Transfer Max
Rate(Kbps)
This field is enabled if Service Type is Server . Press [SPACE BAR] to set the
maximum rate at which the ZyXEL Device sends and receives information. If you
enable Rate Adaption , the ZyXEL Device adjusts to the speed of the other device
and may exceed this rate.
Transfer Min
Rate(Kbps)
This field is enabled if Service Type is Server . Press [SPACE BAR] to set the
minimum rate at which the ZyXEL Device sends and receives information. If you
enable Rate Adaption , the ZyXEL Device adjusts to the speed of the other device
and may transfer information at less than this rate.
Standard Mode This field is enabled if Service Type is Server . Press [SPACE BAR] to select the
operational mode the ZyXEL Device uses in the DSL connection.
Wan Backup
Setup
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 Press [SPACE BAR] to select Yes and then press [ENTER] to activate traffic redirect
and to edit its settings.
Dial Backup Press [SPACE BAR] to select Yes and then press [ENTER] to activate the dial-
backup interface and to edit its settings.
When you have completed this menu, press [ENTER] at the prompt “Press ENTER to Confirm…” to
save your configuration, or press [ESC] at any time to cancel.
