ABSTRACT:
A cable analyzer is capable of having a group of 25 pairs of wire from a telephone cable connected by a module 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 or printed. The central processing unit has the capabilities, through different programs, to conduct a plurality of tests upon each pair, and upon the completion of the plurality of tests, proceed to a subsequent pair for a plurality of tests. Furthermore, the central processing unit has means whereby the results of tests may be transmitted on standard RS232C; or the analyzer may be controlled from a remote location by RS232C transmission to the analyzer.
