Methods and systems to improve accuracy and fault detection capability of automated line diagnostics through at least one of: joint processing of SELT and DELT data; comparisons of relative strengths of peaks and/or dips to envelope and/or peaks to dips in a time domain echo response; and iterative diagnostics whereby an echo response is adjusted through signal processing techniques, for example to remove lengths of straight line, between successive performance of a detection algorithm. More than one of the diagnostic systems and methods described herein may be employed in combination to improve accuracy and fault detection capability. For example, where SELT and DELT data are jointly processed, analysis of the SELT data may employ the ratio tests described in the context of a SELT diagnostic routine. Similarly, the SELT diagnostics method assessing relative strengths of peaks and dip in an echo response via ratio tests may be combined with iterative adjustment of the echo response.
