Automatic Backup. Controls automatic initiation of a call setup attempt upon failure of the DDS network, defined as detection of No Signal or

Enab | Ð | Upon detecting a failure of the DDS network, the DSU waits for a period equal to DDS T imeout, and if the |
|
| DDS network is still down, it attempts to establish a dial backup connection to the number specified by |

| the Backup Directory pointer after the Network |
Disab | Ð | 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 through 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 Ð Produces a data entry display for changing the directory entry identifier.
BckupOnCMI:Disab
Next Enab Disab Prev
Backup on Control Mode Idle. 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 | Ð | Upon detecting CMI for 250 to 500 milliseconds from the network, the DSU attempts to establish a dial |
|
| backup connection to the router after the DDS |
|
| Facility Alarm (FA). Do not use this configuration option if the DSU is configured to generate CMI. |
Disab | Ð | 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.
When DTRCallCon is enabled (set to Orig or Ansr), disable AutoRestor.
