ABSTRACT:
A cable analyzer is capable of having at least 3 pairs of wire from telephone cables connected to the analyzer. By a central processing unit or computer in the analyzer, a series of relays connect any one of the pair of wires to a routing board. At the routing board, a plurality of analog tests may be directed to be conducted upon the pair of wires and ground, or the wires may be routed within the analyzer for other purposes. The results of the analog tests are converted to binary digital format so that they may be analyzed by the central processing unit. The results are visually displayed. The central processing unit has the capabilities, through different programs, to cause the analyzer to conduct a plurality of procedures upon each pair and to connect the pairs. Two analyzers, physically separated, are connected as master and slave so that the master analyzer controls the slave analyzer. One important procedure possible by the master/slave connection is the transfer of a communications circuit from an old section of a pair of wires in an old cable to a new section of a pair of wires in a new cable in less than 1 millisecond.
