Claim One:
1. A method for acquiring crosstalk coefficients from a plurality of disturber lines into a victim line in a wired multi carrier communication system, the method iterating through the steps of inserting a plurality of crosstalk proving signals within the wired multi-carrier communication system for probing the crosstalk from respective ones of the plurality of disturber lines into the victim line, carrying out crosstalk measurements over the victim line, and estimating the crosstalk coefficients from the crosstalk measurements, wherein the method iterates through the further steps of organizing the plurality of disturber lines into subsets of disturber lines, and individually assigning disjoining groups of carriers to the respective subsets of disturber lines, wherein the insertion of the plurality of crosstalk probing signals is confined within the respectively assigned groups of carriers, and wherein the subsets of disturber lines and/or the groups of carriers used for a second or subsequent iteration are tailored based on crosstalk characteristics observed for respective disturber lines during a previous iteration.
