Data Assignment
Incoming DID numbers can be routed to any station or tenants (main
software release 2 and above) in the system regardless of the
numbering plan. If an incoming DID number is invalid, the call can be
sent to a preassigned station or hunt group pilot number.
Two different DID digit modification choices are available:
1. A maximum of two digits can be added and/or deleted from the
incoming DID digits provided by the DID trunk for incoming
address signalling. This is selectable by System Programming per
Trunk Group. [Memory Block 5-00 (Digit Add/Del for Tie Line
Networking Assignment.]
2. DID Full Digit Modification collects the incoming digits and sends
the call to a specified station number.
If a DID incoming call is not answered before a time specified in
Memory Block 1-1-07 (Tie Line Delay Ringing Time Selection), the call
can switch to normal Day or Night ringing assignment (default:
No Timeout).
