Figure 3-10. Dial Backup

Under normal backup conditions, when a problem occurs on the primary leased line, the modems establish a connection over the backup network.

Call Setup:

Dial Standby

F1 F2 F3

When this occurs, Dial Standby appears on the LCD in the Call Setup menu branch. If you select Dial Standby, the modem switches back to the primary leased line while still maintaining the backup connection. As a result, Return_to_Dial appears on the LCD instead of Dial Standby.

Call Setup:

Return_to_Dial

F1 F2 F3

If the primary leased line is unacceptable, select Return_to_Dial which switches the modem back to backup network operation (LCD displays Dial Standby). If, however, the primary leased line is operating properly, select Disconnect from the Call Setup branch to drop the dial backup connection. Also, if the primary leased-line operation is maintained uninterrupted for the amount of time specified in the Dial Standby configuration option, the dial backup network disconnects.

To access Dial Standby or Return to Dial from the Call Setup branch, make the following selections:

Call Setup:
