1. A method comprising:

  • accessing, by a computing device, a plurality of frequency characteristics of signals on a network, the plurality of frequency characteristics corresponding to the signals at a respective plurality of access devices connected to the network;

    comparing the plurality of frequency characteristics to a plurality of different pre-characterized fault types;

    determining that a particular type of fault exists in the network based on the comparing;

    selecting, based on the particular type of fault, a fault detection algorithm from a plurality of fault detection algorithms; and

    determining a location of the particular type of fault in the network based on the fault detection algorithm and a shape of the plurality of frequency characteristics across a frequency range.
