PURPOSE:To secure the connection between the terminals accommodated in another line and to improve the service and reliability of a control device by diffusing and controlling plural time division switch by plural peripheral control circuits. CONSTITUTION:Plural terminals T0-Tn are housed in a time division channel control device 100 through communication line 110-11n, and each line control circuit 120-12n is connected with the line 110-11n, and the demand signal from each terminal T0-Tn is transmitted to peripheral control circuits 150-15n. The main control circuit 16 is connected with each control circuit 150-15n and each control circuit 150-15n is monitored and controlled. In addition, communication lines 110-11n are controlled by division switches 130-13n dividedly provided according to each route 120-12n and controls the reading and writing of the control circuit 150-15n. Timing occurrence circuits 140-14n read to switches 130-13n, send the written clock signal to secure the connection between T0-Tn housed in another circuit. |
