M2M Cellular Gateway
USB 3G/4G WAN: The gateway has one USB port that can support 3G/4G USB modem
connection. Please plug 3G/LTE USB dongle and follow UI setting to setup.
ADSL WAN:
The gateway has one ADSL
connection, please plug in RJ11 cable (normally the landline phone cable) in DSL port and follow
UI setting to setup.
Operation Mode
There are three option items "Always on", "Failover", and "Disable" for the operation mode
setting.
Always on: Set this WAN interface to be active all the time. Only the interfaces with "Always on"
operation mode can share their bandwidth for load balance function. That means when two or
more Internet connections are established simultaneously at "Always on" mode, outgoing data
will be transferred through these WAN connections base on load balance policies. This mode is
especially suitable for high bandwidth requirement, such as video stream transmission.
Failover:
A failover interface is a backup connection to the primary. That means only when its
primary WAN connection is broken, the backup connection will be started up to substitute the
primary connection. In addition, there is a "Seamless" option for Failover operation mode. When
seamless option is activated by checking on the "Seamless" box in configuration window, both the
primary connection and the failover connection are started up after system rebooting. But only
the primary connection executes the data transfer, while the failover one just keep alive of
connection line. As soon as the primary connection is broken, the system will switch, meaning
failover, the routing path to the failover connection to save the dial up time of failover connection
since it has been alive.
Disable: Set this WAN interface to be inactive.
Failover Scenario without Seamless:
As an example, you can set the operation mode of WAN‐2 interface to be a backup WAN
connection. WAN‐1 interface serves as the primary connection of WAN‐2 and its operation mode
is "Always on". But the "Seamless" box is unchecked. That means WAN‐2 failover from WAN‐1 and
it won't be activated until primary WAN connection (WAN‐1) has failed. When the primary
interface is recovered back with a connection, primary interface will take over data transfer again.
Following 4 tables list the parameter configuration for these two WAN interfaces.
