An adaptive burst multiplexing system using dynamic deadline computation serializes data from source units. It comprises interface circuits for accumulating in a buffer memory a quantity of data from a corresponding source unit. An empty frame generator circulates a series of frames around a ring through the interface circuit. Each interface circuit computes a deadline beyond which its buffer memory may become saturated and places this deadline in a passing empty frame. When this frame returns to the frame generator it contains the identifier of the interface circuit that put in it the earliest deadline. The generator transmits an empty frame over the ring with the identifier of this interface circuit which then recognizes its authorization to transfer data accumulated in its memory.
