Abstract
A method and apparatus for modeling a network comprising a plurality of transmission lines is described, the method and system being adapted to measure loop parameters of first transmission line to provide measured loop parameters, determine a topology of the first transmission line by analyzing the measured loop parameters with reference to at least a one model of a plurality of models for transmission lines of different topologies, select a further model for estimating crosstalk related parameters based on the determined topology, and estimate at least one crosstalk related parameter based on the determined topolgy and the selected further model.
