Abstract

An apparatus for use in a cable system comprises a first port for use in coupling to a portion of a cable network for receiving an upstream signal having a frequency spectrum including a first frequency band; and a remodulator for translating the first frequency band of the received upstream signal to a second frequency band for transmission back downstream via the first port; wherein the first frequency band and the second frequency band are different from those frequency bands used by a head-end of the cable network for Internet communications.
