Appendix A: Cable Requirements

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.
