Digi Connect WAN GSM, a wireless WAN gateway, provides high-performance
wireless TCP/IP data communications via cellular GSM networks for primary and
backup connectivity to remote locations. It utilizes General Packet Radio Service
(GPRS)/Ehanced Data Rates for GSM Evolution (EDGE) to offer an easy and
cost-effective means of connecting virtually any remote location into the corporate
IP network. It is ideal for use where wired networks (e.g., lease line/frame relay,
CSU/DSU, fractional T1) are not feasible or where alternative network connections
are required.

Benefits of wireless communications via Digi Connect WAN GSM include instant
deployment, elimination of wiring costs and problems due to wire breaks, the ability
to traverse firewalls, and the ability to move the connection virtually anywhere.

Digi Connect WAN GSM seamlessly integrates with the
Digi Connectware Manager platform, which provides easy setup, configuration and
maintenance of large installations. Users can upgrade firmware or change settings
of thousands of devices with only a few clicks. Digi Connectware Manager also
makes troubleshooting simple by reporting problems like issues with signal
strength and reconnects.

Digi Connectware Manager, part of the Digi Connectware Suite, provides enterprise class
management and administration to its remote site management class of products, including
Digi Connect WAN GSM. It can be hosted at a customer’s central data center or via a Digi
ASP partner, and can be accessed securely from anywhere across a wired or wireless IP
network, including the Internet.

One of the key benefits of using the Digi Connectware Manager platform is the reduction of
administrative maintenance costs. Fewer maintenance trips are required to remote locations
because of its ability to diagnose and solve problems from the central data center. Another key
time saver is the ability for the system to report problems in the field, instead of having to
dedicate an administrator to constantly monitor all of the devices.

In addition to the Connectware Manager, the Digi Connectware Suite also includes a
connection manager that provides a means of seamless connections to remote devices,
including devices on private or dynamic IP networks.
