Line Backup 7-1CCCChhhhaaaapppptttteeeerrrr 7777LLLLiiiinnnneeee BBBBaaaacccckkkkuuuuppppThe Netopia 3366-ENT offers line backup functionality in the event of a line failure on the DSL primary WAN link:• to its internal V.92 modem 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 7-13• “Backup Default Gateway” on page 7-15The purpose of line backup is to provide a recovery mechanism in the event that the primary connection fails. Afailure can be either line loss, for example by central site switch failure or physical cable breakage, or loss ofend-to-end connectivity. Detection of one of these failures causes the router to switch from using the primaryDSL WAN connection to using the built-in V.92 modem. Alternatively, you can choose backup to an alternategateway on the Ethernet LAN. In the event of a loss of primary connectivity you have the option of switchingback to the primary port automatically once it has recovered its connection.Configuring BackupThe following menus support dial backup configuration:• the Add Connection Profile menus under the WAN Configuration menusHere you choose Encapsulation Type = PPP, fill out the correct IP Profile Parameters information, selectBackup as the Interface Group, and fill out the Telco Options.
