## Abstract

A plurality of digital communication ports, such as a plurality of modems, for communications with a distribution point unit (DPU) over multiple conductors, the modems including communication electronics for communicating radio frequency modulation (RF) communications over the multiple conductors and power electronics configured to programmably provide power to the DPU over at least some of the multiple conductors. The modems further including machine executable instructions for providing shared reverse power feed for the DPU. A variety of computing approaches may be used to generate the instructions for shared reverse powering of the DPU and other components of the system.
