摘要： There is a communication system comprising: an integrated services digital network (ISDN) having a plurality of information channels (Bch) and at least one control channel (Dch); a CPU (host computer) connected to said ISDN through a communication control processor (CCP); and a plurality of packet terminals connected to the ISDN. In the communication system, when a call request from the CPU or an incoming call request from one of the packet terminals is input to the CCP, if the B channel data link connection or the D channel data link connection for the packets has already been established between the CCP and the ISDN, the CCP selects the channel data link connection as a channel for communication with the packet terminal and multiplexes a plurality of calls to the same channel even if the other space B channels exist.

摘要： In a communication system having a plurality of host computers and two communication control processors (CCPs) connected to the respective host computers, one CCP is used as a regular CCP and the other CCP as a backup CCP. Each host computer establishes links with the two CCPs. Each of the host computers has a link flag for each link connected to each of the CCPs. The flag is set when the link is connected to the regular CCP. When the master host computer detects failure of the regular CCP, the master host computer sends an activate node request to the backup CCP to indicate that the backup CCP should be activated. Upon reception of the activate node request, the backup CCP sends a change output link request to all of the host computers. Upon reception of the change output link request, each of the host computers sets the link flag corresponding to the backup CCP to deal with the backup CCP as a regular CCP.

摘要： Herein disclosed is a communication network, in which two terminal nodes transmit and receive messages containing a destination node discriminator and a source node discriminator by way of a communication route composed of at least one relay node and a plurality of information links connecting the terminal nodes and the relay node. In this communication network, the relay node is stored in advance, in accordance with the combination of a destination node and a source node, with both the information link for transmitting the messages received and the flag information indicating the establishment of the communication route from said source node to the relay node itself. When any of the terminal nodes designates the other terminal node as the destination node and transmits the control message for the communication route establishment to the destination node, the relay node having received the control message sets the flag information, which corresponds to the combination of the source node and the destination node, in a state indicating the link establishment, and transmits said received message to said information link in case the information link corresponding to said combination is in the connected state. The relay node on the communication route transmits the control message to an adjacent node, when it detects the state change of the adjacent information link, under a condition that the flag information corresponding to said information link is in the set state.
摘要翻译：这里公开的是通信网络，其中两个终端节点通过由至少一个中继节点和连接终端节点的多个信息链路组成的通信路由发送和接收包含目的地节点鉴别器和源节点鉴别器的消息，以及中继节点。在该通信网络中，根据目的地节点和源节点的组合预先存储中继节点与用于发送接收的消息的信息链路和表示来自所述通信路由的标志信息源节点到中继节点本身。当任一终端节点指定另一终端节点作为目的地节点，并将用于通信路由建立的控制消息发送到目的地节点时，已经接收到控制消息的中继节点设置标志信息，其对应于源节点和目的地节点处于指示链路建立的状态，并且在对应于所述组合的信息链路处于连接状态的情况下将所述接收到的消息发送到所述信息链路。在与所述信息链路相对应的标志信息处于设置状态的条件下，当其检测到相邻信息链路的状态改变时，通信路由上的中继节点向相邻节点发送控制消息。
