Legend: BI_D = bidirectional; A, B, C, D = wire pairings
10Base-T Ethernet and 100Base-T fast Ethernet use the same two pairs of wires. The twisted pair of wires
connecting to pins 1 and 2 transmit data, and the twisted pair connecting to pins 3 and 6 receive data.
1000Base-T connections use all four twisted-pair wires for bidirectional traffic.
