Internal Modem
The following Dial Backup Configuration page is displayed during Dial Backup configuration if you selected
Internal Modem
for the connection.
To configure the internal 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 WAN
link and the backup port. The default minutes is 3.
2. In
Retry WAN Timer
, enter the number of minutes that must pass before checking to see if the Wan line
has been restored.
3.
IP Addresses
lists the addresses the router uses to ping via the WAN 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, Wan 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 Dial String
, select
Tone Dialing
or
Pulse Dialing
to control how the modem is dialed.
6. Click
Save and Reboot
.
