Abstract :
End-to-end telecommunication network simulator design and realization is described in the paper. The main applications of the simulator are conversational tests e.g. as per ITU-T P.800 and demonstrations. The simulator can be also used as a replacement of telecommunication chain part that is missing during end-to-end testing or measurements. Examples of achieved subjective test results are presented.
