<p>In order to identify a line (d1, d2, d3) holding a disturbing power supply unit for a plurality of Digital Subscriber Lines (d1, v11, v12, v13, v14, v15, d2, v21, v22, v23, d3, v31, v32, v33, v34, ...), noise data as a function of frequency (221, 222, 223, 224, 225, 226; 311, 312, 313, ... 31 M) are collected. In the noise data, the presence or absence of one or more noise signature of one or more disturbing power supply unit, is detected. Next, lines that are impacted by a noise signature from a common disturbing power supply unit are grouped into one or more groups of common victim lines (G1, G2, G3). Within each group (G1, G2, G3) a disturbing line (d1, d2, d3) holding the common disturbing power supply unit is identified as the line with most severe noise signature from the common disturbing power supply unit.</p> |
