摘要： The present invention provides a method and apparatus for improving the performance of splitterless ADSL systems. The present invention provides a uniform technique for adapting an ADSL system to any of these situations. The invention provides a graduated approach to handling anomalies that may be caused by incompatible telephone equipment. One embodiment of the invention attempts to correct anomalous situations without having to interrupt the data communication. If more information is needed, a very brief channel echo measurement is conducted. Only if the problem cannot be resolved at this point is retraining of the modem performed. This approach greatly minimizes interruption of data communication and reduction of bandwidth. Another embodiment of the invention reduces the transmitted signal level to its lowest practical value to minimize interference with telephone equipment. Multiple levels of signal reduction are available, and user input may be obtained to optimize the transmit signal level.
