Twisted Pair Cables

For two devices to communicate,the transmitter of each device must be connected

to the receiver of the other device.The crossover function is usually implemented

internally as part of the circuitry in the device.Computers and workstation adapter

cards are usually media-dependent interface ports,called MDI or uplink ports.

Most repeaters and switch ports are configured as media-dependent interfaces with

built-in crossover ports, called MDI-X or normal ports.

Figure C-1 illustrates straight-through twisted pair cable.

Key:

A = Uplink or MDI port (as on a PC)

B = Normal or MDI-X port (as on a hub or switch)

1,2,3,6 = Pin numbers
