Zusammenfassung:The common control of the switching system comprises two separate subsystems, a stored program data processing unit with a main memory, and a register subsystem with a register memory and a plurality of register junctors in a time division multiplex arrangement. Multifrequency receivers and senders and touch calling tone receivers are connected to the register junctors via a one stage matrix in the register subsystem. The main memory has assignment tables, busy/idle tables and on-line/off-line tables for the receivers and senders which are used with stored program modules to select a sender or receiver, and supply type and address information to the register memory. The register subsystem with hard wired logic operates the matrix to connect the sender or receiver to the register junctor.
