Chapter 12. 10/100/1000BASE-T

12.1 Introduction

The 10/100/1000BASE-T Ethernet – or Gigabit Ethernet (GbE) – Interface acts as an Ethernet
bridge for data traffic. Monitor and Control (M&C) information is not supported on the GbE
Interface, but is available through the 10/100/1000BASE-T remote port of the modem.
The GbE Interface supports data rates from 64 kbps to 155.52 Mbps. IP traffic entering the GbE
Interface is encapsulated in HDLC protocol for transmission over the satellite link. HDLC CRC-16
verification is performed on all received (from WAN) HDLC frames. The GbE user interface is a
single IEEE 802.3ab 1000BASE-T copper compliant female RJ-45 connector, wired as described
in Table 12-1.

12.2 Physical Description

The GbE Interface is implemented on a 4.5 W x 6.8 D x .85 H inches (11.43 W x 17.27 D x 2.16H
cm) PCB. Connectivity to the SLM-5650B is accomplished with a 96-pin DIN receptacle. The LAN
interface consists of an RJ-45 connector with link status and link activity Light-Emitting Diode
(LED) indicators.
