1. A method for reducing aggregated ingress noise in a shared fiber-coax network that carries information from a head end to a plurality of subscribers via at least one main coax trunk and for carrying information originated by said plurality of subscribers to said head end via said main coax trunk using a repeater, the method comprising the steps of:

  • aggregating onto the main coax information generated by said plurality of subscribers;

    digitizing the aggregated subscriber-originated information; and

    digitally regenerating the digitized aggregated subscriber-originated information to reduce the incidence of noise in the aggregated subscriber-originated information on the main coax.
