The wiring for 100 Mbit/s crossover cable is different from that of 1000 Mbit/s crossover
cable.
One RJ45 connector of the 100 Mbit/s crossover cable follows EIA/TIA 568A standard; the
other RJ45 connector follows EIA/TIA 568B standard. Figure 5-4 shows the wiring of the 100
Mbit/s crossover cable.
