A comparison between different physical layer parameters testing scenarios

This paper analyses the test scenarios of monitoring platforms of DSLAM devices and hand-held test instruments in terms of testing the physical layer parameters for the detection of problems in the functioning of the IPTV service. The paper carries out a comparison of both test abilities and analyses the advantages and disadvantages of each in comparison to the other. The paper also suggests optimal use of both test scenarios at very frequent testing on DSL lines.
