Methods for determining the location of a defect in a wired transmission line and systems according to such methods

摘要

In one embodiment, the method for locating a defect in a wired transmission line, which extends between a first end and a second end, includes measuring a first modified noise signal at the first end by a first measuring unit, and making a first representation of the first modified noise signal. A second modified noise signal is measured at the second end by a second measuring unit, and a second representation of the second modified noise signal is made. The location of the defects are derived from the representations.

1. A method for locating a defect in a wired transmission line of a telecommunications network, said transmission line extending between a first end and a second end, and said defect allowing the ingress of an external noise signal into said transmission line, comprising:
measuring a first modified noise signal at said first end by a first measuring unit, the first modified noise signal being a first modification of the external noise signal; determining a first representation of said first modified noise signal; measuring a second modified noise signal at said second end by a second measuring unit, the second modified noise signal being a second modification of the external noise signal; determining a second representation of said second modified noise signal; and deriving the location of said defect from said representations.
