A prequalification determination is made on a DSL line to predict the bit rate improvement that might be accomplished by implementation of vectoring, providing information to use in determining whether or not to implement vectoring. Overall noise is measured on the line, along with FEXT noise, and the FEXT noise is subtracted from the overall noise, and the resulting value is employed to determine a predicted bit rate, providing an indication of the potential bit rate if vectoring is implemented. |
