Abstract
A single ended, frequency domain reflectometry signal processing based scheme measures loop loss of a telecommunications wireline. A distortion-corrected, normalized data array is differentially combined with an associated set of wireline noise spectrum values. The resulting noise margin data is processed by a Shannon Theorem operator, to produce a set of N frequency bins, each containing the number of bits which the link will support for a respective tone. The bit contents of the bins represent a composite bit rate that is available for use for ADSL signalling.
