Uniform Call Distribution (UCD) U-1
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.
11. 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.

U-1 Uniform Call Distribution (UCD)
Service Conditions (cont’d)
12. 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 will hear busy tone. 
13. If CALL FORWARDING-ALL CALLS [C-5] is set on a non-controlling station, that station is skipped
in any UCD hunt. 
14. The Attendant can use BUSY VERIFICATION [B-3] to check the busy/idle condition of the UCD
stations. If the BYO code or key has been used, the Attendant will receive a reorder tone.
15. CALL WAITING-ORIGINATING [C-31] can be activated by an individual UCD user towards another
station within the system. Also, another user can activate this feature towards an individual UCD group
station. CALL WAITING-ORIGINATING [C-31] can be activated toward a UCD group number when
all the stations and the queue are busy. Waiting is set to the controlling station.
16. CALL WAITING-TERMINATING [C-12], when assigned to an individual UCD group station, allows
the calling user 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.
17. CALL BACK [C-1] can be activated by an individual UCD group user towards another station. Also,
another user can activate this feature towards an individual UCD station. CALL BACK [C-1] can be
activated toward a UCD group number when all the stations and UCD queue are busy. CALL BACK [C-
1] is set to the controlling station.
18. A UCD group number can be used as the destination station of DIRECT-IN TERMINATION [D-7] or of
NIGHT CONNECTION-FIXED/FLEXIBLE [N-1/N-2]. 
19. A UCD group number can be assigned as the destination station of OFF-HOOK ALARM [O-6],
PRIORITY CALL [P-9], ATTENDANT NIGHT TRANSFER [A-19], and LDN NIGHT CONNECTION
[L-28, 29]. 
20. If a Phantom Number is assigned to a controlling station, UCD hunting may or may not occur (depending
on the APHN command setting), when the Phantom Number is dialed.
21. Three types of traffic measurements can be provided for the UCD feature: 
a.) UCD route peg count:
 Count of incoming calls from each route to each UCD group 
 Count of calls answered by UCD
 Count of other calls (abandoned, restricted, blocked) 
Example:
b.) UCD Group peg count:
 Count of incoming calls to each UCD group 
 Count of answered calls 
 Count of other calls (abandoned, restricted, blocked)

Example:
c.) UCD station peg count:
 Count of incoming calls to each station in each group 
 Count of answered calls 
 Count of other calls (abandoned, restricted, blocked) 
Example:
22. UCD Peg counts are available for calls transferred to the UCD group by the Attendant and for calls
transferred to the UCD group from a station.
23. The total numbers of incoming calls for which the UCD queueing feature is available, and other incoming
calls such as intra-office, tie line, etc., are as follows:
1 IMG, 4 IMG system 384 calls/system maximum
IMX-U (16 IMG) system 640 calls/system
Calls above this limit are terminated by a busy tone connection.
24. During queueing block, the ATTENDANT CAMP-ON WITH TONE INDICATION [A-1] is valid. The
attendant hears reorder tone when the ATTENDANT CAMP-ON WITH TONE INDICATION [A-1] is
restricted.
25. OVERFLOW-UCD [O-13] is available.
26. When a UCD controlling station transfers the in-progress station call or trunk call to a station which has
been set CALL FORWARDING-ALL CALLS [C-5] or CALL FORWARDING-BUSY LINE [C-2]
whose forwarding destination is the UCD controlling station, these features are valid.
27. When UCD queueing is not available and the system data ASYD SYS 1 INDEX 60 bit 3 = 1 assigned,
UCD peg count is not activated.
28. When the controlling station transfers the station/trunk to another station that has set CALL
FORWARDING - ALL CALLS [C-5] or CALL FORWARDING - BUSY LINE [C-2] (to the same
controlling station), call forwarding is activated and the MCI message is sent out.
29. Whether UCD incoming call information is to be sent to a Message Center Interface (MCI) or not can be
specified on a UCD group basis using the AUCD command. This feature can be assigned to each UCD
Group. In the case of UCD incoming calls overflowing to a UCD Group, the judgement whether the
information is to be sent to MCI or not depends on the terminated UCD Group.
30. When OVERFLOW - UCD [O-13] is activated, the transferred destination’s data decide whether UCD
incoming call information is sent to MCI or not.

31. This feature is available via FCCS link.
32. A UCD Group for FCCS service is not available for the destination of the dead level or the dead number.
33. The following number is assignable to a station of the UCD group.
a.) Physical Station Number (Physical Station Number, Phantom Number, Monitored Number [Pilot
No.], DTE station)
b.) Telephone number
34. When activating this feature via the FCCS network, only the telephone number is available for FCCS
service.
35. When activating this feature via the FCCS network, the maximum number of the UCD groups in a node
is 63.
36. When activating this feature via the FCCS network, the station assigned by using the Physical Station
Number and the station assigned by using the telephone number cannot be accommodated in the same
group and the same node.
37. When activating this feature via the FCCS network, the maximum number of stations per group are as
shown below:
Physical Station Number: 100 stations
Telephone Number: 100 stations
38. When activating this feature via the FCCS network, two types of UCD groups are available:
Group (a): All the stations belonging to one group are accommodated in the same node.
Group (b): Stations belonging to one group are accommodated in different nodes.
Group (a) and Group (b) can be used together within a FCCS network.
39. When using the FCH card in conjunction with FCCS link:
a.) Stations in four different nodes can be assigned in a UCD group.

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.

U-3 Universal Sender
U-3 Universal Sender
General Description
This feature permits dialed numbers to be transmitted via a sender, a device that will automatically add or delete the
necessary number of digits or perform any necessary conversions.
Operating Procedure
No manual operation is required.
Service Conditions
1. For incoming connections, digits may be deleted according to the route involved. A maximum of 4 digits
may be added (including the access code).
2. For outgoing connections, digits may be added/deleted according to the route involved. A maximum of 24
digits may be deleted, and a maximum of 4 may be added (including the access code).
3. LEAST-COST ROUTING [L-5]: Digits may be added/deleted according to the route involved and the
dialed digits. A maximum of 24 digits may be deleted, and a maximum of 24 may be added, consisting of
either digits or 2.8 second pauses.
Interactions
1. For features requiring digit translation, refer to the specific feature programming description.
2. The ASTP, AOSP, and AISP commands operate to translate incoming TIE Line digits that are received
by the register and then sent to the opposite PBX via UNIVERSAL SENDER. The ANND command is
used like the AMND command. It tells the system how many digits the register is to expect for a specific
route. The UNIVERSAL SENDER then sends the digits to the opposite PBX. 
Features requiring the UNIVERSAL SENDER are:
ATTENDANT CONSOLE [A-3] 
ATTENDANT KEY PAD [A-4] 
AUTOMATIC TRUNK TEST [A-21] 
CALL FORWARDING-OUTSIDE [C-28]
