ABSTRACT:
Method and apparatus are provided for detecting the existence of physical faults such as shorts, grounds, opens, crosses, splits and punchbacks in a multiconductor cable composed of paired conductors. Such paired conductor cables are typically used in telephone transmission networks. Each of the conductors within the cable exhibit a distributed capacitance with respect to a metallic cable sheath and with respect to all of the other conductors. The various cable faults mentioned above are quickly and effectively detected by selectively conducting each pair of conductors to a test circuit. The test circuit periodically electrically charges and discharges each of the lines and in so doing provides a measurement of the distributed capacitance of each pair which may be compared with corresponding capacitance measurements obtained from the other pairs of conductors of the same cable. The comparative measurement quickly reveals any faults in the various conductors.
