Abstract

A system in accordance with an exemplary embodiment of the present disclosure comprises an NAD positioned at an intermediate point between a network facility and one or more customer premises (CP). The NAD is coupled to CP transceivers located at the one or more customer premises via a plurality of subscriber lines. The CP transceivers are configured to provide power to and also communicate with the NAD via the subscriber lines. The NAD is further configured to form a power signal based on the power received from multiple subscriber lines and to provide the power signal to components of the NAD. The NAD is further configured to determine from which of the subscriber lines it is receiving at least a certain amount of power and to selectively enable and disable the communication service provided over each respective subscriber line based on such determination. The NAD also powers down at least some components of the NAD that were used to previously provide the services that have since been disabled.
