Abstract (en)
[origin: WO9844428A1] A telecommunications fault location and diagnostic system employs a remote test unit (RTU) (2) to collect system parameter data. The RTU is operatively coupled to a trained neural network (30) which receives the system parameter data from the RTU (2). The neural network (3) is trained using pre-screened historical fault data which is stored in a database. Once trained the neural network classifies the RTU data into one of a predetermined number of fault probabilities.
