In the port-to-channel mapping, use the
same channel numbers for both ends of
the trunk.
Each end of the trunk may use different port
numbers on the respective ATM circuit
packs.

and press
Enter; go to screen 6.
The same port numbers on the circuit
packs need not be used on the two ends
of the emulated circuit.
The maximum number of emulated circuits
(signaling groups) on a single TN2305
circuit pack is 8.
A circuit pack can have more than one
signaling group and more than one
D-channel. The D-channel from one
emulated circuit cannot signal for the
bearer channels of another emulated
circuit (no NFAS for virtual circuits).
A minimum of 7 ports must be administered
for each emulated circuit (signaling group).
Because this includes the D-channel, at
least 6 B-channels and the D channel
must be administered in a signaling
group.
