METHOD FOR MEASURING THE DURATION OF PHENOMENAS IN COMPUTER-CONTROLLED FACILITIES, IN PARTICULAR FOR MEASURING TRAFFIC IN TELECOMMUNICATIONS FACILITIES

摘要

P Method for measuring the duration of phenomena in installations controlled by a computer, in particular for measuring traffic in telecommunications installations. /P P In an installation comprising a progressive counter V and a regressive counter R, these counters execute the same number 16 of steps before simultaneously reaching the initial value 0000, the cycle of a counter being greater than the observation time P, and there is provision for each switching member to observe a totalizing counter T, to the content of which is added at the start of a phenomenon E the counting state of the counter R and the end of the phenomenon the state for counting the counter V, and for dcs phenomena E of a duration greater than T, the end of the latter is considered to be the end of an interval and the start of a new interval. /P P Application in particular to telephony installations. /P
