Switching method for integrated voice/data communications.

摘要

In a communication system, integrated switching of voice and data is provided between terminals or lines (800) which are connected through switch adapters (301...332) to a switching matrix (50). In a first adapter, voice samples bound for the same destination or second adapter are grouped into a frame. Connections are then established between the two adapters and the frame is transmitted therethrough. This is repeated cyclically for all pairs of adapters between which transfer of voice is required. Duplex transmission can also be accomplished by transmitting two frames simultaneously in opposite directions through a dual connection in the switching matrix. Asynchronous data (i.e. data not requiring synchronous transmission) is switched by storing these data in respective separate memories (26; P0...Pm) of each source adapter, wherein each separate memory corresponds to a particular destination adapter.
