ABSTRACT:
The loop switching system of this invention overcomes the problems of prior art loop switching systems by providing dynamic rearrangeability of loop switching systems. In particular, the subject loop switching system is comprised of a number of port circuits or nodes serially connected together to form one or more loops. The interconnection of these various ports into one or more loops is implemented on a dynamic basis by means of a central switching matrix.
