Abstract:
Three-stage switching network for digital, time division multiplexed channels that is structurally extendable may be constructed by placing on a single structural unit an input buffer with connection to one column of an orthogonal crosspoint matrix, an output buffer, a row of crosspoint gates with connections to all columns of said orthogonal crosspoint matrix, and transfer control logic.
