Method and device for determining a length value of a section of a telecommunication line

摘要

The present invention refers to a method (71) and device (25, 43, 47) for determining a length value (L ES , DPBOESEL) characterizing a length (L ES ) of a first section (50) of a first telecommunication line (13), a second section (52) of the first telecommunication line (13) being arranged along at least one second telecommunication line (55) so that the first telecommunication line (13) causes crosstalk (60) to the second telecommunication line (55). In order to allow for automatically determine the length value (L ES ), it is suggested that the method (71) comprise acquiring (83) line noise measurement data (QLN) characterizing quiet line noise of the second telecommunication line (55); and determining (85) the length value (L ES ) depending on the line noise measurement data (QLN).
