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

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

Call Setup:
Return_to_Dial

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, you can select Disconnect from the Call Setup branch to drop the dial backup
connection. Also, if the primary leased-line operation is maintained uninterrupted amount of time
specified in the Dial Standby configuration option, the dial backup network disconnected.

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

Call Setup:
Dial Standby

Press the

key until Dial Standby or Return_to_Dial appears. Select the appropriate function.

Dial Standby
Command Complete

If the modem is operating in a Dial Backup mode, the Dial Standby function forces the modem to
primary leased-lines and the LCD displays the status message Command Complete.

Once the modem is in Dial Standby mode, Return_to_Dial appears on the LCD. Selecting this
function forces the modem to backup networks and the LCD displays the status message
Command Complete.
