Abstract:
1. A loop length system to estimate a loop length of a link comprising: means for estimating a channel transfer function using one or more signals from an initialization, the initialization occurring between a first multicarrier transceiver connectable to a first end of the link and a second multicarrier transceiver connectable to a second end of the link, the one or more signals from the initialization having been transmitted or received using a multiplicity of discrete frequency carriers; means for determining a theoretical channel transfer function of the link; means for comparing the theoretical channel transfer function and the estimated channel transfer function; and means for determining the estimated loop length of the link based upon a result of the comparison, wherein the theoretical channel transfer function has as an input at least one parameter related to a wire gauge of the link.
