Abstract:

Investigations continued in the design of a tactical switchboard for voice switching. Blocking characteristics of the proposed three stage network were studied. Curves of blocking prob-ABILITY VS. THE AMOUNT OF TRAFFIC WERE OBTAINED, DEMONSTRATING THE EFFICIENCY OF THE NETWORK. A novel approach to the placement of registers within the matrix, which will produce further improvement in switchboard efficiency, is described. Areas where time sharing techniques and common control operation are most applicable were defined. Four wire balanced vs. four wire unbalanced switching was studied and it was concluded that 4 wire unbalanced switching would prove more economical. Basic timing cycles for the system were established and a detail block diagram of the system was produced. Detail logic design of the system was initiated. Author
