Abstract
Improved diagnostics of transmission line noise are enabled by adapting DSL equipment to make measurements of quiet line noise also in the transmit bands, so that noise can be measured at both ends for the same frequency or frequency bands.An estimate of the point where noise enters the line, as well as an estimate of the noise power at that point can be made from the relationship between the so measured noise levels at both ends of the line.
