Call Forwarding - Intercept - CCIS C-48
C-48 Call Forwarding - Intercept - CCIS
General Description
This feature allows calls to an inoperative number, through a CCIS trunk, to be intercepted and routed to a recorded
announcement. This announcement will inform the caller that an inoperative number was dialed and will give the
Listed Directory Number for information.
Operating Procedure
This feature is set in system programming and no manual operation is required.
Service Conditions
1. This feature requires an announcement trunk and an announcement machine at each node.
2. Only one call at a time can be connected to each announcement trunk. If a second call arrives while the
first call is being processed, the caller will receive ringback tone until the trunk becomes idle. This is when
AAED - M = 1.
3. If disconnect timing is programmed in system data and the calling party forgets to hang up, the system will
automatically disconnect from the call after 30 seconds. If no disconnect timing is programmed, the calling
party will control disconnect.
4. This feature is provided on a per-tenant basis.
5. Calls to restricted numbers will receive reorder tone.
6. Only one common message can be provided for all intercept conditions.
7. The following call conditions are routed to CALL FORWARDING-INTERCEPT - CCIS:
• Vacant level
• Unassigned telephone number
Interactions
1. The trunk number will only be required when a multiple connection is assigned.
2. The COT trunk circuit is used to interface a customer-provided announcement machine.
3. The Digital Announcement Trunk (DAT) card may be used for announcements instead of an external
announcement machine. In this case, the COT card is not required.
4. The type of connection to the announcement machine depends on whether the machine provides a battery
reversal at the end of the message. Battery reversal allows for the recycling of the message so that a calling
station will always be connected to the beginning of the message. Therefore, the calling party will continue
to hear ringback tone until connected to the beginning of the announcement.
5. See ANNOUNCEMENT SERVICE [A-15] .
