Abstract
A system for performing a single ended line test (SELT) of a selected subscriber line within a bundle of in-service subscriber lines each supporting frequency division multiplexed multi-tone modulated XDSL communications. The system comprises: a crosstalk cancellation module and a SELT module. The crosstalk cancellation module is coupled to the subscriber lines and configured to cancel crosstalk between the selected subscriber line under test and the in-service subscriber lines. The SELT module couples to the crosstalk cancellation module and is configured to coordinate SELT testing with the crosstalk cancellation module to cancel crosstalk between the selected subscriber line and the in-service subscriber lines during testing.
