ABSTRACT OF THE DISCLOSURE A microprocessor control complex for a telecommunications switching system disclosed in the context of a digital time division multiplex switching system. The control complex is arranged as a cluster of hardware identical microprocessors in a distributed processing configuration wherein each microprocessor is provided with its own memory and clock and is programmed to perform a portion of the total function of the switching system. Each microprocessor performs the functions assigned to it independently and asynchronously of the others. Data is transferred between microprocessors in a manner which minimizes the amount of time spent in interprocessor communication. This communication is accomplished via interprocessor buffers which provide dedicated communication channels between partner processors while allowing those processors to continue to operate asynchronously. The distributed control complex allows the software to be modularized with resulting economics in program generation and debugging. -1-
