The invention refers to a method (45) and device (43) for estimating an attainable bitrate of an electrical telecommunication line (13). In order to allow for estimating the attainable bitrate of lines to which no DSL modem (19) is connected more accurately, it is proposed that the method (45) comprise estimating (49) a direct transfer function (Hlog) of the telecommunication line (13); estimating a noise (Xtalk) coupled into the telecommunication line (13); calculating (65) a bitrate value (BR) characterizing the attainable bitrate from the transfer function (Hlog) and the noise (Xtalk); and determining (51) at least one unbalance characteristic (U, LCL) that describes an unbalance of the telecommunication line (13); wherein said estimating the noise (Xtalk) comprises determining (59) the noise (Xtalk) from the unbalance characteristic (U, LCL). |
