Twisted-Pair Cable and Pin Assignments

Caution: DO NOT plug a phone jack connector into any RJ-45 port.
For 10BASE-T/100BASE-TX connections, a twisted-pair cable must have
two pairs of wires. Each wire pair is identified by two different colors. For
example, one wire might be green and the other, green with white stripes.
Also, an RJ-45 connector must be attached to both ends of the cable.
Caution: Each wire pair must be attached to the RJ-45 connectors in a
Figure B-1 illustrates how the pins on the RJ-45 connector are numbered.
Be sure to hold the connectors in the same orientation when attaching the
wires to the pins.
Use only twisted-pair cables with RJ-45 connectors that
conform with FCC standards.
