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 for current or newly discovered PVC Connections and Management PVCs.

This feature is already set up, with Single_Site_Backup as the default for units with

aBRI DBM and Multi_Site_Backup for units with a PRI DBM. If the unit at the central site has a BRI DBM, change the Automatic Backup Configuration to Multi_Site_Backup, if necessary.
