DID ADDRESSING
General Description
This feature allows incoming ISDN-PRI calls to terminate to stations, ATTCON, Automated Attendant, etc.,
based on the Called Party number. Direct Inward Dial trunks will be terminated to preprogrammed destinations
without Attendant assistance.
Operating Procedure
No manual operation is required.
Station Application
Not applicable.
Service Conditions
1. If the network is notified that the destination station for the DID call is busy or a connection-controlled
station, the network gives the calling station a Busy Tone. (This depends upon call forwarding services
being in service.)
2. If the called station is nonexistent, the DID call can be routed to the Attendant Console, another
predesignated station, or to receive Reorder Tone.
3. Refer to the Business Features and Specifications manual for more details of DID service.
