RJ45 SOCKET WIRING B
[SOLVED] RJ45 Type A + Type B? - Networking - Spiceworks
Feb 21, 2016Both ends of any ethernet cable need to be wired the SAME, or they will not work correctly.

Terminating Wall Plates / Wiring - Structured Home Wiring
There are two standards for wiring RJ45: TIA/EIA 568 A & TIA/EIA 568 B. The A standard provides backward compatibility with phone wires. The inner 4 wires are wired the same (orange stripe, blue, blue stripe, orange) for both phone and data. The B standard is more common, perhaps because it is not backwards compatible with phone wires.
