Which Wiring Schemes?

Ethernet cables have several standard wiring schemes. T568A and T568B are the common wiring schemes which define the order of the individual wires and pin-outs for eight-pin modular connectors and jacks. If the cable is used for home-networking connections, T568B wiring scheme is recommended. T568A wiring scheme may be employed for the preexisting residential network wiring or other similar projects. The following figure presents the different wiring orders of T568A and T568B.
