System and method to reduce crosstalk of digital subscriber lines

摘要

A computer implemented method includes determining crosstalk characteristics of a plurality of digital subscriber lines. The computer implemented method includes identifying pairs of digital subscriber lines, each of the pairs including a first digital subscriber line and a second digital subscriber line, where the first digital subscriber line has a crosstalk characteristic that is correlated to the second digital subscriber line. The computer implemented method also includes rearranging terminations at an access node to assign at least one of the identified pairs of digital subscriber lines to a common vectoring group.

1. A method comprising:
identifying a crosstalk characteristic of each of a plurality of digital subscriber lines; identifying a pair of digital subscriber lines from the plurality of digital subscriber lines, the pair of digital subscriber lines including a first digital subscriber line and a second digital subscriber line, wherein the crosstalk characteristic of the first digital subscriber line has a correlation to the second digital subscriber line; assigning the first digital subscriber line, the second digital subscriber line, or both, of the pair of digital subscriber lines to a common vectoring group, wherein the common vectoring group has a threshold number of digital subscriber lines; and reducing an amount of a particular crosstalk characteristic of the first digital subscriber line, wherein reducing the amount of the particular crosstalk characteristic includes modifying, at a digital signal processor, a first signal corresponding to the first digital subscriber line based on a second signal corresponding to the second digital subscriber line, wherein the particular crosstalk characteristic of the first digital subscriber line is caused by the second signal.
