COMSPHERE DualFlow Data Service Units

NOTE

Auto Backup and Auto Restor should not be enabled if DTRCallCon is enabled (set to Orig or Ansr).

•Bckup Dir ± Select the call directory identifier

(1 to 10) stored in the DBM's Backup Directory for the telephone number to be dialed.

•AutoRestor ± Select Enab.

When enabled, the DBM automatically restores data to the DDS circuit when service is restored and the amount of time set in RestoreTimOut has expired.

•NtwkTimOut ± Set the amount of time that the DDS circuit must be out of service before a backup attempt is made: from 0:00 (minutes:seconds) to 29:59 (the default is 0:20).

•RestorTimOut ± Set the amount of time that the DDS circuit must be back in service before automatic restoration is attempted: from 1 to 60 minutes (the default is 5 minutes).

•TriesTimeOut ± Specify the overall time limit during which a DBM attempts to establish a dial backup call when Auto Bckup is enabled or when raising DTR initiates a call attempt: from 1 to 60 minutes (the default is 15 minutes).

•MultiCall ± Select Disab.

When enabled, instead of following the normal calling cycle, the DBM cycles through all dial strings contained in its Backup Directory until a call attempt is successful.

Do not enable MultiCall unless more than one telephone number is in the Backup Directory and each successive (i.e., 1, 2, 3, etc.) telephone number is different from the previous entry. Directory entries should be unique.

Understanding Operating Modes

The Backup branch controls operation of the Dial Backup function. The DualFlow DBM has three modes of operation:

•In Idle mode, there is no dialed connection. The DDS circuit is active and carrying user data.

•In Standby mode, the unit has a dialed connection to another DBM or compatible dial backup unit, but has not connected line data to the DBM's DTE port.

•In Dial Backup mode, the dialed circuit is active and carrying user data and diagnostics.

Table 4-2 lists the Backup branch operating modes and explains the effects of each backup command.
