Abstract:

Several different types of matrix configurations were studied. Calculations were made to determine the probability of blocking, number of crosspoints and grade of service for each of the types considered. The results of these calculations are shown and 2 basic matrix configurations are examined in detail. The 4 layer PNPN switching device was completely explored and the results are illustrated, indicating the feasibility of the device selected to perform the switching functions required in the matrix. Tentative circuit configurations for the matrix are shown along with a circuit diagram of a send and receive path employing the PNPN device. Author
