Communication switching system, with marker, register, and other subsystems coordinated by a stored program central processor
US 3835260 A
A stored program computer is used for functions such as digit analysis and routing control where flexibility is important, while a wired logic time division multiplex register-sender subsystem is used to receive dialing and other call signals and to control outpulsing which require relatively fixed functions of a repetitive nature. A reed relay switching network is controlled by wired logic markers which perform path selection functions as well as supplying operating potentials for the network relays. The originating marker also performs the function of scanning the lines for originating calls, identifying the calling line and selecting a path through the network to a register junctor. Direct data communication is provided between the originating marker and the data processor computer for sending an originating message identifying the calling line and the register junctor. There is also a direct communication path from the computer to the terminating markers to send them messages identifying terminals to be connected to complete a call. The data processor includes a separate drum memory system with its own processing logic circuits for performing functions such as translations and providing an extended memory for some programs for the computer. The data processor computer communicates with the register-sender subsystem by direct access to the register-sender memory on a random basis, arranged so as not to interfere with the cyclical access by the register-sender subsystem.
