Abstract
A method for detecting inductive elements in a communication line, including the processes of: inputting a detecting signal to an end of the communication line; sampling the time domain voltage vector of one end of the communication line; generating the amplitude-frequency characteristic curve of the differential input impedance of one end of the communication line according to the time domain voltage vector; determining the number of the inductive elements in the communication line according to the number of the apexes or zeros on the curve. The present invention also discloses a device for detecting inductive elements in a communication line. By the present invention, the automatic detections of the number of inductive elements such as load coils or phone splitters in the communication line are implemented with the exact detection and the high efficiency, thereby lowering the cost of detecting failures of communication line.
