Abstract
The loop length, the number of bridge taps and the length of the bridged taps can be estimated by comparing through the use of differential evolution a measured frequency domain channel impulse response of the transmission line to a model of a transmission line that is composed of multiple sections and multiple bridge taps. The diagnostic and test information describing the condition of the line can then be exchanged, for example, by two transceivers during a diagnostic link mode, or the like.
