Abstract
A method to identify impairments in telecommunication lines i, j , k, . . . of a binder includes globally performing Single-Ended Line Testing SELT on the lines of the bundle. The method further includes applying an input signal in a first mode out of a multi-mode group including at least one differential mode for a respective line of the bundle and including at least one phantom mode for a respective pair of lines of the bundle. The method further includes measuring an echo signal E in a second mode out of the multi-mode group, the second mode being different of the first mode, and analyzing the echo signal in view of the input signal for deriving therefrom the searched impairments.
