Twisted-Pair Cable for Hub-to-Computer
Network Connection
To connect PCs or other network devices to the hub, use a “straight-through”
Category 3, 4, or 5 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.
