1. A cable testing apparatus for testing the wires of a multi-wire cable for opens, said apparatus comprising:

  • input means adapted to be connected to a multi-wire cable to enable testing for opens in wires of said cable that has been directly electrically connected at one end to form wire pairs, said input means including signal routing means connectable with the other end of said wires of said cables for maintaining different pairs of wires of said cable so connected electrically separated from one another and for producing a distinguishable indication whenever a said pair of wires of said cable is sensed to be open;

    indicating means connected with said signal routing means to receive said distinguishable indication of an open therefrom, said indicating means including digital display means; and

    control means connected with said indicating means and said signal routing means for causing automatic sequential monitoring of said pairs of wires of said cable when so connected to said input means and for causing interruption of said sequential monitoring with said display means being caused to produce a discernable digital indication of an open then sensed at said input means.
