(GbE) INTERFACE
12.1 Introduction
Figure 12-1. 10/100/1000 BaseT (GbE) Interface Module (AS/11985)
The 10/100/1000 BaseT Ethernet – or Gigabit Ethernet (GbE) – Interface Module, shown in
Figure 12-1, 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 BaseT remote port of
the modem. A functional block diagram is shown in Figure 12-2.
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
CRS-16 verification is performed on all received (from WAN) HDLC frames. The GbE module
user interface is a single IEEE 802.3ab 1000 BaseT 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-5650A 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.
