    摘要： A method for determining performance of data communication lines in a DSL network is provided. The method includes determining a performance metric for at least one line from a first set of data that included measurements for each of a plurality of parameters related to the at least one line; establishing a benchmark utilizing a second set of measurements that includes at least one additional measurement for the plurality of parameters; and comparing the performance metric with the benchmark to determine the performance of the at least one line.

    摘要： The application discloses a system and a method of selecting a profile of a digital subscriber line. In a particular embodiment, the method includes setting a threshold for voice quality and determining a number of acceptable code violations that can occur without compromising the voice quality of the digital subscriber line. When the actual number of code violations exceeds the determined number of code violations an alternate profile is selected for the DSL line.

    摘要： A system and method is described for determining a condition of a communication line, such as the absence of a filter device on a digital subscriber line (DSL). A first signal characterized by a high upstream power is activated over the line, and a first set of parameters associated with the communication line is obtained. A second signal characterized by a low upstream power is activated, and a second set of parameters associated with the communication line is obtained. Comparison of first and second sets of parameters is indicative of a condition of the connection and presences or absence of a DSL filter on the communication line.

    摘要： In a particular embodiment a method of collecting and processing modem data is provided. The method includes, during training of a broadband modem, sending a series of tones within a frequency transmission band of the broadband modem, receiving the transmitted series of tones at a receiving broadband modem, receiving a measurement value, determining a transmission loss for each of the series of tones by comparing the predetermined transmission power level, and the received measured power level, performing a statistical match comparison between each of the received tone signals and a plurality of different computer models of a single transmission facility having various bridge taps connected to the single transmission facility, and determining a best fit between each of the received tone signals and one of the plurality of the bridge tap computer models. The series of tones have a predetermined transmission power level.
