Patent ID: 7809116

Claim:
A method of estimating the configuration of an unknown DSL loop, the method comprising: (1) providing a database comprising loop configuration information and known loop operational data for one or more known DSL loop configurations, wherein providing the database further comprises: sending data on a known DSL loop having a known loop configuration using a plurality of line profiles, wherein for each of the plurality of line profiles data is sent between a transceiver pair comprising an active DSL modem at each end of the known loop; and collecting the known loop operational data resulting from the data sent on the known DSL loop having the known configuration; (2) collecting unknown loop operational data from the unknown DSL loop using one or more known line profiles, wherein the unknown loop operational data is a result of transmissions between a transceiver pair, the transceiver pair comprising an active DSL modem at each end of the unknown DSL loop; (3) estimating the configuration of the unknown DSL loop by comparing the collected unknown loop operational data to the known loop operational data in the database.
