1. An apparatus for characterizing the loading pattern of a telecommunications transmission line comprising:

  • a signal generator producing a variable frequency output signal coupled to the telecommunications transmission line;

    a measurement receiver coupled to the telecommunications transmission line that acquires magnitude values representative of the impedance of the telecommunications transmission line as a function of the signal generator output frequency;

    means for modeling a plurality of telecommunications transmission lines to generate magnitude values representative of the impedance of the modeled telecommunications transmission lines as a function of frequency;

    means for calculating an error value for each of the modeled telecommunications transmission lines by comparing the acquired magnitude values with the modeled magnitude values; and

    means for comparing the error values of the modeled telecommunications transmission lines to each other to determine the modeled telecommunications transmission line with the minimum error value that characterizes the loading pattern of the measured telecommunications transmission line.
