Line Backup

Netopia Firmware Version 8.4 offers line backup functionality in the event of a line failure on the primary WAN link:

•to an internal V.92 modem (supported models) or

•to a backup default gateway.

This chapter covers the following topics:

•“Configuring Backup” on page 7-1

•“Connection Profiles” on page 7-2

•“WAN Configuration” on page 7-8

•“Using Scheduled Connections with Backup” on page 7-12

•“Backup Default Gateway” on page 7-14

•“Backup Management/Statistics” on page 7-17

•“QuickView” on page 7-18

The purpose of line backup is to provide a recovery mechanism in the event that the primary connection fails. A failure can be either line loss, for example by central site switch failure or physical cable breakage, or loss of end-to-end connectivity. Detection of one of these failures causes the router to switch from using the primary DSL WAN connection to using a built-in V.92 modem. Alternatively, you can choose backup to an alternate gateway on the Ethernet LAN. In the event of a loss of primary connectivity you have the option of switching back to the primary port automatically once it has recovered its connection.

•the Add Connection Profile menus under the WAN Configuration menus
