Call Forwarding - Intercept / Announcement - Attendant C-75
C-75  Call Forwarding - Intercept / Announcement - 
Attendant
General Description
This feature provides for interception of Attendant-originated calls that cannot be completed (unassigned station,
level, etc.). These calls are automatically routed to a recorded announcement informing the caller that an inoperative
number was reached.
Operating Procedure
No manual operation is required once this feature has been programmed in system data.
Service Conditions
1. This feature requires one of the following hardware alternatives: 
a.) Central Office Trunk (COT) or 2W E&M trunk and an announcement machine. 
b.) Digital Announcement Trunk (DAT).
2. The following connections are available: 
a.) Multi-connection: several Attendants can be connected to the announcement trunk at the same
time.
b.) Single connection: at any given time, only one Attendant can be connected to the announcement
trunk.
3. If the Attendant forgets to cancel a call, the system will automatically disconnect in 30 seconds (provided
this is programmed in system data). If no disconnection timing is programmed, the Attendant will control
disconnection.
4. This feature is provided on a per-tenant basis.
5. This feature is only available on Attendant-originated calls.
6. Only one message can be provided for different intercept conditions.
7. Before connection to the announcement machine is made, the system can be programmed to return
ringback tone.
8. ANNOUNCEMENT SERVICE is provided to FCCS nodes that have no announcement trunk in the
remote node.
9. When CALL FORWARDING-INTERCEPT/ANNOUNCEMENT [C-25] or CALL FORWARDING-
INTERCEPT/ANNOUNCEMENT - ATTENDANT [C-75] is used in an FCCS network, the additional
data shown below is required:
a.) The logical route number should be applied to the physical route that is provided the service.
b.) The restriction of route-to-route connection between FCCS nodes should be released.
10. CALL FORWARDING - INTERCEPT/ANNOUNCEMENT [C-25] or CALL FORWARDING -
INTERCEPT/ANNOUNCEMENT - ATTENDANT [C-75] is not provided for an incoming call using
AUTOMATED ATTENDANT [A-82], DIRECT-IN TERMINATION [D-7], or REMOTE ACCESS TO
SYSTEM [R-2].
11. Call forwarding for an incoming call routed to a dead level or an unused number has priority over the
ANNOUNCEMENT service for incoming calls.

C-76 Call Waiting Lamp - UCD
C-76  Call Waiting Lamp - UCD
General Description
This feature uses an LED indication, which is one of the programmable keys on the Dterm, 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 Dterm data using this service is deleted, the
circuit card that accommodates the port of the Dterm must be initialized.
8. When using the FCCS network, this feature is available for UCD stations belonging to the node that
accommodates the UCD controlling station.
9. 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 Dterm, CALL WAITING LAMP-UCD will only function for the UCD
group of the MY Line telephone number.
6. If OVERFLOW-UCD [O-13] is programmed, overflow to the second group will take place if all stations
in the first group are either busy or in the busy-out state. There will be no CALL WAITING LAMP-UCD
indication to the first group.

Call Waiting Lamp - UCD C-76
Interactions (cont’d)
7. If the overflow group is all busy, queuing takes place to the first group and the CALL WAITING LAMP-
UCD will light to indicate a queuing condition at the first group.
8. When a UCD station is assigned as the destination station of LDN Night Connection, this service cannot
be activated.
9. For the FCCS network, this feature is available only for UCD stations in the same node as the UCD
controlling station. For more information, see UNIFORM CALL DISTRIBUTION [U-1].
