GRE
GRE (Generic Routing Encapsulation) tunnel is used to carry
non‐IP packets through an IP Network. Non ‐IP packets, that
are send over the GRE tunnel, need to be first 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 Sierra Wireless AirLink’s modem’s new
software feature provided via ACEmanager, that allows the
users to generate reports from the events that take place. Event
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.

• ACEview, the software for the Raven XE which allows you
to monitor your connections.
• The driver that forms the interface between the Raven XE
and your Windows operating system when using USB
virtual Ethernet or USB virtual serial.
• The firmware that is stored in non‐volatile memory and
