Automatic configuration updating to stabilize ports in a telecommunication system

Abstract:

Multiple ports of a vectored digital subscriber line (DSL) system can be automatically reconfigured to respond to a fault or defect associated with another one of the ports of the system. Information regarding retrain events for the ports of the system can be examined to identify the "bad" port with the associated fault or defect and the corresponding group of ports affected by the bad port. The affected group of ports can be identified as a group of ports that all were retrained within a predetermined time period and for common retrain reasons (e.g., 1 or 2 different retrain reasons). Once the affected group of ports is identified, the affected group of ports and the bad port can receive corresponding repair profiles to reconfigure the ports to respond to the fault or defect.
