摘要： PURPOSE:To improve speed for communication while keeping the high speed for frame processing by providing a competition circuit equipped with an access control function and a guarantee function in the peripheral circuit of a frame memory. CONSTITUTION:In the peripheral circuit of a frame memory 31, a competition circuit 19 is provided with the access control function to control the read of a data from the frame memory 31 by monitoring a control signal showing the condition of access from a control processor to the frame memory, and the storage guarantee function to guarantee the buffering of the frame memory 31 by counting the control signal and limiting the memory access of the control processor when the count value exceeds a prescribed value. Therefore, the control processor enable arbitrary access to the frame memory 31 and even on the side of the frame processing, the time for buffering to the frame memory 31 is guaranteed. Thus, the speed for communication is improved while keeping the high speed for frame processing.

摘要： PROBLEM TO BE SOLVED: To provide a voice data relay method and system for avoiding deterioration in call quality by maintaining a call state before system switching even when having a multiplexing configuration. SOLUTION: The voice data relay method and system are composed so as to relay voice data via a plurality of gateway devices respectively having the multiplexing configuration between a subscriber's telephone and a packet network. One of the gateway devices is set to an operation system and the rest of the gateway devices are set to a standby system. The voice data are transmitted between the subscriber's telephone and the packet network via the gateway device set to the operation system. Replicated data including the same contents as those of the voice data are generated so as to supply them to the gateway devices set to the standby system. The transmission of the voice data includes an operation for transmitting at least a part of the replicated data received by the gateway device set to the operation system during a period when the gateway device set to the operation system is set to the standby system as the voice data.

摘要： PURPOSE:To disperse a load and to prevent the load from being increased by receiving the various information of frames accumulated in an input buffer means from a frame status receiving means and multiply transmitting the frames as cells by a transmission control means. CONSTITUTION:When the frames are transmitted to input buffer circuits 30 (30-1-30-n), a control processor 1 writes the various information of the frames to a frame status reception circuit 32. According to these information, a frame disassembling device 3 confirms frame reception and generates the address of the frame stored in the circuits 30 form address information. According to the information from the circuit 32, a transmission control circuit 38 alternatively reads out the frames stored in the circuit 30 only for fixed lengths and outputs them while multiplexing the cells. Thus, transmission can be prevented from being temporarily concentrated in a specified destination and the increase of the load can be prevented.

摘要： PURPOSE:To improve real time property by using hardwares to constitute respective constitutional elements of a packet disassembling part. CONSTITUTION:A packet disassembling processing pat 50 is constituted of the packet disassembling part 50a whose respective elements are constituted of hardwares and a control processor 50b. The control processor 50b sends information, e.g. various information format information with an optional length to which destination and information are added, sent from an originating side terminal to the packet disassembling part 50a. The disassembling part 50a converts the various information format information sent from the control processor 50b into packeting information P. At the time of receiving the information P through a packet switch 20 connecting a terminal interface part 10 to the processing part 50, the interface part 20 converts the information P into the information format of the terminal 1 and transmits the converted information to the terminal 1.

摘要： PROBLEM TO BE SOLVED: To attain the easy application even of a system where the number of signal lines is physically limited or the installation is difficult for an exclusive cable itself by detecting a power failure to a monitoring object device based on the signal level of a time division signal specifying position given from the monitoring object device.
SOLUTION: If the supply of power is cut to a device B, the supply of power is also cut to a power monitoring part 14 and a serial bus in interface 15 contained in the device B. Thus, the part 14 and the interface 15 cannot actively operate and the potential of a serial bus cable 16 becomes deficient. A serial bus interface 13 of a device A, i.e., a monitoring main body device is designed based on fail-safe and accordingly the signal of monitoring information corresponding to such as unsteady state is raised to an H level. Thus, the monitoring information which are given to a power supply cut detection part 11 from a power monitoring part 12 are consecutively set at H levels. As a result, a power supply cut state of the device B is detected.

摘要翻译：要解决的问题：即使是通过基于信号电平检测监视对象装置的电力故障，甚至可以容易地应用信号线的数量被物理限制的情况或专用电缆本身的安装困难的系统从监视对象装置给出的时分信号指定位置。解决方案：如果电源供应切断到设备B，则电源供应也切断到设备B中所包含的接口15中的电源监控部分14和串行总线。因此，部件14和接口15不能主动操作，并且串行总线电缆16的电位变差。设备A的串行总线接口13，即监视主体设备是基于故障安全设计的，因此与诸如非稳态的对应的监视信息的信号提高到H电平。因此，从功率监视部12向电源切断检测部11提供的监视信息被连续设定为H电平。结果，检测到装置B的电源切断状态。

摘要： PURPOSE:To efficiently utilize a memory and to rapidly execute information processing by storing a header formed by the 1st processing means and an information field protocol-processed by the 2nd processing means in a common storage means. CONSTITUTION:When frame information is transferred from a transfer control processing part 10 to a transmission frame memory 23 in an inter-processor common memory 20, a microprocessor(muP) 13 writes the leading address of the information and the number of bytes in a PR2 interruption control part 24. The control part 24 executes the interruption processing of the muP 31 in a protocol processing part 30. The muP 31 inputs the contents of the information field of the frame information in a memory part 33 and executes the protocol processing of the contents of the information field. After ending the protocol processing of the muP 31, a memory access control part 32 writes the contents of the information field in a transmission frame memory 22 and writes the leading address of the written contents and the number of transfer bytes in a register of a PR1 interruption control part 21.

摘要： PURPOSE:To correct efficiently the error of the clause punctuation by pointing the error of the clause segmentation from the solid writing character string, and providing the key for instructing to segment the next clause candidate and convert it again. CONSTITUTION:The character string inputted from a keyboard 1 is stored at a character buffer 2 until the string comes to be the chance of the KANA (Japanese syllabary)-KANJI (Chinese character) conversion, and when a converting processing part 3 decides that the string is the chance of hte KANA- KANJI conversion, the dictionary of a word storing part 4 is referred to, the KANA-KANJI conversion is executed and displayed in a display 5. When an operator discovers the clause punctuation error, by pushing down the clause next candidate key, to the character string having the punctuation error, the KANA-KANJI conversion is executed and displayed by another clause punctuation.
