Crossover cable
Wiring of the 100 Mbit/s crossover cable is different from that of the 1000 Mbit/s crossover
cable.
One RJ45 connector of the 100 Mbit/s crossover cable follows EIA/TIA568A wiring; the
other RJ45 connector follows EIA/TIA568B wiring.
Figure 3-5 shows wiring of the 100 Mbit/s crossover cable.
