EW50 Industrial LTE Cellular Gateway
33
Manually:
This gateway will not start to establish
a WAN connection until the “Connect” button in
web UI is pressed. After normal data transfer
between LAN and WAN sides, this gateway will
disconnect if idle time reaches value of
Maximum Idle Time
.
Note: If the WAN interface serves as the primary one for another WAN interface in Failover role, the
Connection Control parameter will not be available on both WANs as the system must set it to “Auto-
reconnect”.
Network Monitoring
When it is necessary to monitor connection status
continuously, "ICMP Check" and "FQDN Query" are used.
When there is high connection traffic, checking packets
will waste bandwidth, and the response time of replied
packets may also increase. To prevent "Network
Monitoring" from working abnormally, enabling the
"Checking Loading" option will stop connection checking
when there is high traffic. It will wait for another "Check
Interval" and then check loading again.
When you do “Network Monitoring”, if the reply time is
longer than "Latency" or no response time is longer than
"Checking Timeout", the "Fail" count will be increased. If
it is continuous and "Fail" count is more than the
configured "Fail Threshold", the gateway will do an
exception handling process and re-initialize the
connection again. Otherwise, network monitoring process
will restart.
