GSP-1620 Satellite Data Modems (SDM). The MCM-4e also includes a Ethernet 10
Base-T port, power supplies, converters, and management functions.
The 10/100 BaseT Ethernet port can be connected to multiple remote client terminals through a
suitable hub or switch. It provides the path through the Globalstar network for your remote client
terminal(s) to communicate. Your connection may be to a public server site or you may be connected
to a private site such as a Virtual Private Network (VPN).
In normal operation the MCM-4e provides you with a PATH to and from the Internet, which allows
your mobile platform to be connected without having wires attached to it. You operate the remote
client terminal exactly the same way you would if it were connected to any other Ethernet LAN. When
the MCM-4e is operating normally, it provides the path to and from the Internet and will be
transparent to you. Refer to figure 2-1 for an overview of the satellite connection.
