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 toAnalog 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.

Abstract: A communication device (e.g., a cable modem (CM)) includes a digital to analog converter (DAC) and a power amplifier (PA) that generate a signal to be transmitting via a communication interface to another communication device (e.g., cable modem termination system (CMTS)). The CM includes diagnostic analyzer that samples the signal based on a fullband sample capture corresponding to a full bandwidth and/or a subset (e.g., narrowband) sample capture to generate a fullband and/or subset signal capture (e.g., of an upstream (US) communication channel between the CM and the CMTS). The diagnostic analyzer can be configured to generate sample captures of the signal based on any desired parameter(s), condition(s), and/or trigger(s). The CM then transmits the signal to the CMTS and the fullband and/or subset signal capture to the CMTS and/or a proactive network maintenance (PNM) communication device to determine at least one characteristic associated with performance of the US communication channel.
