Abstract
A time folded time space time (TST) switch with the establishing of a communication through path in one direction automatically establishing a path in the opposite direction in an adjacent time slot. With one transfer through a space switch made during an even time slot, the other transfer is made in a symmetrical fashion during the following odd time slot. This time folded TST switch selectively interconnects digital bi-directional Time Division Multiplexed (TDM) transmission paths.
