Hybrid fibre coaxial fault classification in cable network environments
One embodiment is a system including a data collector located in a cable network for capturing multi-tone signals traversing the cable network; a data repository located in a cloud network and having an interface for communicating with the data collector and for storing the multi-tone signals captured by the data collector and network data associated with the cable network; and a central server including a memory element storing Predictive Services Management (PSM) algorithms comprising instructions and associated data and a processor operable to execute the PSM algorithms. The central server is configured for detecting a fault in the cable network and identifying a segment associated with the fault; determining a maximum tap magnitude for the fault; calculating an aggregate tap magnitude for the fault; and classifying a severity of the fault based at least in part on the maximum tap magnitude and the aggregate tap magnitude.
