Abstract

This article describes the design of a semi-static switch, called rotary switch, for Tl (2 Mbps) to Tl and ECL (4 Mbps) to ECL space switch. The design can be easily extended to switch even higher speed lines. The innovation is the access protocol for the automatic control of a cross-point switch. 3 p. The general switch configuration is shown in Fig. 1. The switch is based on an N by N cross-point matrix. The N input ports and N output ports are grouped into n sets with P=N/n ports in each set. At input, a set of ports is connected to an input adapter which can multiplex k input lines into P ports. Similarly, at output, a set of ports is connected to an output adapter which can de-multiplex P ports into k output lines.
