Appendix E. 10/100/1000 Base-T
(GbE) Interface
E.1 Introduction
The 1000 Base-T Ethernet Interface or GbE acts as an Ethernet bridge for data traffic. The GbE
Interface is shown in Figure E-1. Monitor and Control (M&C) information is not supported on
the GbE Interface but is available through the 10/100 Base-T remote port of the modem. The GbE
Interface is 10/100/1000 Base-T and supports data rates from 1 Mbps to 155 Mbps. IP traffic
entering the GbE Interface is encapsulated in HDLC protocol for transmission over the satellite
link. HDLC CRS-16 verification is performed on all received (from WAN) HDLC frames. The
user interface to the GbE card is a single IEEE 802.3ab 1000 Base-T copper compliant female
RJ-45 connector wired as described in Table E-1.
