A circuit switched switching system and method includes a plurality of matrix transposition memories. The memories permute the order of incoming and outgoing data, and thereby increase the efficiency of the switch. The switch and matrix transposition memories may be disposed in a satellite. The switch may further include batching circuits for grouping together data from a single terminal device for more efficient transmission through the switch and for more efficient error correction.
