Abstract: A telephone line test system that may be used to compute line length of subscriber lines connected to a central office or other distribution point. When initially installed, the test system may automatically compute CO limits. The CO limits are computed from single-ended measurements on subscriber lines and represent electrical effects of the path between a test head and the distribution point. These CO limits are used to more accurately compute the length of lines connected to the distribution point using measurements made by the test system. Because the process uses single-ended measurements, it may be run in background mode during the initial installation of the test system or at any subsequent time it is desired to update the CO limits.
Abstract translation: 可用于计算连接到中心局或其他分发点的用户线的线路长度的电话线路测试系统。 最初安装时，测试系统可以自动计算CO限制。 CO限制是从用户线上的单端测量计算出来的，并且表示测试头与分配点之间路径的电气效应。 这些CO限制用于使用测试系统进行的测量来更准确地计算连接到分配点的线路的长度。 由于该过程使用单端测量，因此可能会在初始安装测试系统时或后续时间更新CO限制时在后台运行。

Abstract: A system for identifying service affecting conditions on a subscriber line in the access portion of a broadband network, particularly an ADSL network. A measurement unit provides information on the line that aids in identifying projected performance. Information from a modem on the subscriber line indicative of actual performance is obtained and compared to the predicted values. Deviations are used to identify service affecting conditions and, depending on the nature of the deviations, the type of condition affecting service on the line. The physical measurements are used to identify the length of the subscriber line. Modem information is obtained through the MIB and allows determination of the bit loading on the line. Interference sources are identified by comparing the actual bit loading to bit loading expected for a line corresponding to the measured length.
