Straight-through cable
Both 2 RJ45 connectors of the straight-through cable use the same line order. In general, they
follow the EIA/TIA568B standard.
Figure 2-14 shows the line order of the straight-through cable.

Crossover cable
The line order 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/TIA568A standard; the
other RJ45 connector follows EIA/TIA568B standard line order. Figure 2-15 shows the line
order of the 100 Mbit/s crossover cable.
