Abstract: Apparatus, methods and articles of manufacture to predict vectored digital subscriber line (DSL) performance gains are disclosed. A disclosed example method includes determining a model coefficient of a noise-to-margin ratio (NMR) model from performance data measured for a DSL subscriber loop prior to provisioning of vectoring for the DSL subscriber loop, computing, using the model coefficient, a first NMR value with disturbers enabled and a second NMR value with disturbers disabled, and estimating an expected vectoring performance gain for the DSL subscriber loop based on the first and second NMR values.

Abstract: Example methods, apparatus, and articles of manufacture to trigger preemptive maintenance of vectored digital subscriber line (DSL) systems are disclosed. An example method includes generating a trouble ticket for a first subscriber loop based on a result of a diagnostic test, the diagnostic test being performed on the first subscriber loop when a value representing crosstalk coupling between the first subscriber loop and a second subscriber loop exceeds a threshold. The first subscriber loop and the second subscriber loop belong to a vectored group of subscriber loops contained in a same cable binder. The example method includes submitting the trouble ticket.
