  • Statistical multiplexer with dynamic bandwidth allocation for asynchronous and synchronous channels
    Patent number: 4494232
    Abstract: A statistical multiplexer is disclosed that includes interfaces for asynchronous and synchronous data equipment, and a CPU/control logic. The CPU/control logic cooperates with the interface for the synchronous data equipment for allocating bandwidth to synchronous data equipment when bandwidth is requested and for deallocating bandwidth when bandwidth is no longer required. The allocation and deallocation of bandwidth is controlled by predetermined control frames generated by the CPU/control logic. Such control frames are responded to by the synchronous data equipment interface of the multiplexer originating the control frame and the synchronous data equipment interface of the multiplexer receiving control frames.
