The present invention refers to a method (49) and a device (25, 31, 43) for monitoring the performance of a vectoring group (45) of telecommunication lines (13). In order to allow for either identifying or eliminating irregular events related to vectoring as a cause of transmission problems of a certain victim line (13) of a vectoring group (45), it is suggested that the method (49) comprise detecting (55, 59) depending on at least one first parameter (Gij, L) that characterizes crosstalk caused by a disturbing line (13) to a victim line (13) that the irregular event has occurred at an instant of time (t1, t2, t3, t4); deciding (57) on whether or not a transmission performance of the victim line (13) decreases within a time interval (”T), the time interval (”T) including the instant of time (t); and determining (63, 67) depending on the deciding (57) on whether or not the performance decrease is caused by the irregular event. |
