Twisted-Pair Cable/Connector

Pin-Outs

Twisted-Pair Cable for Hub-to-Computer

Network Connection

To connect PCs or other network devices to the hub, use a “straight-through”

10Base-T cable. The twisted-pair wires must be twisted through the entire

length of the cable. The wiring sequence must conform to AT&T 258A (not

USOC). See “Twisted-Pair Cable Pin Assignments” later in this chapter for a

listing of the signals used on each pin.

Note

Pins 1 and 2

must

be a twisted pair.

Pins 3 and 6

must

be a twisted pair.

Pins 4, 5, 7, and 8 are not used in this application, although they may be

wired in the cable.
