The patent filed by BT Group Plc describes a method for determining the location of a disconnection on a digital subscriber line, specifically a VDSL line, by generating a statistical model based on line test measurements and inventory data. The model maps measured loop lengths to predicted loop lengths and uses knowledge of node positions to calculate the probability of a disconnection occurring at a specific node. The method involves interpreting line test measurements, applying regression analysis to calculate a function mapping loop lengths, and determining the location of a disconnect by comparing predicted loop lengths to node positions.
Additionally, the patent includes a test module designed to implement the method described, which involves determining measured loop lengths, calculating a mapping function, determining node positions, and ultimately identifying the location of a disconnection on the test digital subscriber line. The method also includes calculating residuals between the function and loop length measurements, determining a distribution of residuals, and using this information to calculate the probability of a disconnection at each node on the line. Overall, the patent outlines a systematic approach to pinpointing disconnections on digital subscriber lines by leveraging statistical modeling and line test data.
