Analysis and Design of Switching Components for a TDM Communication System.

In modern communication systems, expansion of facilities without increases in cost or size of plant is a goal. Time Division Multiplexing TDM can achieve this goal by using sophisticated hardware. Improvements in signal path components such as contacts, filters, and gate driving circuitry give the desired level of sophistication. JFET technology is shown to be useful for contact circuits, while giving good transmission performance. PCAP Princeton Circuit Analysis Program simulation and hardware modelling are used to illustrate and substantiate Resonant Transfer TDM concepts. The purpose is to propose elements of a TDM switch meeting future requirements using the work accomplished here as a basis. The system serves 256 lines per highway and is integrated circuit oriented. Capacity is estimated at 2048 lines. Author
