B-Channel to Trunk Association
When an Incoming ISDN-BRI/PRI call is received, the system assigns the lowest trunk

Outgoing call is placed using the ISDN-PRI/BRI, 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 (Program 14-05-01).
