PIN ASSIGNMENTS

Straight-Through Wiring

If the twisted-pair link segment is to join two ports and only one of the ports has an internal crossover, the two pairs of wires must be straight-through.

Crossover Wiring

If the twisted-pair link segment is to join two ports and either both ports are labeled with an “x” or neither port is labeled with an “x,” a crossover must be implemented in the wiring.
