• B-Channel to Trunk Association
When an Incoming ISDN-BRI/PRI call is received, the system assigns the lowest trunk number of
the ISDN circuit to the incoming call associated with the B-Channel. When an Outgoing call is
placed using the ISDN-BRI/PRI, the system assigns the Trunk and B-Channel association according
to the chart below. This is based on the Trunk-to-Trunk Group and Trunk Group Priority assignment
in (PRG 14-05-01).
Refer to the charts below for examples(23B):
