摘要： In a telephone switching apparatus having an inter-office interface consisting of a plurality of communication circuits having different priorities and a control line for transfer of call control signals, a first circuit having the highest priority is hunted from the idle one of said communication circuits upon setting of a call and the communication is started. During the communication, if a second circuit having a higher priority than that of the first circuit becomes idle, by communicating a control signal to switch the circuit between the switching apparatuses, the busy circuit for the call is switched from the first circuit of a low priority to the second circuit of a high priority.

摘要： A multimedia information exchanging system in a digital exchange network that has an exchange system in which channels are selectively assigned for communication among a plurality of subscribers. This system has many pieces of subscriber line terminating equipment each of which is provided on the subscriber side of each subscriber line and which connects at least one terminal device to the subscriber line through subchannels. The system permits simultaneous multiple communications between multiple pairs of terminal devices by sending request information from a first piece of subscriber line terminating equipment to a second piece of subscriber line terminating equipment--the request information calling for at least one of the subchannels available for use in a channel established between the two pieces of subcriber line terminating equipment--and by connecting the subchannels conforming to the request to one of the terminal devices accommodated in each of the first and second pieces of subscriber line terminating equipment.

摘要： A method and system for arranging a common channel signal through an ISDN in a switching network. In the switching network, a signal is transferred between the switching stations in a common channel signalling manner. This method and system serves to allocate a signal path between the stations through the ISDN without having to provide a dedicated channel between the stations as a common channel signal path. Then, the method and system establishes a temporary connection between the stations through the ISDN using a channel in the ISDN (for example, D channel) used for controlling the call setup between the ISDN and a terminal and transfers a common channel signal between the stations by transferring transparent user information to the ISDN. In the common channel signal network in which a common channel signal is transferred through a leased line, the signal transfer is switched from the leased line to the ISDN when failure takes place in the common channel signal path.

摘要： A switching system is provided in which when a calling subscriber has transmitted an identification (ID) number of a called subscriber and an ID number of the calling subscriber from a calling terminal to a switching equipment having a subscriber control table at the time of making a call, the switching equipment receives the ID numbers and connects the calling terminal with the called terminal. In response to an input of an ID number of a called subscriber and an ID number of a calling subscriber by the calling subscriber to a terminal at the time of making a call, the switching equipment changes a registration state corresponding to the ID number of the calling subscriber in the subscriber control table from an idle state to a busy state, manages the idle and busy states of the subscriber himself or herself corresponding to the ID number, retrieves the subscriber control table in response to a reception of a call signal which designates an ID number of a called signal from a calling subscriber, and forwards the call to a default terminal which has been registered in advance by the called subscriber having the ID number, when the terminal corresponding to the called subscriber having the ID number is busy and the called subscriber having the ID number himself or herself is not busy as a result of the retrieval of the subscriber control table.

摘要： The communication system has a plurality of sub-networks, for example composed of transmission communication nodes, PBX communication notes, application communication nodes, and the like, respectively. Each of these sub-networks is managed by a management system, and all of the management systems are managed by an integrated management system. Each communication node is autonomously provided with the function of establishing an emergency routing as a first stage routing control on the occurrence of a failure in a circuit affecting the communication node. The autonomous routing is heirarchial with respect to node types. Failure and the influences of failure are reported to the sub-network management systems, which in turn can report to the integrated management system. As a second stage of routing control, one or more of the management systems establishes a global routing to replace the emergency local routing. The global routing may take effect if the managment system determines that the failure cannot be corrected within a substantially fixed period of time.
