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.
