Method and device for locating an impairment within a telecommunication line

摘要

A method for locating an impairment within a telecommunication line may include determining measurement data related to the telecommunication line and estimating a location of the impairment depending on the measurement data. The measurement data includes crosstalk data including at least one transfer function element of a crosstalk matrix. The transfer function element characterizes a crosstalk transfer function from the telecommunication line towards the at least one further telecommunication line, and the method includes detecting oscillations in the crosstalk transfer function.

1. A method for locating an impairment within a telecommunication line, the method comprising:
determining measurement data, the measurement data including,
a crosstalk matrix having crosstalk transfer coefficients, the crosstalk transfer coefficients representing the crosstalk between the telecommunication line and at least one further telecommunication line within a same binder, diagonal elements of the crosstalk matrix each having a value of zero, anda direct transfer function data; and determining a location of the impairment within the telecommunication line by,
determining a plurality of possible locations of the impairment based on the direct transfer function data,determining a ratio between an amplitude of each of a plurality of oscillations in the crosstalk transfer coefficients and an amplitude of each of a plurality of the oscillations in the direct transfer function data, andselecting one of said plurality of possible locations that is closest to a signal source as the location of the impairment if a correspondingly determined ratio is greater than or equal to a threshold.
