Abstract
Abstract This specification discloses an improvement in method and apparatus for identifying at a remote position conductors in a multiconductor means having the conductors identified at one end. The improvement is characterized by sequentially stepping by control signals from the remote position a sequential stepping switch onto contacts to which the identified conductors at the one end are connected, until a specifically identified conductor is connected with the sequential stepping switch. Thereafter, an identifiable signal is put on the specifically identified conductor and the conductor carrying the signal at the remote position is identified. The invention is particularly described with respect to repairing a telephone cable, or reconnecting groups of wire pairs from one cable to another in a telephone line system. In such telephonic work, ordinarily, it is advantageous to employ a second sequential switching device in conjunction with the sequential stepping switch to be able to monitor a pair of conductors, or wires, and to thereafter check out each individual wire of the pair. Also, disclosed is a field monitor unit to assist the repairman in maintaining a record of the particular conductor onto which the sequential stepping switch has been actuated. Other aspects are also described; such as, a flip-flop mode of operation in which correlated pairs of wires in a multiwire cable are identified for immediate changing of wires in a group with consequent lessening of chance of error.
