摘要： PURPOSE:To realize the cost reduction for the system not by installing the system switch signal storage display unit independently from the double-structure device against the double-structure device but by dispersing the function of the display unit to each system at the duble-structure part. CONSTITUTION:Trunk control signal processors 50 and 51 feature the double structure, and either and either one of them controls trunk device 70 as the using system. Central control unit 10 sets and stores the using system designation information for the system switch control to one of switch signal storage display circuits 60 and 61. Circuits 60 and 61 feature the function to each other to reset the using system display signal storage of the other side by receiving the using system designation. Then the signal informing wihch one of signal processors 50 and 51 belongs to the using system is transmitted to device 70 from either one of ciruits 60 and 61.

摘要： PURPOSE:To reduce the cost of a decentralized and centralized hydrid control system for a line concentration stage, by managing with one control part in each module by exercising centralized control by normal control parts includes in other modules if one control part runs into trouble at the line concentration state of a digital switchboard. CONSTITUTION:In normal operation, control-line selecting circuit 13 selects control information from control part 12 in module 10 to exercise decentralized control. If control part 2 of module 0 is diabled to operate, the distribution stage side sends a control-line selection signal to control-line selecting circuit 3 via highway 5 and signal inserting-extracting circuit 4 so that circuit 3 will select the control information from control part 12, and consequently line-concentration channels 1 and 11 are brought under the centralized control of control part 12. Prior to the transition to the centralized control mode, path information on module 0 and various information held by control part 2 before the trouble occurs are transferred to control part 12 via common line signal route 7, the distribution stage and common line signal route 17.

摘要： PURPOSE:To reduce the number of digital time division multiple circuits, by providing with a time division jumper circuit and plural digital trunk circuits, and processing the circuit information of various kinds. CONSTITUTION:A signal of 32 time slots on the signal highway 102 from the time division switch 101 is split to each kind of signal by the time division jumper circuit 107, the split signals are connected so as to correspond to the digital trunk circuits 104-106, and the digital trunk circuits 104-106 are able to process an MF receiving signal, an MF transmitting signal and a PB receiving signal, respectively. Accordingly, since it is enough to provide only one signal highway 102 between the time division switch 101 and the digital trunk unit 103, the number of circuits can be reduced.

摘要： PURPOSE:To control both an existing and an auxiliary control devices by one master station, by making one control device communicate with the master station and also testing the other control device by the master station, in two control units connected to the master station through the interface IF equipment. CONSTITUTION:The existing and auxiliary systems between the master station 1 and the IF equipment 2 are connected by the transmission lines 5, 6, respectively, the equipment 2 and both the existing and auxiliary control devices 3, 4 are connected by the IF lines 5', 6' corresponding to the lines 5, 6, respectively, and also the IF line 7 corresponding to the line 6, and the IF line 8 corresponding to the line 5 are connected to the devices 3, 4, respectively. When the normal operation is executed, the master station 1 communicates with the device 3 through the line 5 and the IF line 5', and also the device 4 is tested by the master station through the line 6 and the IF line 6'. When the line 6 is disconnected, the master station 1 utilizes an idle time of communication with the device 3, and tests the device 4 through the line 5, the equipment 2 and the IF line 8 by giving the instruction to the equipment so that the IF line 5' is switched to the auxiliary system IF line 8 connected to the device 4. In case when the line 5 is faulty, as well, the device 3 is controlled by the master station 1 through the line 6, the equipment 2 and the IF line 7.

摘要： PURPOSE:To omit the hardware to store the state information by making the control unit obtain the information concerning the normal and abnormal states of the controlled unit at the execution time of the normal control order, thus ensuring an effective state supervisory for the controlled unit. CONSTITUTION:When the control order is given from control unit 10 to actuate the trunk and trunk driver 70, peripheral control unit 50 receives the order for distribution. And the control signal is transmitted to driver 70. According to this control signal, driver 70 performs the control action. At the same time, whether driver 70 is normal or abnormal is decided by 2nd state information production and transmission circuit 80. In the case of the abnormal state, the contents of that time state information is sent back to unit 50. Unit 50 produces the state information of unit 50 and driver 70 through 1st state information production and transmission circuit 60 to then send them back to unit 10. As a result, unit 10 can obtain the infromation at the time of execution of the control order to each unit based on the normal or abnormal state or the abnormal contents of each unit which is under control of unit 10. Thus the constant supervisory is realized to ensure an effective state supervisory.
