A CAT 3, 4 or 5 UTP (unshielded twisted pair) cable is typically used to
connect the Ethernet device to the Modem. A 10Base-T cable often consists
of four pairs of wires, two of which are used for transmission. The connector
at the end of the 10Base-T cable is referred to as an RJ-45 connector and it
consists of eight pins. The Ethernet standard uses pins 1, 2, 3 and 6 for data
transmission purposes.
