	Prestige 792H G.SHDSL Router
	Table 5-2 WAN Backup
LABEL	DESCRIPTION
Backup Type	Select the method that the Prestige uses to check the DSL connection.
	Select DSL Link to have the Prestige check the DSL connection’s physical
	layer. Select ICMP to have the Prestige periodically ping the IP addresses
	configured in the Check WAN IP Address fields.
Check WAN IP	Configure this field to test your Prestige's WAN accessibility. Type the IP
Address1-3	address of a reliable nearby computer (for example, your ISP's DNS server
	address).
	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).
Recovery Interval	When the Prestige is using a lower priority connection (usually a WAN backup
	connection), it periodically checks to whether or not it can use a higher priority
	connection.
	Type the number of seconds (30 recommended) for the Prestige to wait
	between checks. Allow more time if your destination IP address handles lots of
	traffic.
Timeout	Type the number of seconds (3 recommended) for your Prestige to wait for a
	ping response from one of the IP addresses in the Check WAN IP Address
	field before timing out the request. The WAN connection is considered "down"
	after the Prestige times out the number of times specified in the Fail Tolerance
	field. Use a higher value in this field if your network is busy or congested.
Traffic Redirect
Active	Select this check box to have the Prestige use traffic redirect if the normal WAN
	connection goes down.
Metric	This field sets this route's priority among the routes the Prestige uses.
	The metric represents the "cost of transmission". A router determines the best
	route for transmission by choosing a path with the lowest "cost". RIP routing
	uses hop count as the measurement of cost, with a minimum of "1" for directly
	connected networks. The number must be between "1" and "15"; a number
	greater than "15" means the link is down. The smaller the number, the lower the
	"cost".
