This section describes how to identify a crossover cable and also describes the
adapter pinouts.
To identify a crossover cable, compare the two modular ends of the cable. Hold
the cable ends side-by-side, with the tab at the back. The wire connected to the
pin on the outside of the left plug should be the same color as the wire connected
to the pin on the outside of the right plug. (See
