Abstract
A cable network gateway receives a downstream broadband signal via service provider cabling at an interface. An Analog to Digital Converter (ADC) converts the downstream broadband signal to a digital downstream broadband signal. A digital filter attenuates an upper spectrum from the digital downstream broadband signal to produce a filtered digitized downstream broadband signal. An in-home communications transceiver produces a digital in-home communications signal that overlaps the upper spectrum. Summing circuitry sums the filtered digitized downstream broadband signal with the digital in-home communications signal to produce a combined digital signal. A Digital to Analog Converter (DAC) converts the combined digital signal to a combined analog signal and an in-home cable interface transmits the combined analog signal via in-home cabling. The downstream broadband signal may be a Data over Cable System Interface Specification (DOCSIS) 3.0/3.1 signal and the digital in-home communications signal comprises a Multimedia over Coaxial Alliance (MoCA) signal.
