C-164 CCIS Tandem Call - Calling Party Number
(CPN) Delivery to ISDN & Q-SIG Networks
General Description
This feature allows the call from a Tie Line (CCIS line or Q-SIG) station or Attendant Console for INDIVIDUAL
ATTENDANT ACCESS [I-6], to be sent to the public ISDN network (AT&T, NT, NI-2) and Q-SIG network. With
this feature, the calling party number can be changed as programmed and sent to the ISDN network/Q-SIG network.
Since the data can be set to designate the received number in addition to the outgoing route to ISDN network, a
variety of calling party number assignments is available.
Operating Procedure
No manual operation is required.
