摘要： System for controlling access competition among a plurality of terminals under the DQDB protocol in a B-ISDN where the terminals are electrically connected to a dual bus with a downbus and an upbus extending from a network terminal. Each of the terminals has data transmission processor, downbus processor, upbus processor, a timer and failure detector. When data transmission request is issued from the data transmission processor, the failure detector is activated in response to a request to start the timer so as to count a given time interval which has elapsed. If either a request message or data cannot be sent even when the timer reaches a predetermined value, the failure detects signals that a failure has occurred in the dual bus.

摘要： A telemetry supervisory system in an asynchronous transmission mode network which discriminates less information when less variation rates occur and more information when more variation rates occur, and provides a transmission system for transmitting the discriminated information as a cell having a fixed length, includes an object detecting and monitoring device, a coder for coding picture signals from the detecting and monitoring device, a transmission unit which changes the output of the coder into cells each having a fixed length and a monitor station. Monitoring information such as a picture image or sound from a monitored object is transmitted by the transmission unit for a discrimination of the information. A number of cells transmitted as data is monitored at the receiving side, e.g. monitor station, and a variation of the number of cells is treated as a change in the state of the monitored object.

摘要： A method of connection of a priority call in a wireless communication system able to assign channels making full utilization of system resources and to thereby prevent failure of connection (call loss) of an emergency call or other priority call, which sets a maximum threshold Th.III between a critical threshold Th.IV constituting an upper limit, in terms of hardware, on the number of calls able to be assigned channels in a wireless section, and a design threshold Th.II constituting an upper limit, in terms of software design. It assigns a priority call a channel and connects the call to the exchange side even if the total number of calls exceeds the design threshold Th.II, but if it determines that it is smaller than the maximum threshold Th.III, performs breathing when the total number of calls exceeds the design threshold Th.II, and sends a standby instruction message to the terminal side when it determines that the total number of calls has exceeded the maximum threshold Th.III.

摘要： Information selectively read out from an information source storing various types of information is repeatedly sent from a center office to a number of terminal equipment units with an error check code added on. The terminal equipment units use the error check code to detect if there is an error in the received information. If the information is received without error, the reception operation is ended for each terminal equipment unit. In this case, there is no interposition of a protocol for confirming if the transmission and reception of the information had been performed normally, so the load on the center office is lightened and it is possible for each of the terminal equipment units to receive the information without error.
