1. A method for rate adaptive digital subscriber line (XDSL) communication, comprising:

  • training an XDSL link for XDSL equipment at a data rate set by a baud rate and a constellation size;

    obtaining actual operating characteristics of the XDSL equipment from parameters for the trained XDSL link;

    accessing one or more rate adaptive data tables storing empirical data for performance of the XDSL equipment; and

    determining whether the trained data rate will provide a desired bit error rate using the actual operating characteristics and the empirical data from the accessed one or more of the rate adaptive data tables.
