- Pins 1 and 2 are reversed on the other end of the cable.
- Pins 1 and 2 on one end of the cable connect to pins 3 and 6 on the other end of the cable.
- Pins 1 and 2 on one end of the cable connect to pins 3 and 4 on the other end of the cable.
- The cable can be up to 1000 meters long to cross over between buildings.

Explanation: Crossover cables cross the wire at one node’s transmit pin pair to the different pins used as the receive pins on the other device. For 10- and 100-Mbps Ethernet, the specific crossover cable wiring connects the pair at pins 1 and 2 on each end of the cable to pins 3 and 6 on the other end of the cable, respectively.
