Abstract: A device for testing pairs of wires in a cable which includes a testing console having known means for performing tests on the wires and having a test fixture with a plurality of pins extending through a mating surface, the pins being arranged and arrayed to enter holes containing wires to by tested in a terminal fixture, the terminal fixture having holes into which wires may be inserted and held by friction, the holes opening in a terminal fixture having the holes in the same array as the array of pins in the test fixture so that when the terminal fixture and the test fixture are brought together with the same orientation the pins extending from the test fixture enter the holes in the terminal fixture and make a circuit between the testing console and the wire, and the console includes a rotating switch arrangement to bring both ends of each wire into circuit with testing equipment consecutively and one-at-a-time.

Abstract: A system for measuring the capacitance of an electric signal conductor, with particular interest on telephone cables. A waveform generator produces a test signal which is coupled to the conductor. The resultant signal emerging from the conductor is delivered to a receiver, and then to an integrator, to produce an output signal which is a direct digital measure of the conductor's capacitance.

Abstract: An auxiliary test system for use with a long transmission line such as one having a telephone at an end thereof whereby from a remote central test station a line may be tested for a short between wires, an open, an abnormal load condition or reversed connections and the relative location of such a fault condition determined.
