Dimitrios K. Lymberopoulos, G. Kokkinakis · Electronics Letters · 1987
A method for fast and economic acquisition of analytic subscriber traffic data in conventional electromechanical telephone exchanges is described. The method is based on a specially designed microprocessor-controlled scanning device and on algorithms constructed according to the statistics of the registered call phases. The method has been successfully implemented in the local telephone network of Patras, Greece.
