M2M Cellular Gateway

Operation Mode
There are three option items "Always‐on", "Failover", and "Disable" for the operation mode
setting. It decides whether the corresponding WAN interface functions as the main access, as a failover
access connection or disable the interface.

Line Speed
Specify the correct line speed (bandwidth) of uploading and downloading for each WAN interface
allow the device to operate its QoS&BWM and WAN Load Balance functions normally. It is necessary to
configure the parameters if you want to use QoS&BWM and WAN Load Balance functions on the
gateway device.

VLAN Tagging
Sometimes, your ISP required a VLAN tag to be inserted into the WAN packets from Gateway for
specific services. You must specify it in the WAN physical interface. Please note that only Ethernet and
ADSL physical interfaces support the feature.
Interface Configuration
The configuration of a WAN interface includes the settings of interface type, operation mode, line
speed of upload and download, and VLAN tagging. The WAN interface name at the end of window
caption indicates which interface that you are configuring.
The content in above diagram is an example for Ethernet WAN interface.

Physical Interface
AMIT gateway supports Ethernet, 3G/4G, USB 3G/4G and ADSL physical interfaces. The kinds of
physical interface in the device depend on the specification of gateway product purchased.
Following are some physical interface configuration examples and their illustration diagram.
Please be noted that USB 3G/4G can be used only as a failover interface. The primary connection is
WAN‐1 and its operation mode must be "Always on". So, the physical interface of WAN‐1 will not be
"USB 3G/4G".
Index skipping is used to reserve slots for new function insertion, when required.
