ABSTRACT:
The recurring time slots in each line of a time division multiplex communication system are identified by a unique combination of phase relationships among a plurality of synchronization signals. Each of a plurality of terminators sends and receives samples of input and output data to and from an information path consisting of a bundle of discrete lines or buses. Any particular connection involves only on a selected line or lines and is gated to appropriate terminators only during recurring preselected time slots and only via a selected line or lines. Time slots are identified by a unique combination of phase relationships occuring in a separate synchronization path.
