    摘要： A server system constructed by a network using a known PBX in such a manner that information processing terminal equipment and server devices are held in normally-used extensions of the PBX together with other terminals such as telephones, facsimiles, etc. Logical channel numbers of packet links between the PBX and the information processing terminal equipment are assigned to electrically-connected server devices in association with each other and sent to users. The users sends server use data to corresponding destinations by data packets to which the logical channel numbers are applied. The PBX performs a packet exchange process such that the logical channel numbers are respectively associated with physical addresses of the server devices. If the PBX regards the users as improper users, then it does not inform the users of the logical channel numbers. When a logical channel number of a server device used at a user desire is recognized, the user can utilize the PBX server system even if a proper user does not know a physical address of the server device.

    摘要： A trouble processing method of ISDN communication system using an ISDN (Integrated Services Digital Network) and a control apparatus of ISDN communication system. Among a plurality of ISDN communication adapters included in an ISDN communication control apparatus, the same TEI (Terminal Endpoint Identifier) value as that of an active ISDN communication adapter is assigned to its stand-by ISDN communication adapter. The stand-by ISDN communication adapter is made to operate in the same manner as the active ISDN communication adapter with the exception of interruption of transmission of an LAPD (Link Access Producer on the D-channel) to an ISDN. The stand-by ISDN communication adapter is held in the same communication state as the active communication adapter. When a trouble has occurred in the active ISDN communication adapter, the interruption of transmission of the LAPD frame is cancelled and the stand-by ISDN communication adapter is activated as the active ISDN communication adapter. As a result, data communication using an ISDN can be conducted, and recovery processing at the time of occurrence of a trouble in an ISDN communication adapter can be rapidly executed without making the other party of communication conscious of it.

    摘要： The main storage, the communication interface portion and the circuit control module hold transmission data in the buffers until completion of the transmission has been confirmed. When a fault has occurred in the current operating system of the duplexed portions in the configuration elements of the host computer and the multi-circuit control unit, the duplexed portions are changed over from the current operating system to the stand-by system. In this case, information for reproducing data that has been lost due to the change-over is transmitted from the main storage and the circuit control module to the communication interface portion which has become the new current operating system. The communication interface portion which has become the new current operating system restarts the processing based on this information. Data integrity is guaranteed for the data of both directions of transmission and receiving between the host computer and the terminal without mutually confirming the state of data communications before the occurrence of the fault between the terminal and the host computer after the occurrence of the fault. Information exchanges of layer 3 or above are not carried out between the host computer and the terminal. Therefore, overhead of data communications can be minimized.

    摘要： In an ISDN network, data communications can be performed in two communication modes corresponding to line and packet switchings in the same network. The line switching is effective in transmitting mass data to a receiving station and receiving the same therefrom at high speed, and accounting is made to a period of time required for communication in a public network. On the other hand, the packet switching is effective in transmitting low-speed data or small amounts of data produced in a discrete manner, and accounting is made to the amount of transmitted data in the public network.With a valve toward making efficient use of the two communication modes, the present invention relates to a data communication apparatus of the type wherein the two communication modes are changed as needed so as to perform data communications, and to a data communication system suitable for use with the data communication apparatus. In other words, a means for performing data communication continuously over two calls is provided so as to change one communication mode to another under data communication based on a user's request.Thus, when the amount of creation of data varies appreciably under communication, data communication is made based on the optimal communication mode determined according to the amount of creation of the data.

    摘要翻译： 在ISDN网络中，可以在对应于同一网络中的线路和分组交换的两种通信模式中执行数据通信。 线路切换在将质量数据传送到接收站并且以高速接收它们的同时有效，并且计算到公共网络中通信所需的时间段。 另一方面，分组交换在传输低速数据或以离散方式产生的少量数据时是有效的，并且对公共网络中的传输数据的量进行计费。 利用有效利用两种通信模式的阀门，本发明涉及一种数据通信设备，其中根据需要改变两种通信模式以执行数据通信，并且涉及适合于使用的数据通信系统 与数据通信装置。 换句话说，提供了一种用于通过两次呼叫连续执行数据通信的装置，以便根据用户的请求在数据通信下将一种通信模式改变为另一种通信模式。 因此，当数据的创建量在通信中变化明显时，基于根据数据的创建量确定的最佳通信模式进行数据通信。
