DESCRIPTION
Backup Type
Select the method that the device uses to check the DSL connection. 
Select DSL Link to have the device check if the connection to the DSLAM is 
up. Select ICMP to have the device periodically ping the IP addresses 
configured in the Check WAN IP Address type fields.
Check WAN IP 
Address1-3
Configure this field to test your device's WAN accessibility. Type the IP 
address of a reliable nearby computer (for example, your ISP's DNS server 
address). 
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 device 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 device 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).
