Abstract
Apparatus and methods of remote powering of DSL ADMs are disclosed. In a subscriber communication node, at least communication components that enable the subscriber communication node to communicate with a network switching device, and possibly also subscriber communication components that enable one or more subscriber communication devices to communicate with the network switching device, can be powered either by a local power source or remotely through an electrically conductive twisted wire pair. A network node may derive its own power and also supply power to subscriber communication nodes through twisted wire pairs. A linear or ring topology of subscriber communication nodes can thus be kept operational, and subscriber communications can potentially also be maintained, when a local power source at one or more subscriber nodes becomes unavailable.
