ABSTRACT:
A method for supplying power to a local area network node over communication cabling, the method comprising: injecting current-limited current into communication cabling connected to the local area network node; measuring a voltage developed in accordance with said injected current limited current across said communication cabling at three pre-determined intervals; and determining, as a consequence of said measured voltage at said three pre-determined intervals whether characteristics of the local area network node allow it to receive power over the communication cabling.
