Abstract
A single-stage grooming switch is provided for switching streams of multiplexed traffic, such as SONET STS-48, in both time and space domains. In particular, the switch implements a distributed demultiplexing architecture for switching between any input timeslot to any output timeslot at a reduced layout size. Furthermore, the distributed demultiplexing architecture results in low latencies being associated with reconfiguration of output permutations on the order of nanoseconds.
