A method for decommutating a variable-synchronization pattern uses a fixed-synchronization decommutator. The method comprises generating N copies of the data stream, receiving one of the N copies of the data stream at a respective one of N fixed decommutator subsystems, receiving synchronized segments of the data stream from each of the N fixed decommutator subsystems at a logical multiplexer, and periodically outputting from the logical multiplexer at least (1/N)th of the synchronized segments of the data stream received from each of the N fixed decommutator subsystems. Each of the N fixed decommutator subsystems is synchronized to a respective synchronization pattern. At least (1/N)th synchronized segments that are sent from each fixed decommutator system are synchronized to the respective synchronization pattern. During each period, the N multiplexed synchronized segments output from the logical multiplexer form a variable synchronized frame of the data stream.
