Chapter 1 Overview

IEEE 802.3 10BaseT Specifications

Table 1-1 summarizes the characteristics of IEEE 802.3 Ethernet and Ethernet Version 2 for 10BaseT.

Table 1-2 lists the cabling specifications for 10-Mbps transmission over UTP and foil twisted-pair (FTP)

cables.

Note The IEEE 802.3 Ethernet specifications call the PA-8E an end station, and the PA-8E has a built-in

transceiver. The PA-8E interfaces connect directly to a hub or repeater.
