摘要： PURPOSE:To simplify the function and constituion of the regulated ground identifier, by controlling the reception of the regulated information with the upper rank station and the test call for the communication line test unit, taking into consideration the signal processing function of the communication line test unit at the time sharing exchanger. CONSTITUTION:After transmitting and receiving the start signal and the start completion signal for the regulated information delivery between the upper rank station 1 and the lower rank station 2, the regulated information from the upper rank station 1 is assigned to the specific time slot via the carrier unit 5 and the A/D converter 27 and it is received at the signal reception trunk 31. The central control unit 7 feeds instruction to the control unit 26 after interpreting the reception signal and grouping instruction is delivered to the terminal station 3 via the regulated ground identifier 21. Further, when the test call from the upper rank station 1 is identified, the specific time slot is connected to the exclusive use time slot for regulated ground identifier on the test highway 34 from the digital switch section 33 and the ground number information is waited.

摘要： PURPOSE:To simplify the control of a line concentration stage, by giving a logical 2-tier control and thus secure a separation of function among the processors as well as the independence of function. CONSTITUTION:The line concentractor LC that performs a concentration of subscriber lines consists of the line concentration control processor LC-LNP that performs controls within the LC plus the line concentration channel device LC-SP that stores a plural number of subscribers SUB. The calling of the SUB connected to the LC is sent to the trunk control processor TKP within the distribution stage device DIS-SW via the control information line LINE. The processor TKP transfers the information to the processor CP from the information bus BUS without giving any logical decision if the information is addressed to the central control processor CP. The logical decision of the calling detection signal is controlled by the processor CP, and a connection is given between the originating register trunk within the trunk device group TRK and the call line SP between the LC and the SP for reception of the dial figures of the SUB. Thus an isolation is secured for the controls among the processors.

摘要： PURPOSE:To enable to reduce the processing interrupting time against failure, by performing memory protection check at the same time as write-in to an existing storage device and making write-in to a spare system storage device after the memory protection check. CONSTITUTION:Processors CC#0, CC#1 read required information from an existing storage device and write in the processing information to the existing storage device IM#0. In this case, the result of the memory protection check at the device IM#0 is transmitted to the processor CC#0, and the check for the spare storage device is made thereafter. If normal, the CC#0 writes in the information to the spare storage device IM#1 for processing with the existing device. If not normal, the processing is interrupted at an interruption request signal IS, the information FFG at the interruption is written in the specific area of the device IM#0 for saving. A system managing device SCTL which stops the device CC#0 with an emergency circuit EMA sets the information saved in the specific area of the IM#0 to the CC#1 to change the device IM#1 into the existing device.

摘要： PURPOSE:To prevent the competition of events transferred between processors unitedly by giving discrimination information to a call in exchange processing and by referring to the discrimination information. CONSTITUTION:Trunk control processors TKPi and TKPj are connected respectively corresponding to digital signal processors DSGE, and the multiprocessor exchange processing system is composed of call processors CPi and CPj with decentralized loads, common memory CM, and network NW. When CPi accepts the start of a call, the call is given ID as an identifier, and a circuit number is also given ID as a circuit event and sent to CPi, which stores CM with it. To TKPj for the call, an event of ID and the circuit number is sent and, while stored, sent to CPj. When this event is received, CPj collates ID of an assigned event with that of the event from TKPj and, when those IDs agree, executes the event.

摘要： PURPOSE:To attain the efficient interruption processing having the flexibility in matching with a system, by setting a fixed priority as to a specific interruption request, and not fixing the priority as to another interrupting request. CONSTITUTION:When interruption request signals REQ1-REQ4 are generated, they are latched to an interruption request latch circuit 1 in synchronizing with a clock signal CLK to a request latch circuit 1. An output of the latch circuit 1 is applied to a priority control memory 2 as an address signal. Priority data a, b, c from the priority control memory 2 are set to an interruption control register 3 and applied to a request reception signal (ACK) transmission encoder 4 as BCD outputs a', b', c' together with the output of the latch circuit 1. Thus, any of the ACK signals ACK1-ACK4 in response to the priority selection data is transmitted to a central processing unit, and the efficient interruption processing is attained.
摘要翻译：目的：为了实现具有与系统匹配的灵活性的高效中断处理，通过对特定的中断请求设定固定的优先级，而不是固定关于另一中断请求的优先级。构成：当产生中断请求信号REQ1-REQ4时，它们被锁存到与请求锁存电路1的时钟信号CLK同步的中断请求锁存电路1.锁存电路1的输出被施加到优先控制存储器 2为地址信号。来自优先级控制存储器2的优先级数据a，b，c被设置为中断控制寄存器3，并且作为BCD输出a，b'，c'，并将其应用于请求接收信号（ACK）传输编码器4，并将其输出锁存电路1.因此，响应于优先级选择数据的ACK信号ACK1-ACK4中的任一个被发送到中央处理单元，并且实现了有效的中断处理。
