Issue 5 October 2002 1683555-233-506

Screen 308. Signaling Group screen (Group 3) — Facility Associated

Signaling

Note the following details in the Signaling Group screens shown above:

■ Signaling Group 1 B-channels on DS1 circuit packs (boards) B0 and B1 are

signaled by D-channel pair B1524 (see the Primary D-channel field) and

B1624 (see the Secondary D-channel field).

■ Signaling Group 2 B-channels on board B1 are signaled by D-channel

B1824.

■ Board B0 has no D-channel. The B-channels on board B0 can be signaled

by either D-channel pair B1524/B1624 (Signaling Group 1) or D-channel

B1824 (Signaling Group 2).

■ The DS1 interface on board B19 (Signaling Group 3) is a Facility

Associated Signaling case. Note that the Secondary D-channel and Trunk

Board/Interface ID fields are not displayed when the Associated Signaling

field is

The following 2 communications-interface screens must be completed for the

ISDN-PRI interface on DEFINITY SI configurations if the D-channel is switched

through the TN765 Processor Interface (PI) circuit pack:

■ Interface Links screen — Used to create an association between the

D-channel on a DSI circuit pack and the port on a TN765 Processor

Interface circuit pack used for this link.

■ Processor Channels screen — Used to assign processor channels to the link

administered on the Interface Links screen.

Finally, trunk ports are added to the ISDN-PRI trunk group and to Signaling

Groups.
