18.1.6.3.3 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.
Notes:
• 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.
