摘要： PURPOSE:To improve the processing performance of a central processing part by interrupting the central processing part when an excellency signal shows defection during a read of return data. CONSTITUTION:Information is sent to device 13 to be controlled via input-output interface part 12 by the output instruction of central processing part 11. On the basis of this information, device 13 to be controlled operates and sends an excellency signal regarding its operation result and return information to input-output part 12. Then, central processing part 11 counts the time until the excellency signal from device 13 to be controlled is sent back to input-output part 12 after the output instruction. When the excellency signal is not returned from device 13 to be controlled in a certain time, input-output part 12 discriminates defection and interrupts central processing part 11 via interruption line 21. Thus, an input instruction for the confirmation of the excellency signal from central processing part 11 can be omitted, so that the processing performance of central processing part 11 is improved.

摘要： PURPOSE:To restart call processing rapidly even in in-use/stand-by switching by saving call data without adding special hardware, by using the connection route between CPU, performing ordinary call processing, and a peripheral processor. CONSTITUTION:Through inter-processor communication lines 201a and 201b, CPU50 and doubled peripheral processor 21 are connected together and line concentrator 11 is connected to processor 21 to constitute the exchange system. Processor 21 of this system is provided with peripheral processor memory units 211a and 211b, microprocessors 212a and 212b, and communication controllers 213a and 213b respectively and while one system is used as in-use one, the other is used as stand-by one. Call information stored in memory unit 211a or 211b of the in-use system is transferred to CPU50 at the interval of a constant period or constant process and further transferred to memory unit 211b or 211a of the stand-by system to save the call information, so that the call processing can be restarted rapidly even in in-use/ stand-by switching.

摘要： PURPOSE:To obtain an economical switchboard system, by providing a processing part to each function block which forms a switchboard system and securing an interface between the blocks by the loop connection. CONSTITUTION:A switchboard shown in the figure includes the subscriber sybsystems 20 and 30 which give the time division line concentration to the subscribers 200-301, a network subsystem 40 using a time division switch, a register subsystem 50, trunk subsystems 60 and 70, a central control subsystem 10, an operation subsystem 90 and a maintenance subsystem 80. Each of these subsystems contains processing parts 21, 31, 41, 51, 61, 71, 81 and 91 plus a central control processor 11 that control the job proper to each function. these subsystems are connected to each other by loop communication lines 00 and 01 and via loop communication control circuits 22, 32, 42, 52, 62, 72, 82, 92, 12 and 13 respectively to transmit and receive the necessary control information. The subsystem 10 gives the centralizing control to the operations of other subsystems.

摘要： PURPOSE:To perform maintenance and operation without using a private line by making transfer of alarm information from an exchange to the center, and transmission and receiving of system rise start information and exchange system test information from the center by ordinary call procedure. CONSTITUTION:A maintenance center MC is connected to a remotely maintained office through the first and second repeater stations and given a subscriber's number as a subscriber's terminal of the second repeater station. A remotely maintained office is provided with a subscriber's circuit SC, a trunk NW, a central control processing equipment CC, an alarm controllr ALMC, an emergency circuit EMA and an alarm sender ALMS. The alarm sender ALMS receives information that abnormality occurred in the system of a remotely maintained office from the controller ALMC and informs the center MC, and consists of a pseudo trunk P-OGT that is opposed to an incoming trunk of the first repeater station, a MODEM used for transmitting and receiving information to and from the center MC and a control circuit ALMSC.
