An efficient troubleshooting testing scenario for IPTV over DSL lines: Practical examples

This paper continues already done research on the possibility for implementation and new test scenarios application for the problems detection in IPTV services delivered over DSL lines. Compared to the previous paper which research it continues, this paper provides a few specific examples of DSL lines in which, based on the values of physical layer parameters, we can assume with great certainty the real cause or a number of possible causes of problems in the IPTV service function. In this way the efficient elimination of identified problems is enabled.
