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.)
