Check 

Mechanism

Select the method that the ZyXEL Device uses to check the DSL connection.
Select DSL Link to have the ZyXEL Device check if the connection to the DSLAM is 

up. Select ICMP to have the ZyXEL Device periodically ping the IP addresses 

configured in the Check WAN IP Address fields.

Check WAN IP 

Address1
Check WAN IP 

Address2
Check WAN IP 

Address3

Configure this field to test your ZyXEL Device's WAN accessibility. Type the IP 

address of up to three reliable, nearby computers (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 ZyXEL Device periodically pings the 

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

configured) if there is no response.

KeepAlive Fail 

Tolerance

Type the number of times (2 recommended) that your ZyXEL 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).

Recovery 

Interval(sec)

When the ZyXEL Device 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 ZyXEL Device to wait 

between checks. Allow more time if your destination IP address handles lots of 

traffic.

ICMP 

Timeout(sec)

Type the number of seconds (3 recommended) for your ZyXEL Device 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 

ZyXEL Device 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

This feature is disabled in 2wire-2line service mode.

Dial Backup

This feature is disabled in 2wire-2line service mode.

When you have completed this menu, press [ENTER] at the prompt “Press ENTER to Confirm…” to
