MEASUREMENT OF DELAY VARIATION IN DIGITAL COMMUNICATIONS NETWORKS

Kurt Hilty, Jean Philippe Mellana

Abstract:	A method to measure the slow delay variations (wander) in digital transmission networks, while normal traffic is in progress, has been developed. The measurement system uses the TV-broadcast system as common reference time base. There is no need to loop back the lines nor to prepare them in a special way for the measurements. The system is observing the traffic on the transmission lines in a passive mode. Measurements has been carried out on an optical 140 Mbit/s point-topoint transmission system of 50 km length.
