D.2 10/100/1000 BaseT (GbE) Interface Module
Figure D-2. 10/100/1000 BaseT (GbE) Interface Module (AS/11984)
The 10/100/1000 BaseT Ethernet – or Gigabit Ethernet (GbE) – Interface Module (Figure D-2),
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 'J5 Ethernet' port of the Base
Modem.
The GbE Interface supports data rates from 64 kbps to 155.52 Mbps. IP traffic entering the
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 per Table D-1.
D.2.1 Physical Description
The 10/100/1000 Base GbE Interface Module is implemented on a PCB. Connectivity to the SLM-
5650A is accomplished with a 96-pin DIN receptacle. The functional block diagram is shown in
Figure D-3. Figure D-2 shows the rear panel view of the module. The LAN interface consists of an
RJ-45 connector with link status and link activity LED indicators.
