Straight-Through Wiring
If twisted-pair cable is to join two ports and only one of the ports has an
internal crossover (MDI-X), the two pairs of wires must be
straight-through. (When auto-negotiation is enabled for the RJ-45 port on
the CPE, you can use either straight-through or crossover cable to connect
to any device type.)
