The invention refers to a method (45) and device (25, 31, 43) for evaluating the stability of communication over a telecommunication line (13). In order to allow for assessing the stability of the line (13) more accurately, it is suggested that the method (45) comprise ascertaining physical line data (47) characterizing a physical characteristic of each line (13) of a fist set of subscriber lines; collecting service quality information (49) describing a quality of a service provided over each line (13) of a second set of subscriber lines; associating (53) the service quality information (47) related to at least one particular line (13) with the physical line data related to the same particular line (13); and determining (63, 65) a decision criterion (˜ u , ˜ s , “ u , “ s ) from the physical line data (47) with associated service quality information (49), said decision criterion (˜ u , ˜ s , “ u , “ s ) being determined for deciding to which stability class (S, R, U) of a plurality of stability classes (S, R, U) the digital subscriber line (13) belongs. |
