The present invention refers to a method (65) and device (17, 19, 39) for detecting a bridged tap (45, 53) within a telecommunication line (13). In order to reliably detect bridged taps of different types, in particular wire pair bridged taps and single wire bridged taps, and/or to determine a type (T) of each detected bridged tap it is suggested that the method comprise determining (73) first transfer function data (Hlog) that characterize an actual transfer function (57) of the telecommunication line; detecting (69) the bridged tap (45, 53) depending on the first transfer function data (Hlog); simulating (97) the telecommunication line (13) based on a result (Lt, L, k) of said detecting; and identifying (99) the type (T) of the bridged tap (45, 53) by comparing results (SHlog1, SHlog2) of said simulating with the first transfer function data (Hlog). |
