Abstract: The invention measures the rates of a whole population of existing lines together with a line characteristic, such as capacitance, that can be measured prior to provisioning. Using these measures, a rating we refer to as a “quality figure” is generated for each distribution point by looking at the rate of the lines running through that distribution point, and comparing those rates to the rates of other lines having the same line characteristic across the whole population of lines. Distribution points that have lines operating better (faster) than the average for their given line characteristic will have higher quality figures. To estimate the rate of a new line, the quality figure of the distribution point that the new line passes through is used in conjunction with the measured line characteristic as a look up on the whole population of lines.
