摘要： A packet directional path identifier transfer system contains on the transmission side thereof, a means 2 of converting packet directional path identifier data into bit map information in which an address of each bit corresponds to a packet directional path identifier. 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. (FIGS. 1 and 2.)

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： 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.

摘要： A coded transmission system wherein each bit of transmitted data having a logical value is coded depending on a coded result of a preceding bit. The coded transmission system contains a sender-side apparatus, a transmission line, and a receiver-side apparatus. In the sender-side apparatus, a resetting bit and a message are generated; a code of a bit last transmitted which is necessary to code a bit which is to be transmitted next is memorized in a first preceding code memorizing circuit; and the content of the first preceding code memorizing circuit is reset to an initial code responding to the resetting bit. A coding circuit receives the resetting bit and the message, codes each bit of the message in accordance with a predetermined coding rule and the content of the first preceding code memorizing circuit, and codes the resetting bit to a predetermined resetting code which is different from the codes used in the coding of the message. In the receiver-side apparatus, a code of a bit last received which is necessary to decode a code of a bit which is received next is memorized in a second preceding code memorizing circuit. A resetting circuit resets a content of a second preceding code memorizing circuit to a predetermined initial code when receiving the resetting code. A decoding circuit decodes the received codes corresponding to the message in accordance with the predetermined coding rule and the content of the second preceding code memorizing circuit.

摘要： A communication system including a master station, a plurality of slave stations each for communicating with the master station, a two-way transmission line connecting the master station and the plurality of slave stations. Each of the slave stations sends a request for further communication with the master station, to the master station when its own slave station is allowed to communicate with the master station and its own slave station has the above request. The master station detects the request for further communication with the master station in a signal sent from a slave station, and memorizes the slave station from which the request for further communication with the master station is detected, until an allowance signal is sent to the slave station from the master station corresponding to the memorizing of the slave station. The master station has a cyclic address pointer which points to an address of a next one of the slave stations in a cyclic order when no slave station is memorized in the master station. The master station outputs the allowance signal to communicate with the master station to a slave station which is memorized in the master station or to a slave station the address of which is pointed to by the cyclic address pointer when no request is memorized in the master station.

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： Disclosed is a communication network management system for converting action parameters contained in abstract requirements (abstract policy information) regarding a network to parameters conforming to the network technology (ATM, SDH, WDM, etc.) and type of network element to be set, and setting these parameters in the element. Specifically, a policy administration portion converts action parameters contained in abstract policy information to parameters dependent upon network technology and a policy enforcement portion converts the parameters obtained by this conversion to parameters dependent upon type of network element to be set and sets these parameters in the element.
