<p>This invention relates to a peripheral control unit for a digital switching system. It utilizes a peripheral control network formed of combination time and space division switches which communicate with peripheral cards using a number of time divided lines (channels of which correspond to peripheral units), and communication with the main system central control using a parallel bus connected to a controller and a transceiver, which is connected to the system control via serial time divided lines. In this manner a very few number of wires is required to be connected to the peripheral cards, while allowing selectively simple communication structure and high reliabiity.</p> |
