Cables and Connectors
Twisted-Pair Cable/Connector Pin-Outs
These additional rules apply:
All twisted-pair wires used must be twisted through the entire
length of the cable. The wiring sequence must conform to the
ANSI/TIA/EIA-568-B cable specification. See "Twisted-Pair Cable
Pin Assignments" later in this appendix for a listing of the signals
used on each pin.
For 10 Mbps connections to the ports, you can use Category 3, 4,
or 5 unshielded (UTP) or shielded (STP) twisted-pair cable, as
supported by the IEEE 802.3 Type 10Base-T standard.
For 100 Mbps connections to the ports, use 100-ohm Category 5
UTP or STP cable only, as supported by the IEEE 802.3u Type
100Base-TX standard.
