Automation of measurement of transmission properties of DSL modems
 Pokorný, Lukáš ; Šedý, Jakub (referee) ; Šilhavý, Pavel (advisor)
The work deals with transmission parameters of DSL systems and software development for the automated measurement. The first part is devoted to the transmission medium and modulation techniques. The following describes the detailed functions and features of ADSL2+ modems. Integral part of the work is the overview of the ITU test methodology, together with parameters of test loops and types of interference. Within the automation of measurement are described used Spirent simulators DSL414E and DLS8234 and important communication commands. The practical part is devoted to designing applications for control simulators and software for automated measurement. For implementation of algorithms and creation of graphical interface is used C++ programming language. Finally the results of measuring the transmission properties of ADSL and VDSL systems executed by created application are presented.
