Dial Backup Config
Under DBU CONFIG, the menu items are:
Backup Mode
In a backup condition, both ends of the circuit must detect backup conditions before backup is activated. One DBU is set to ORIGINATE and the other to ANSWER. Upon a network failure, only the Originate DBU initiates backup by dialing the ANSWER END. Once called, the ANSWER DBU goes into backup mode only if a backup condition is detected. This is ideal for controlling where calls originate.
Choices: DISABLE, ORIGINATE, ANSWER
Backup On
Selects the conditions that cause the Nx/DBU to ini- tiate Backup.
NET FAIL
Backup occurs on RED ALARM, YELLOW ALARM, BLUE
ALARM and LOS.
