Call Waiting Lamp - UCD C-76
C-76 Call Waiting Lamp - UCD
General Description
This feature uses an LED indication, which is one of the programmable keys on the D
term
, to indicate when a call is
waiting to be answered in the UCD queue.
Operating Procedure
No manual operation is required.
Service Conditions
1. The UCD Call Waiting Lamp displays the status of the UCD group as follows:
Lamp On: One or more calls waiting in the UCD queue.
Lamp Flashing: More than the pre-assigned number of calls are waiting in the UCD queue.
Lamp Off: No calls are waiting in the UCD queue.
2. The number of calls waiting in the UCD queue that causes the UCD Call Waiting Lamp to light or flash
can be assigned on a per-UCD group basis through the Maintenance Administration Terminal (MAT).
3. The UCD Call Waiting Lamp indicates the status of the UCD group that the D
term
is assigned to, not the
status of other UCD groups.
4. The UCD Call Waiting Lamp indication lasts as long as calls are in a queue.
5. The lamp must be assigned to a D
term
line/feature key LED through the MAT. A call cannot be answered
by this key. Only the UCD line number key (prime, sub, etc.) can be used to connect a call.
6. The number of UCD groups per system is 63.
7. When an additional D
term
is allowed this service, or when a D
term
data using this service is deleted, the
circuit card that accommodates the port of the D
term
must be initialized.
8. This feature can be programmed in Local data Memory (LDM).
9. When using the FCCS network, this feature is available for UCD stations belonging to the node that
accommodates the UCD controlling station.
10. When using the FCCS network, if the number of UCD calls in the queue is over the threshold value, the
lamps of stations in the same node that the UCD controlling station belongs to, start to flash.
Interactions
1. The lamp will toggle between solid and flashing as the number of calls in the queue increases and
decreases, crossing the threshold value set in AUCD.
2. If the pilot telephone number of a UCD group is set to CALL FORWARDING-ALL CALLS [C-5] to
another UCD group, UCD hunting takes place in the second group. If all stations in the second group are
busy, queuing takes place in the second group and its Call Waiting Lamp will light.
3. ATTENDANT CAMP-ON [A-1] call directed to the UCD pilot station will activate the UCD Call Waiting
Lamp if all stations in the group are busy.
4. CALL WAITING LAMP-UCD is not affected by CALL WAITING-TERMINATING [C-12].
5. CALL WAITING LAMP-UCD is only effective for the MY Line station of a D
term
. Even if another UCD
group appears as sublines on that D
term
, CALL WAITING LAMP-UCD will only function for the UCD
group of the MY Line telephone number.
