Table 27 WAN Backup (continued)
LABEL	DESCRIPTION
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.
	Note: If you activate traffic redirect, you must configure at least one
	Check WAN IP Address.
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".
Backup Gateway	Type the IP address of your backup gateway in dotted decimal notation. The
	Prestige automatically forwards traffic to this IP address if the Prestige's Internet
	connection terminates.
Dial Backup
Active	Select this check box to turn on dial backup.
	Note: If you activate traffic redirect, you must configure at least one
	Check WAN IP Address.
Metric	This field sets this route's priority among the three routes the Prestige uses (normal,
	traffic redirect and dial backup). Type a number (1 to 15) to set the priority of the dial
	backup route for data transmission. The smaller the number, the higher the priority.
	If the three routes have the same metrics, the priority of the routes is as follows:
	WAN, Traffic Redirect, Dial Backup.
Port Speed	Use the drop-down list box to select the speed of the connection between the dial
	backup port and the external device. Available speeds are: 9600, 19200, 38400,
	57600, 115200 or 230400 bps.
User Name	Type the login name assigned by your ISP.
Password	Type the password assigned by your ISP.
Pri Phone #	Type the first (primary) phone number from the ISP for this remote node. Some
	areas require dialing the pound sign # before the phone number for local calls.
	Include a # symbol at the beginning of the phone numbers as required.
Advanced Setup	Click this button to display the Advanced Setup screen and edit more details of
	your WAN backup setup.
Back	Click Back to return to the previous screen.
Apply	Click Apply to save the changes.
Cancel	Click Cancel to begin configuring this screen afresh.
