PURPOSE:To simplify the connection control between circuit-signal concentrating- expansion parts and a circuit signal bread-down-makeup device by controlling connections among those devices by one switching memory, by providing a switching gate circuit among them. CONSTITUTION:This system is provided with a plural number of circuit signal concentrator-expanders A0, A1, and A2 which concentrate and expand signals from a plural number of circuit groups G0, G1 and G2 through respective circuits, and switching gate circuit SWG, which is arranged among devices A0, A1 and A2, controlling transfer signals. Further, circuit-signal breakdown-makeup device SSR, which changes signals from circuits or signals from the switching unit to respective circuits into the information states of corresponding destinations, is connected to circuit SWG. Next, switching memory units SWM and CPU are connected between device SSR and circuit SWG; device SWM is stored with information for circuit connection setting, and the CPU makes the administration and control of device SWM, so that the connections between devices A0, A1 and A2, and circuit SWG will be controlled in a time-division mode. |
