Note:
The procedure below describes how to configure ISDN-NFAS trunks on-the-fly. The
configuration process is the same as the initial Offline configuration, but the sequence of
configuring or locking the trunks is important.

To configure ISDN-NFAS Trunks on-the-fly:

Unlocking an NFAS Group:
a. If there is a Backup trunk for this group, it must be unlocked first.
b. The Primary trunk must be unlocked before unlocking any NFAS trunks.
c. NFAS trunks should then be unlocked.

Locking and Removing an NFAS Group:
a. Lock all NFAS trunks, change their Protocol Type to NONE and then unlock them.
b. Lock the Backup trunk if it exists. Change its Protocol Type to NONE and then
unlock it.
c. Lock the Primary trunk, change its Protocol Type to NONE and then unlock it.
Note:
Version 5.8

Figure 5-7: General Settings Window

All trunks in the group must be configured with the same values for trunk
parameters TerminationSide, ProtocolType, FramingMethod and LineCode.
You cannot re-configure an NFAS group after locking it. You must first set all
trunks to Protocol Type NONE and then start configuration again.
