Abstract
A method and computer program product for detecting faults in cables. The invention comprises receiving a first reflected signal; comparing the first reflected signal amplified with a first predetermined receiver gain setting with a first threshold; if the value of the amplified first reflected signal is greater than the value of the first threshold, then terminating detecting; if the value of the amplified first reflected signal is not greater than the value of the first threshold, then comparing a second reflected signal amplified with a second predetermined gain setting different from the first gain setting with a second threshold.
