Abstract : The study of an electronic switchboard employing negative impedance switching devices in a space division matrix is summarized. It includes the traffic studies, development procedures and circuit design for the switching matrix using fourlayer diodes. Conclusions are given regarding the selection of a four-layer device and its effect on the over-all size and weight of a 200line switchboard. (Author)
