External Modem
The following Dial Backup Configuration page is displayed during Dial Backup configuration if you selected External Modem for the connection.
To configure the external modem for dial backup:
1.In Backup Failover Timeout, enter the number of minutes that must pass during a WAN link failure before switching to the backup port. This guards against too frequent switching back and forth between the DSL link and the backup port. The default minutes is 3.
2.In Retry DSL Timer, enter the number of minutes that must pass before checking to see if the DSL link has been restored.
3.IP Addresses lists the addresses the router uses to ping via the DSL link. If the ping tests fail, the router switches data traffic to the backup port until the retry period expires again.
4.In Ping Success Rate, enter the ping success rate that must be met. As soon as the success rate falls below this number, DSL Link failure is assumed and switch over to backup is performed. This success rate applies to all addresses in the IP Addresses list.
5.In Modem Initialization String, enter the number provided by the modem manufacturer. This number should be found in the modem documentation.
6.Select the data rate for the serial port from the Serial Port Data Rate
7.In Modem Dial String, select Tone Dialing, Pulse Dialing, or specify an Other to control how the modem is dialed.
8.Click Save and Reboot.
