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.
Configuring Backup
The following menus support 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.
