Setting Up Automatic Backup Configuration
Only applicable to a FrameSaver 9126 or 9128, the Automatic Backup Configuration
feature is used to automatically create alternate DLCI records and PVC connections on
the ISDN DBM (backup) interface when there is a failure of the primary link or DLCI, or

the remote unit.
Automatic backup can be changed at any time via the Auto Backup Criteria
configuration options. Specific days and times that backup will be allowed can also be
specified. The following table describes what happens when Auto Backup is enabled or
