Abstract

A method and apparatus for single end loop testing for DSL provisioning and maintenance provides testing of the DSL loop using digital techniques including frequency compensation, matched filtering and median filtering, to remove strong background and enhance desired signal for peak detection. The SELT system allows DSL providers to extract loop information from reflective measurements at the central office (CO) so as to determine loop capability of supporting different DSL services. The method and apparatus acquires the desired signal (the far-end echo) which is submerged in the correlated background noise (the near-end echo) by providing a process for detecting loop length and termination types with high accuracy for loops up to 12 kft for 24 AWG and up to 9 kft for 26 AWG by exploiting several digital signal processing techniques including frequency.

Description

[0001] Cross References to Related Applications [0002] [0001] This application claims priority to co-pending U.S. Provisional Patent Application No. 60 / 536,255, filed January 14, 2004, entitled "System and Method For Single End Loop Testing For DSL Provisioning and Maintenance," which The entire contents are hereby incorporated by reference. technical field [0003] [0002] The present invention relates generally to electronic communication systems, and more particularly to methods and systems for extracting delivery context (ie, "loop or loop") information, such as loop length and loop termination, for use in providing and maintaining digital subscriber Line (DSL) loop. Background technique [0004] [0003] Today's popular high bandwidth technologies use existing copper wire infrastructure deployed by Plain Old Telephone System (POTS) communications. With the advent of the Internet and other high-bandwidth electronic communication networks and systems and the growing cons...
