<p>The present invention refers to a method (67) and device (25, 31, 43; 39) for identifying crosstalk from a disturbing telecommunication line (55) to a victim telecommunication line (13) of a communication network (11), the identifying depending on quiet line noise measurement data (QLN) related to the victim telecommunication line (13). In order to provide such a method (67) and device (25, 31, 43; 39) that allows for detecting abnormally high crosstalk caused by high bit rate telecommunication lines (55) running in parallel to a section (55) of the victim telecommunication line (13), it is suggested that the method (67) comprise estimating (73) a coupling length (L) depending on the quiet line noise measurement data (QLN); and detecting (83, 87) depending on the coupling length (L) and a physical length (Lreal) of the victim telecommunication line (13) that the crosstalk is caused by the disturbing telecommunication line (13) extending in parallel to a section (52) of the victim telecommunication line (13).</p> |
