Abstract:
A method of identifying the location and amplitude of a source of noise along a wireline telecommunication link comprising the steps of:(a) conducting electrical measurements from a single access location in a telecommunication facility to said wireline telecommunication link, that include measuring noise on said wireline telecommunication link at each cross-connect point of a switch, and a measurement from which attenuation along and length of said wireline telecommunication link may be determined; and (b) processing measurement values obtained in step (a) to determine the location of said source of noise and the amplitude of the noise at said location of said wireline telecommunication link by storing measured noise values associated with each cross-connect point of a switch, averaging noise values for any unterminated cross points to derive a noise balance representative of noise attributable to a central office, determining wireline length and loss per unit length based on capacitance measurements, determining a noise difference value that is attributable only to a noise source at a cable drop source and determining the noise amplitude and its location from the wire length, loss per unit length and noise difference values.
