Specifications

Properly Wired T568A UTP:
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.
Properly Wired T568A UTP:
T568A Cable with Split Pairs:
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.

T568A Cable with a Short and an Open:
The 1-2 pair pins are shorted together and the 7-8 pair is open.
The pins with the errors are flashing. Dash lines (-) on the bottom
(remote) display line indicate the short, while no numbers on the
bottom line indicate the open pair.

Short and Open:
T568A Cable with a Miswire and unrecognized Continuity:
1 and 2 pins on the VDV MapMaster2.0™ are connected to pins
2 and 1 at the remote-end. The pins with this error are flashing.
The “U” for the remote pin numbers indicates an unrecognizable
continuity was detected that is neither a short or open. An ID
remote connected to the VDV MapMaster2.0™ when in cable
test mode would also show this error.
