<p>A splitter-detecting method, device and system are provided. The method includes the following steps of establishing an integrated service digital network (ISDN) disturber power spectrum density (PSD) model; acquiring bit distributing parameters of digital subscriber line (xDSL) sub-carriers, and detecting whether an xDSL/ISDN splitter is absent according to the correlation between the ISDN disturber PSD model and the bit distributing parameters of the xDSL sub-carriers; or acquiring a quiet line noise (QLN) of the xDSL line, and detecting whether the xDSL/ISDN splitter is absent according to the similarity between the ISDN disturber PSD model and the QLN of the xDSL line. In the embodiments of the present invention, the fault of the xDSL/ISDN splitter being absent can be automatically detected by the parameters acquired by a network management system, thereby reducing the cost of maintenance.</p> |
