UTP Network Cable wiring scheme

Top
A straight through cable (normal usage) requires the plugs at both ends of the cable to be wired in the same fashion while a cross-over cable (used to link one hub/switch to another) requires the reverse wiring of all pins on one end. Some switches/hubs can auto-sense which type of cable is used and automatically switch themselves into the required mode to support the cable used. The wiring scheme below is only ONE way to wire the plug but there are many other different ways that will also work.

David Prest uses the 2nd one above except that orange and orange/white are swapped for some reason.
