Table 10 summarizes the characteristics of IEEE 802.3 Ethernet and Ethernet Version 2 for 10BASE-T.

Table 10 IEEE 802.3 and 10BASE-T Ethernet Version 2 Physical Characteristics

Parameter	IEEE 802.3 Ethernet	10BaseT Ethernet Version 2
Data Rate (Mbps)	10	10
Signaling method	Baseband	Baseband
Max. segment length (m)	500	100 (UTP)
Media	50-ohm coax (thick)	Unshielded twisted-pair (UTP)
Topology	Bus	Star

Table 11 lists the cabling specifications for 10-Mbps transmission over UTP and STP cables.

Table 11 Cable Specifications for 10-Mbps 10BASE-T

Parameter	RJ-45
Cable specification	Category 5 UTP 1, 22 to 24 AWG2
Maximum segment length	100 m (328 ft.) for 10BASE-T
Maximum network length	200 m (656 ft) (with 1 repeater)

1.Cisco Systems does not supply Category 5 UTP RJ-45 cables; these cables are available commercially.

2.AWG = American Wire Gauge. This gauge is specified by the EIA/TIA-568 standard.

The Ethernet specifications call the 4E device a transceiver, and it is connected to the station with a transceiver cable. The 4E port adapter is not an end station. The IEEE 802.3 specifications refer to the same type of device as a media attachment unit (MAU) and to the cable as an attachment unit interface (AUI). Only transceiver cables can connect to the 4E ports directly.
