Abstract

A polyphase rotating-access switch consists of a set of latent space switches connecting a set of ingress switch modules to a set of egress switch modules. Each latent space switch has a primary rotator connecting each ingress switch module to each transit memory device of a bank of transit memory devices during a rotation period and a secondary rotator connecting each transit memory device to each egress switch module during the rotation period. Each latent space switch provides paths from each ingress switch module to all egress switch modules characterized by switching delays having values between zero and a rotation period. For each pair of ingress and egress switch modules, the set of latent space switches provides paths of different delays having values between zero and a rotation period. Thus, a connection from an ingress switch module to egress switch module may select an available path of least switching delay.
