From the Dial pop-up menu, you can choose whether to Dial Out Only, Dial In Only, or Dial In/Out (default).

You can add the Number to Dial and an Alternate Site to Dial, if available.

You can toggle Dial on Demand to Yes or No. This allows the router to determine whether or not to dial the backup number when there is traffic that needs to be transmitted or received.

You can set the Idle Timeout (seconds) to tear down the connection after some specified period of inactivity.

You can also toggle Callback to No or Yes. In most cases, since this is a backup connection, you can leave this set to the default No.

Using Scheduled Connections with Backup

The backup link is a PPP dial-up connection and only connects to the Internet service provider when traffic is initiated from the LAN. If you want to use the backup link to provide redundancy for services, such as a Web service that you provide to the outside world, you must force the connection to stay up. You do this by creating a scheduled connection entry that will be a permanent “forced up” connection for the backup port. The backup port will be activated upon primary WAN link failure and remain active until primary WAN link recovery.

To configure a Scheduled Connection, from the Main Menu select WAN Configuration and then Scheduled Connections.
