Dial Backup - Paradyne COMSPHERE 3910 Installation And Operation Manual

COMSPHERE 3900 Series Modems
Under normal backup conditions, when a problem occurs on the primary leased line, the modems
establish a connection over the backup network.
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.
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:
