Communications channel impairment detection system

A method, comprising:

• sampling, at a first device, data signals communicated with the first device via one or more channels on a network;
• determining attributes comprising a signal envelope and a noise floor of the one or more channels at the first device based on a first set of data signal samples;
• normalizing a second set of data signal samples based on the determined attributes of the one or more channels;
• processing the normalized second set of data signal samples at the first device using a machine learning model to generate an indication of impairment in the one or more channels;
• determining, based on the indication, one or more characteristics of the impairment in the one or more channels;
• and
• generating and transmitting a notification comprising the determined one or more characteristics of the impairment to a second device via the one or more channels on the network.

An electronic device, comprising:

• a network interface configured to receive data signals via one or more downstream channels on a network and to transmit data signals via one or more upstream channels on the network;
• a machine learning processing engine configured to execute an autoencoder neural network model;
• computer-readable storage media storing one or more sequences of instructions;
• and
• processing circuitry configured to execute the one or more sequences of instructions to perform operations comprising:
• sampling the data signals communicated via the network interface;
• determining attributes comprising a signal envelope and a noise floor of the one or more channels based on a first set of data signal samples;
• normalizing a second set of data signal samples based on the determined attributes of the one or more channels;
• providing the normalized second set of data signal samples to the machine learning processing engine and receiving an indication of impairment in the one or more channels from the machine learning processing engine;
• determining, based on the indication, one or more characteristics of the impairment in the one or more channels;
• and
• generating and transmitting a notification comprising the determined one or more characteristics of the impairment to a controller via the network interface.
