ABSTRACT:
Apparatus and method for transmitting over non-adjacent multiple conducting pairs and aggregating powers from the conducting pairs to power remote electronic devices at an end station include, at a line termination (LT), a plurality of power transmitting circuits configured to transmit power over the multiple conducting pairs, and a microcontroller coupled to the plurality of power transmitting circuits and configured to receive a current sense signal from a power receiving circuit at the remote electronic device, and further include, at a network termination (NT), one or more current limiters coupled to multiple conducting pairs and operable to limit the power from the conducting pairs based on power demand information of the end station, and a load controller coupled to the one or more current limiters and configured to selectively activate the one or more current limiters based on a determination by the microcontroller that the end station is allowed to receive a full power demand, the determination being a function of a demand current profile of the end station.
