Abstract
The present invention concerns methods for estimating one or more transmission properties of a telecommunications transmission line. Estimates of the line input impedance, Zin at a frequency ƒ, and the line capacitance Ĉ are made. An estimate is then made in dependence of Ĉ, the frequency ƒ and a value Γ, where Γ satisfies the relationship Γ coth (Γ)=Zin·jωĈ, and ω=2πƒ. Accuracy may be improved by least squares fitting a curve to a set of intermediate values and then generating an estimate from the coefficients of the curve.
