Abstract
This invention relates to a method of switching voice and data over a multistage interconnection network (MIN). More specifically, a plurality of bits are stored in respective storage locations of the switching elements of the MIN. Storage location of a switching element represents a particular time slot in a frame or a sequence of frames. Bits stored in each location represent specific conditions of the inputs and outputs of the switching elements and also indicate which inputs of the switching elements will be connected to which outputs of the switching elements. This storage of control information in the switching elements allows the switching network to rapidly and simultaneously change connections through the switching elements of the network.
