E.6 GBEI Operational Setups
The CDM-700 GBEI operates as a bridge device and passes traffic between hosts at different
geographic locations on a common Local Area Network (LAN).
The GBEI operates like a network hub device which means it acts like a “direct wire” connection
and passes all Ethernet traffic and broadcasts. Figure E-4 is an example of using the GBEI to
bridge a remote hosts on a common LAN over the satellite.
It also may be desirable to separate the M&C Ethernet port from the traffic on the GBEI port. Figure E-
5 shows an example where the M&C Ethernet port has been assigned an IP address that is NOT on the
common LAN. A router is in place at both locations to isolate access to the M&C port.
