a) performing a frequency domain reflectometer sweep of the cable network generating raw data with a plurality of reflections, each reflection having a peak value;

b) removing all reflections having a peak value less than a predetermined peak threshold value;

c) determining and removing second and third harmonic reflections;

d) determining and removing side lobe reflections to generate filtered data;

e) determining which reflections in the filtered data represent unterminated cables by comparing the peak values with a predetermined open threshold value;

f) determining type and position of any splitters in the cable network from the filtered data;

g) determining position of any barrels in the cable network from the filtered data; and

h) displaying the type and position of the unterminated cables, the splitters and the barrels

wherein step f) includes searching the filtered data for a collection of peaks corresponding to a known collection of peaks representative of a splitter; and

wherein one of the known collection of peaks indicative of a two-way splitter includes a first reflection followed by two larger reflections at different distances.
