Line Backup 7-1

Chapter 7

Line Backup

The Netopia 3366C-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 7-12

•“Backup Default Gateway” on page 7-14

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 the 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.

Configuring Backup

The following menus support dial backup configuration:

•the Add Connection Profile menus under the WAN Configuration menus

Here you choose Encapsulation Type = PPP, fill out the correct IP Profile Parameters information, select Backup as the Interface Group, and fill out the Telco Options. See “Connection Profiles” on page 7-2.

•the MODEM (Wan Module 2) Setup menu under the WAN Configuration, WAN (Wide Area Network) Setup menus

Here you configure the Internal Modem Setup that governs a number of general behavior settings for the internal V.92 modem. See “WAN Configuration” on page 7-8.

•the Backup Configuration menu under WAN Configuration, Advanced Connection Options

Here you can select Backup is = Automatic, and Recovery is Automatic. See “Backup Configuration screen” on page 7-10.

•the Backup IP Gateway menu item in the IP Setup screen under the System Configuration menu

Here you enter a Backup Gateway IP address. See “IP Setup” on page 7-7. Alternatively, you can choose a different backup gateway device; see “Backup Default Gateway” on page 7-14.
