Abstract
A multistage switching facility for optical signals where time conversions are only used in the last stage while only space and frequency conversions are used in the other stages. The last stage contains space, time and frequency position converters resulting in a facility in which no signal overtaking is possible when multiple routing is provided in the switching facility.
