Cable network gateway with digital docsis/moca bridge

A method for servicing cable communications comprising:

• receiving a downstream broadband signal via service provider cabling;
• converting the downstream broadband signal to a digital downstream broadband signal;
• low pass filtering the digital downstream broadband signal to attenuate an upper portion of a spectrum of the digital downstream broadband signal to produce a filtered digitized downstream broadband signal;
• receiving a first signal from a local network interface at an in-home communications transceiver;
• producing a digital in-home communications signal from the first signal, the digital in-home communications signal overlapping the upper portion of the spectrum;
• summing the filtered digitized downstream broadband signal with the digital in-home communications signal to produce a combined digital signal;
• converting the combined digital signal to a combined analog signal;
• and
• transmitting the combined analog signal via in-home cabling.

A cable network gateway integrated circuit comprising:

• an Analog to Digital Converter (ADC) configured to receive a downstream broadband signal and to convert the downstream broadband signal to a digital downstream broadband signal;
• a digital filter configured to attenuate an upper portion of a spectrum of the digital downstream broadband signal to produce a filtered digitized downstream broadband signal;
• an in-home communications transceiver configured to produce a digital in-home communications signal that overlaps the upper portion of the spectrum;
• summing circuitry configured to sum 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) configured to convert the combined digital signal to a combined analog signal and to transmit the combined analog signal. and a transmit path coupling the digital in-home communications signal to the in-home cable interface, wherein the transmit path bypasses the summing circuitry.
