Adaptively applying a target noise margin to a DSL loop for DSL data rate establishment
InactiveUS20050237940A1Increase target noise marginLarge data-rateError preventionTransmission systemsData rateNoise margin
Methods, systems, and computer program products adaptively apply a target noise margin to a DSL loop to establish a DSL data rate on the DSL loop. A method involves receiving performance data associated with a quantity of errors detected over a period of time on the DSL loop and adjusting the target noise margin for the DSL loop based on the performance data. The target noise margin is inversely associated with the DSL data rate that can be established and is adjusted in order to maximize the DSL data rate while minimizing the quantity of errors detected over the period of time. Thus, embodiments of the present invention allow a maximum data rate that can be sustained on a DSL loop without an excessive quantity of errors.
