| 1. A computer-implemented method for adaptively applying a target noise margin to a digital subscriber line (DSL) loop to
establish a DSL data rate on the DSL loop, the method comprising:
receiving, by a processor, performance data associated with a quantity of errors detected over a period of time on the DSL
loop;
adjusting, by the processor, the target noise margin for the DSL loop based on the performance data in order to increase the
DSL data rate and to reduce the quantity of errors detected over the period of time;
wherein the target noise margin is inversely associated with an establishable DSL data rate;
thereby allowing a sustainable increased data rate while reducing the quantity of errors detected over the period of time;
detecting, by the processor, whether the DSL loop is identified as a newly upgraded loop; and
in response to increasing the target noise margin for the DSL loop identified as a newly upgraded loop, removing a newly upgraded
status from and scheduling the DSL loop for performance data retrieval and error assessment at an interval of time of less
than or equal to the period of time.
