Abstract
Systems and methods for locating faults in a digital subscriber line (DSL) system in accordance with the disclosure include a handshake messaging procedure that is used to rapidly obtain interconnectivity information of various subscriber loops that are present in a DSL repeater chain. The interconnectivity information is used to provide an identification of one or more faulty loops when such faulty loops are present in the DSL repeater chain. The identification may be provided in the form of a topological representation that can be used to execute targeted line testing procedures on the faulty loops without wasting time on testing loops that are not faulty.
