Dial Backup
Use the Dial Backup option to configure a backup connection to the Internet through an internal V.90 (model
5835 only) or an external asynchronous modem connected to the console port. This backup connection can be
activated in the event of WAN service interruption. During an interruption to the WAN interface connection, the
router will use the dial backup modem connection while waiting for WAN service to be restored. Once the WAN
link is active again, Dial Backup will automatically switch back to the WAN service.
