• B-Channel to Trunk Association
When an Incoming ISDN-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-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):
