WIRING AND DISPLAY EXAMPLES

T568B is electrically identical to

T568A, but swaps the green and

orange pairs. Either standard will

work as long as the same standard

is used at both ends of a run or

patch cable. Mixing “A” and “B”

creates a cross-over cable.

A common error in building a cable

is to put all the pairs in pin sequence

1-2, 3-4, 5-6 and 7-8. This will

produce the correct continuity, but

the pairs are designated to be on

pins 3-6 and 4-5 in the middle of

the connector for compatibility with

phone wiring. This wiring error is

only detected by the split pair test

since the designated pairs are not

twisted together.
