Setting Up Automatic Backup Configuration
The Automatic Backup Configuration feature is used to automatically create alternate
DLCI records and PVC connections on the ISDN DBM (backup) interface. This feature
should be disabled for the central site unit, but enabled for the remote unit, usually the
unit originating the call.
To enable this feature:
1. Enable the Automatic Backup Configuration feature at the remote site so alternate
routes can be configured for data, as needed.
