the time interval allowed between each connection check.

DESCRIPTION
Select Enable to have the Zyxel Device use the cellular connection as your WAN or a
backup when the wired WAN connection fails.
This field displays the connection the Zyxel Device would use first when the wired
WAN connection fails. You can choose Ethernet or Cellular as the primary WAN
connection for your Zyxel Device.
Configure this field to test your Zyxel Device's WAN accessibility. Enter the IP address
of a reliable nearby computer (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.
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. Enter 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.
