    摘要: The present invention relates to a method by which an xDSL modem can be properly connected and/or optimally tuned to achieve a desired performance goal based on knowledge obtained by first performing a SELT test and then post-processing the results of that test. In embodiments, the processed SELT results are used to detect bad connections or other anomalies such as split pairs. In embodiments, the processed SELT results are used to configure programmable components and filters in the analog front end in a manner that achieves the performance goal. In these and other embodiments, the performance goal is to maximize the attainable data rate. As such, through various hardware design options and configurations according to the invention, the performance of the modem can be tuned such that even in the presence of undesirable loop characteristics, adequate, or even good performance, can be achieved.

    摘要: According to certain aspects, the present invention relates to methods and apparatuses to identify and locate a line-cuts in a loop that may or may not also contain bridgetaps. In embodiments, different bands of SELT signal data are analyzed separately using a TDR method, to effectively detect any potential bridgetaps. In these and other embodiments, by combining information from the separate bands, bridgetap locations and lengths are determined. Methodology is also established to distinguish legitimate line cut or bridgetap signal data from spurious data. According to certain aspects, embodiments of the invention also incorporate baselining, which includes tests to make sure that there are no inconsistencies or imperfections that can corrupt the SELT data.

    摘要: The present invention provides a method of testing a transmission line from a copper access network. The transmission line is tested to generate values for a plurality of network parameters. Using previously determined test results, it is possible to calculate an estimate of the length of the transmission line based on the values of each of the measured parameters. These estimates of the transmission line length can then be used to compute a weighted average of the transmission line length. An inference of the condition of the transmission line can be made by comparing the estimates of the length of the transmission line with the weighted average length.

    摘要: In switching centers serving multiple local access providers, a problem arises in detecting cable failure and identifying the provider of the failed cable connected between the switching center and remote terminals. A test circuit installed in each cable port of the switching center detects failed cables; identifies the operator of the failed cable, and designates the cable end at which the failure occurs. The test circuit includes a signal detector and a signal generator and monitor connected through a switching device to the cables. A data signal Ds is transmitted on the cables. When the detector recognizes a loss of a data signal Ds exceeding a threshold a failed cable has occurred at one end of the cable or the other. The switch is activated by the signal loss to connect the signal generator and monitor to determine at which cable end the cable has failed. A reference signal Rs is injected into a cable by the signal generator and monitor. If the data signal Ds on the failed cable matches the reference signal Rs in amplitude and phase, a cable failure is indicated at the near end of the cable detector. If the data signal Ds is degraded in amplitude and shifted in phase relative to the reference signal Rs, a cable failure is indicated at the far end of the cable.

    摘要: A method and connectivity evaluation system for testing trunk lines dedicated by a centralized telecommunications system to a customer switching system, such as a PBX, includes allowing the trunk-seizing capability of the telecommunications system to be remotely accessed from the premises of the customer switching system. The dedicated trunk lines can be sequentially isolated in response to the remote access of the trunk-seizing capability. Isolated trunk lines can be used to transmit test signals to opposite end equipment for evaluating characteristics of the signal. The test signals can be generated from either or both of the central office of the telecommunications system and the premises of the customer switching system, but in the preferred embodiment, all such transmissions are controlled from the customer switching system. In another embodiment, the transmissions are controlled from the central office.
