100BASE-TX/10BASE-T Pin Assignments

With 100BASE-TX/10BASE-T cable, pins 1 and 2 are used for

transmitting data, and pins 3 and 6 for receiving data.

Straight-Through Wiring

If the twisted-pair cable is to join two ports and only one of the

ports has an internal crossover (MDI-X), the two pairs of wires

must be straight-through.
