T568A CABLE WITH A MISWIRE AND UNRECOGNIZED CONTINUITY:

CableMaster200
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.
