Abstract
The invention pertains to a method and apparatus for testing a component of a vectoring system, such as a DSLAM performing crosstalk cancellation. The method is based on the insight that line termination equipment, such as a DSLAM, and in particular the crosstalk canceller, can be used to simulate a multiline network. A signal is exchanged between the line termination equipment and attached network termination equipment, passing through the crosstalk canceller which acts as a multiline simulator. Information indicative of an error component in a received version of the signal is used to assess the operation the vectoring system.
