Telecommunication Networks Laboratory

The basic principles explored in the PSTN and VoIP switching course are essential for technicians and engineers studying modern electronic switching in conventional Public Switched Telephone Networks (PSTN) and Voice over Internet Protocol (VoIP).

The Telecommunications Networks laboratory integrates state-of-the-art hardware with interactive courseware in a real electronic exchange. The system is controlled by the student’s PC, as practical exercises are completed to reinforce learned theories. Each experiment is accompanied by detailed procedures to guide the student through every experiment with a minimum of instructor intervention.
