Abstract
A method and system for provisioning remote user data access over digital subscriber lines (DSL's) through connection-oriented packet networks is described. According to a preferred embodiment, DSL terminal units are directed to train at a rate that is not substantially greater than the subscribed data rate, thereby avoiding network congestion due to data rate mismatches between the DSL connection and a corresponding permanent virtual circuit (PVC) channel through the connection-oriented packet network. According to another preferred embodiment, the DSL units are directed to test for the maximum trainable data rate before settling to the subscribed data rate, and to communicate this information to a network operations center computer, thereby allowing the maximum allowable DSL data rate to be compared to actual client traffic usage patterns and to the client's subscribed data rate. According to another preferred embodiment, in the event that the maximum trainable rate lies substantially below the subscribed data rate, the network operations center automatically re-provisions the permanent virtual circuit (PVC) channel through the connection-oriented packet network to a corresponding lower level, thereby conserving network resources.
