	packs.	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.
