B-channels must be identified by control unit slot and port numbers since they are
not associated with a line/trunk number or a logical ID.
PRI B-channel groups programmed for line routing perform similarly to loop-start
trunks. PRI B-channel groups programmed for dial plan routing perform similarly
to DID trunks.
NOTE:
If more lines than B-channels are assigned to a B-channel group, users
may experience situations where a line that is idle is not able to seize a
B-channel. The user receives a fast busy tone.
