Crossover Cables

When cascading or connecting the hub to another hub, or to a switch or

bridge, through a UTP port, a modified crossover cable is necessary. With a

crossover cable, two pairs of wires are switched at one connector end.

Carry out the following steps to create a customized, crossover twisted-pair

The wiring at just one end of the cable needs to be modified.
