Abstract
Systems and methods of a field deployed access CPE device with smart and efficient agent integrated with an agile software architecture to collect and analyze proactive network maintenance (PNM) management information base (MIB) data. The access CPE device may determine the OFDMA channel's impulse response and group delay, stream the collected data to the operator's streaming and analytics platform to identify cable plant faults, determine whether the identified faults are located inside or outside the customer's home, and mitigate the impact of the identified faults via machine learning models.

A method for detecting and analyzing cable plant impairments, comprising:
- collecting, by a component with a data collector in a field deployed device, proactive network maintenance (PNM) management information base (MIB) data;
- parsing the collected PNM MIB data for all active subcarriers of an orthogonal frequency division multiple access (OFDMA) channel;
- removing a phase rotation from the parsed PNM MIB data at a cable modem termination system (CMTS);
- performing an inverse Fourier transform on the parsed PNM MIB data to generate a transform result;
- determining an impulse response value and a group delay value based on the generated transform result;
- and
- sending the determined impulse response value and the determined group delay value to a machine learning model in a streaming and analytics platform in a service provider network.
