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.
