Motorola Router 6161252-00-01 ユーザーズマニュアル

Motorola Netopia® Embedded Software Version 8.7.4 offers line backup functionality in the event of a line 
failure on the primar y WAN link: 

to an internal V.92 modem (suppor ted models) or 

to a backup default gateway. 

This chapter covers the following topics:

The purpose of line backup is to provide a recover y mechanism in the event that the primar y 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 primar y 
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 primar y connectivity you have the option of switching 
back to the primar y por t automatically once it has recovered its connection.

The following menus suppor t 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
