The system contains on the reception side thereof, a means 5 for inversely converting the bit map information of the packet directional path identifier data to the packet directional path identifier data. Otherwise, the system further contains on the transmission side thereof, means 8 and 10 for determining the top and bottom values of the packet directional path identifier data to be transmitted, and a means 9 for converting the packet directional path identifier data between the top and bottom values into bit map information, and at the reception side thereof, a means 13 for inversely converting into the initial packet directional path identifier data the bit map information of the packet directional path identifier between the top and bottom values. Further, the top value of the identifier(s) of the newly-set packet directional path(s) determined from the non-used packet directional path identifier(s) in the outgoing packet directional path of the transmission-side node and the number of the newly-set packet directional path identifier(s) are transmitted, and a reference is made to the incoming packet directional path identifier table at the reception-side node to recognize the newly-set packet directional path(s) based on the information received.

    摘要: In an ATM switching network, ATM (asynchronous transfer mode) self-routing switches are interconnected by facilities carrying STM-N (synchronous transport modules level N) signals. At each inlet of an ATM self-routing switch, an STM overhead is removed from each frame of an incoming STM-N signal to create a vacant interval and the frame is converted according to ATM cell format into a series of data ATM cells, and an idle ATM cell is derived from the vacant interval. A supervisory bit sequence is inserted to the payload field of the idle ATM cell to produce a supervisory ATM cell, and the data and supervisory ATM cells are sent into the ATM switch. At each outlet of the switch, the bit sequence of the supervisory ATM cell is checked to evaluate the quality of the ATM switch and a series of data ATM cells is then converted into an STM-N signal according to STM-N frame format.

    摘要: An alarm masking system is provided which is capable of implementing alarm priority processing or alarm inhibit processing in ATM transmission equipment. In ATM transmission equipment, a received virtual path or virtual channel is switched by means of a switching unit and then sent to an interface unit. In doing this, if a higher priority alarm is detected or received at a reception side interface unit, an intra-office tag is added to the alarm cell and then it is output, so that by detecting this intra-office tag it is possible to inhibit generation of lower priority alarms in response to the higher order alarm.

    摘要: An inter-network connecting system comprising a main network having an exchange function and a subnetwork having no exchange function, to improve the expandability, economy, and efficiency of the subnetwork. When an extension line communication which is a communication in the subnetwork is to be carried out, a call setting processing processor in the main network gives a calling terminal a first special signal so as to operate lookback means in a connection control unit in the subnetwork to set a physical communication paths for an extension line between terminals in the subnetwork; and when an outer line communication which is a communication between the main network and a terminal in the subnetwork is to be carried out, the call setting processing processor gives a calling terminal a second signal so as to stop the operation of the loopback means in the connection control unit to set a physical communication path for an outer line between the exchange and the terminal in the subnetwork.

    摘要: A communication system containing a master station and a plurality of slave stations. The master station receives a request from one of the plurality of slave stations and memorizes one or more requests from one or more slave stations. The master station also sends a request sending allowance signal which addresses one of the plurality of slave stations to give an allowance to send a request for sending data, and sends a data sending allowance signal which addresses one of the plurality of slave stations to give an allowance to send data, according to a request which is memorized. Each of the slave stations detects a request sending allowance signal which addresses its own slave station, and a data sending allowance signal which addresses its own slave station. Each of the slave stations also sends a request for sending data to the master station when its own slave station detects a request sending allowance signal which addresses its own slave station. In addition, each slave station sends data to the master station when its own slave station detects a data sending allowance signal which addresses its own slave station.
