Backup Configuration Options
Auto Bckup:Disab
Next Enab Disab Prev
Automatic Backup. Controls automatic initiation of a call setup attempt to a remote DBM or modem upon
failure of the DDS network, defined as detection of No Signal or Out-of-Service codes, MUX Out-of-Frame
Threshold, or excessive bipolar violations. (Automatic dial attempts begin after the Network Time-out
expires.)
Enab — Upon detecting a failure of the DDS network, the DSU waits for a period equal to DDS
Timeout, and if the DDS network is still down, it attempts to establish a dial backup connection
to the remote DBM specified by the Backup Directory pointer after the Network Time-out
expires.
Disab — No automatic attempt is made to establish a dial backup connection.
Backup Dir: 1
Next Chang Prev
Backup Directory. The DBM can store 10 dial strings or telephone numbers, identified by the numbers
1—10. This display shows the identifier of the current default dial string to be used to set up a dial backup
call for automatic backup as described in the Auto Bckup configuration option or when the backup command
is received from the DCP or the NMS.
Chang — Produces a data entry display for changing the directory entry identifier.
BckupOnCMI:Disab
Next Enab Disab Prev
Backup on Control Mode Idle.
1
This configuration option determines whether the DSU treats a control mode
idle (CMI) condition as a facility alarm to trigger automatic dial backup. Configuration option Auto Bckup
must be enabled.
Enab — Upon detecting CMI for 250 to 500 milliseconds from the network, the DSU attempts to
establish a dial backup connection to a remote DSU after the DDS Time-out expires. When
enabled, CMI will also generate a Facility Alarm (FA). Do not use this configuration option if the
DSU is configured to generate CMI.
Disab — No attempt is made to establish a dial backup connection if CMI is detected.
AutoRestor:Disab
Next Enab Disab Prev
Automatic Restoration. Controls whether the DSU automatically terminates the dial backup call when the
DSU determines that the DDS circuit has been returned to service.
On point-to-point circuits, a Digital Test is run to verify the DDS network. If the Digital Test is successful, user
data is switched back to the DDS circuit.
For a multipoint network with dedicated multipoint dial backup, each of the tributaries may be configured for
Automatic Restoration. Automatic Restoration will not occur unless the backup was initiated by the tributary.
The DDS network is not verified before data is switched back to the DDS network.
Enab — Restoral of the DDS circuit triggers automatic restoration (after the Restoration Time-out
expires).
Disab — Restoral of the DDS circuit does not trigger automatic restoration.

The remote DSU must be configured for RTS Cntrl = FrcOn.
