En el artítulo Gigabit ethernet over copper with a crossover cable (1000baseT) se explica la forma de grimpar un cable cruzado para que trabaje a 1G.
Según el artículo en 1000baseT usa 4 pares en Cat5 cuando en 100baseTX solamente usa 2 (is that 1000baseT use all four wire pairs available in a Cat5 cable, whereas 100baseTX only uses two wire pairs).
Enjoy!!!
