Twisted-Pair Cable/Connector Pin-Outs

Twisted-Pair Cable for Hub-to-Computer Connection

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

Pins 3 and 6 must be wired to a twisted pair.

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

wired in the cable.
