    Abstract: 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), wherein the method (71) comprises selecting (75) a transmit power signal density of at least one third data signal transmitted over a third telecommunication line (56) arranged along the second telecommunication line (55) such that the crosstalk caused by the first telecommunication line (13) dominates the crosstalk caused by a third telecommunication line (56).

    Abstract translation: 本发明涉及用于确定表征第一电信线路(13)的第一部分(50)的长度(LES)的长度值(LES,DPBOESEL)的方法(71)和装置(25,43,47) ,所述第一电信线路(13)的第二部分(52)沿着至少一个第二电信线路(55)布置,使得所述第一电信线路(13)对所述第二电信线路(55)引起串扰(60)。 为了允许自动确定长度值(LES),建议方法(71)包括获取(83)表征第二电信线路(55)的静噪线路噪声的线路噪声测量数据(QLN); 以及根据所述线路噪声测量数据(QLN)确定(85)所述长度值(LES),其中所述方法(71)包括选择(75)通过第三电信传输的至少一个第三数据信号的发射功率信号密度 线路(56)沿着第二电信线路(55)布置,使得由第一电信线路(13)引起的串扰支配由第三电信线路(56)引起的串扰。
