In a system for identifying subscriber lines, an end of a subscriber line is coupled to and terminated by a transceiver of interest. The other end of the subscriber line is coupled to a speaker. The transceiver is then selectively activated and deactivated causing it to transmit its normal frequency spectrum in a predefined pattern. The frequency spectrum includes frequencies audible to humans. Thus, the speaker produces sound capable of being heard by a human, and the sound exhibits periods of noise followed by periods of silence. Indeed, the periods of noise and silence are in a pattern according to the activation/deactivation pattern of the transceiver. Thus, a user can identify the subscriber line that is coupled to the transceiver by identifying which of the lines is coupled to the speaker when the speaker emits noise and silence according to the predefined pattern.

Systems and methods for identifying subscriber lines

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.

Digital subscriber line fault locating systems and methods

The present disclosure generally pertains to systems and methods for identifying subscriber lines coupled to transceivers of interest. In one exemplary embodiment, an end of a subscriber line is coupled to and terminated by a transceiver of interest. The other end of the subscriber line is coupled to a speaker. The transceiver is then selectively activated and deactivated causing it to transmit its normal frequency spectrum in a predefined pattern. The frequency spectrum includes frequencies audible to humans. Thus, the speaker produces sound capable of being heard by a human, and the sound exhibits periods of noise followed by periods of silence. Indeed, the periods of noise and silence are in a pattern according to the activation/deactivation pattern of the transceiver. Thus, a user can identify the subscriber line that is coupled to the transceiver by identifying which of the lines is coupled to the speaker when the speaker emits noise and silence according to the predefined pattern.
