The following table describes the fields in this screen.

Table 27   WAN Backup

Backup Type 

Select the method that the Prestige uses to check the DSL connection. 
Select DSL Link to have the Prestige check if the connection to the DSLAM is up. 

Select ICMP to have the Prestige periodically ping the IP addresses configured in 

the Check WAN IP Address fields.

Check WAN IP 

Address1-3

Configure this field to test your Prestige's WAN accessibility. Type the IP address of 

a reliable nearby computer (for example, your ISP's DNS server address). 

Note: If you activate either traffic redirect or dial backup, you must 
configure at least one IP address here. 

When using a WAN backup connection, the Prestige periodically pings the 

addresses configured here and uses the other WAN backup connection (if 

configured) if there is no response.

Fail Tolerance

Type the number of times (2 recommended) that your Prestige may ping the IP 

addresses configured in the Check WAN IP Address field without getting a 

response before switching to a WAN backup connection (or a different WAN backup 

connection).
