PREQUALIFICATION OF VECTORING BEFORE IMPLEMENTATION

摘要

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.

主权项

1. An apparatus for prequalification of vectoring before implementation, comprising:
a noise measurement apparatus for measuring overall noise and providing an FEXT noise value; and a calculator for determining bit rates with the overall noise, and the bit rates with overall noise minus the FEXT noise.
