Creating an NFAS-Related Trunk Configuration

The procedures for creating and deleting an NFAS group must be performed in the correct order, as described below.

To create an NFAS Group:
1. If there’s a backup (‘secondary’) trunk for this group, it must be configured first.
2. Configure the primary trunk before configuring any NFAS (‘slave’) trunk.
3. Configure NFAS (‘slave’) trunks.
To stop / delete an NFAS Group:
1. Stop or delete (by setting ProtocolType to 0, i.e., 'None') all NFAS (‘slave’) trunks.
2. Stop or delete (by setting ProtocolType to 0, i.e., 'None') the backup trunk if a backup trunk exists.
3. Stop or delete (by setting ProtocolType to 0, i.e., 'None') the primary trunk.
All trunks in the group must be configured with the same values for trunk parameters TerminationSide, ProtocolType, FramingMethod, and LineCode.
After stopping or deleting the backup trunk, delete the group and then reconfigure it.
