Systems and methods for performing dsl loop qualification

摘要

A system predicts digital subscriber line (DSL) performance on an existing telephone loop. The system obtains a topological description of the existing telephone loop ( 410 ) and identifies a loop equivalent to the existing telephone loop from the topological description of the existing telephone loop ( 440 ). The system then determines DSL performance for the equivalent loop ( 450 ). From the DSL performance for the equivalent loop, the system predicts DSL performance for the existing telephone loop ( 460 ).
