activated, calls to the UCD group will be diverted. If the destination station is
busy, busy tone is returned to the calling party. If the UCD group number is a Phantom Number, CALL
FORWARDING-ALL CALLS [C-5] cannot be activated.
3. CALL FORWARDING ALL CALLS/BUSY LINE [C-2, 5]: When a member station in a UCD group
activates CALL FORWARDING-ALL CALLS [C-5] or CALL FORWARDING-BUSY LINE [C-2],
only calls directed to that station are forwarded. UCD group calls are not affected. UCD calls will bypass
the call forwarded station.
4. CALL FORWARDING-DON’T ANSWER [C-3]: All calls terminating at a UCD station will forward if
the call is not answered before the Call Forwarding timer expires. 
5. There is no peg count for calls directed to a UCD group which terminate to a station outside the UCD
group due to CALL FORWARDING [C-2, 3, 5].
6. ATTENDANT CAMP-ON WITH TONE INDICATION [A-1]: UCD calls extended by the Attendant to
the controlling station will not camp-on unless all of the non-controlling stations are either busy or in the
Busy Out state, and the controlling station is engaged in a two-way conversation. Then the call will camp-
on to the controlling station and will terminate at the first available station. 
7. In the event of a non-UCD call extended to a member station of a UCD Group, ATTENDANT CAMP-
ON WITH TONE INDICATION [A-1] will operate normally. 
8. If the UCD controlling station answers an ATTENDANT CAMP-ON WITH TONE INDICATION [A-1]
call using CONSULTATION HOLD-ALL CALLS [C17], there is no peg count. 
9. BUSY VERIFICATION [B-3]: This feature can be used by the Attendant to check the busy/idle condition
of an individual station assigned to a UCD group. When this feature is used against an individual station
that is idle but has set Busy Out, the Attendant will receive reorder tone. 
10. BUSY VERIFICATION [B-3] will activate the normal hunting sequence, and the next station in the UCD
group scheduled to receive the call will be rung. BUSY VERIFICATION [B-3] will operate only when all
the stations in the group are busy, and only if the station is engaged in an actual call. 
11. A D
term user can set or cancel Busy Out at any time and from any condition (idle, busy, three-way
conference, PRIVACY RELEASE [P-18]), simply by pressing the BUSY OUT key. 
12. Single-line users can set Busy Out by going off-hook and dialing the BUSY OUT access code, or from the
switch hook flash, by dialing the BUSY OUT access code when engaged in a normal two-way
conversation.

13. The DND key functions in the same manner as the BUSY OUT key for UCD calls. However, while the
BUSY OUT key allows non-controlling UCD stations to receive calls dialed directly, use of the DND key
restricts all incoming calls.
14. If OVERFLOW-UCD [O-13] is in service, overflow will take place if all the stations in the first group are
busy or in the Busy Out state.
15. If the OVERFLOW-UCD [O-13] group is also busy, queuing to the first group takes place. 
16. Once BUSY OUT cancel code is activated, any UCD call in queue will automatically be directed to and
ring the cancelling UCD station.
17. BUSY OUT set/cancel cannot be activated by a D
term user from the idle (on-hook) condition if the My-
line is in use by another Dterm user. The Dterm user must first go off-hook or press the SPEAKER key (even
though no line will actually be seized), before pressing the BUSY OUT set/cancel key. 
18. If the system is reset, traffic measurement requests are no longer in service.
19. When using a Phantom Number for a UCD controlling station, consider the following:
a.) Whether to use the Phantom Number to start the UCD hunt or not can be selected by the
command APHN. When using the Phantom Number, assign “1” in the “PH” parameter. If not,
assign “0”.
b.) When “PH = 1”: UCD hunt starts by dialing either the station number of the controlling station or
its Phantom No. Both numbers can be the UCD group number.
c.) When “PH = 0”: UCD hunt starts by dialing the station number of the controlling station only.
The feature is not provided when the Phantom Number is dialed.
