ABSTRACT:
The invention described is an electronic device for traffic measurement in telecommunication networks. The device measures the two main parameters of the carried load, known mathematically as the mean and variance of the number of calls in progress from which the mean of the offered load and its peakedness are calculated by mathematical formulas. The device monitors continuously the service channels and records the highest load in a period of sixty consecutive minutes or part thereof. The device also records the number of times when all the service channels are busy or when a certain threshold is reached and provides the facility to record the load during individual group busy hour as well as during the cluster busy hour. (A cluster is defined as a number of cooperating trunk groups with coincident or noncoincident busy hours.)
This invention is further believed to be the first attempt to obtain an accurate estimate of the offered load and its peakedness from mean and variance statistics of load carried on a sampled portion of the total number of trunks in each trunk group. Therefore it represents a new concept and significant departure from present-day traditional methods which date back to the Twenties.
