A method is provided that can be used for modifying a control parameter associated with a digital subscriber line (DSL) service. Initially, a real-time performance parameter is received from a first termination unit that is coupled to an DSL circuit. The real-time performance parameter is measured at the termination unit after the termination unit is provisioned and after the DSL circuit is placed in-service. A value of a control parameter associated with the DSL circuit can be modified based on the measured real-time performance parameter. Further, activity over the DSL circuit can be monitored in real-time and when usage of the DSL circuit is below a threshold, the provisionable service parameter that corresponds to the control parameter is modified. Moreover, a first re-provisioning cycle between the first termination unit and a second termination unit coupled to the DSL circuit can be initiated using the provisionable service parameter.
