GRE
GRE (Generic Routing Encapsulation) is a tunneling protocol used to carry non-
IP packets through an IP Network. Non-IP packets that are sent over the GRE
tunnel must first be encapsulated. Hence, ALEOS is used to configure and
encapsulate non-IP packets and transmit over IP through the GRE tunnel.
Applications
Events Reporting
Events Reporting is a Sierra Wireless AirLink device feature, provided by
ACEmanager, that allows the users to generate reports from the events that take
place. Events Reporting Protocol is an intuitive embedded protocol which
automatically formats the messages based on an event trigger. The messages
generated are then reported to the remote server.
Software
The AirLink GX400 device comes with the following software:
• ACEview, the Windows-based software for the AirLink GX400 which allows
you to monitor your connections
• Drivers for Windows XP and Windows 7 32-bit for the USB virtual Ethernet
and USB virtual serial connections. A 64-bit version is available from Support
at www.sierrawireless.com
• Firmware that is stored in non-volatile memory and includes ACEmanager.
The AirLink GX400 has an embedded radio module made by Sierra Wireless,
Inc. There are two firmware programs on the device—one stored on the con-
troller board of the AirLink GX400 and one on the radio module.
This firmware was loaded into the radio module and controller board when the
AirLink GX400 was assembled. As new versions of the software and firmware
are released, they are posted at www.sierrawireless.com.
