What’s the difference between T568A and T568B wiring schemes?
T568A and T568B are the standards specified by ANSI, TIA and EIA for RJ45 jacks and plugs that refers to the position of the wires inside the eight-position modular plugs. These two standards are very alike. The only visible difference between them is that pairs 2 and 3 (green and orange) are interchanged.
