摘要： In a duplicate active-standby memory unit arrangement, a resynchronization initiation determination is made on a cell-interval-by-cell-interval basis based on the equality of cell contents of corresponding queues in the active and standby memory units. If an inequality of the cell contents of the corresponding queues in the active and standby memory units occurs during any cell interval, resynchronization may be initiated. In an exemplary embodiment of the invention, the lengths of data in corresponding queues, i.e., the number of cells stored in the corresponding queues, in the active and standby memory units are compared on a cell-interval-by-cell-interval basis. If the number of cells stored in any of the queues is different than the number of cells its corresponding queue in the other of the memory units during any cell interval, resynchronization of the memory units is initiated. In another embodiment of the invention, the outputs of corresponding queues in the active memory unit and the standby memory unit are compared on a cell-interval-by-cell-interval basis. If the results of the comparison indicates that any one or more of the queue outputs in one of the memory units is different from the output of the corresponding queue in the other memory unit, resynchronization is initiated. Robustness of the latter comparison algorithm is enchanced by restricting the comparisons to cell intervals during which the queue outputs in the active and standby memory units do not both include idle cells. Additionally, robustness of the resynchronization initiation is further enhanced by simultaneously employing both the comparison of cell length in the queues and the comparison of the queue output contents to detect when to initiate resynchronization.
摘要翻译：在重复的活动备用存储器单元布置中，基于活动和备用存储器单元中相应队列的单元内容的相等性，以单元间隔间隔为单位进行重新同步启动确定。如果活动和备用存储器单元中的相应队列的单元格内容的不等式在任何单元间隔期间发生，则可以启动重新同步。在本发明的一个示例性实施例中，在单元间隔间隔的基础上比较在对应队列中的数据长度，即存储在相应队列中的活动和备用存储单元中的单元的数量。如果任何队列中存储的单元的数量不同于在任何单元间隔期间的另一个存储器单元中其相应队列的单元数量，则启动存储器单元的再同步。在本发明的另一个实施例中，在单元间隔间隔的基础上比较有源存储器单元和备用存储器单元中相应队列的输出。如果比较结果表明存储单元之一中的任何一个或多个队列输出与其他存储器单元中的对应队列的输出不同，则重新同步被启动。通过将活动和备用存储器单元中的队列输出不包括空闲单元的单元间隔进行比较来限制后者比较算法的鲁棒性。此外，通过同时使用队列中的单元长度的比较和队列输出内容的比较来检测何时启动重新同步来进一步增强再同步启动的鲁棒性。

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： In a test method and apparatus for testing a virtual path in an asynchronous transfer mode system, a sequence number is included in an operation administrating monitoring (OAM) cell to specify the OAM cell for testing a virtual path between transmission and reception sides. The sequence number is inserted into the OAM cell by the use of an idle cell and is received by a sequence number test circuit included in the reception side. The sequence number in the OAM is collated with a result of counting the OAM cell in the reception side to detect coincidence or non-coincidence between the sequence number and the result of counting. On detecting the non-coincidence, a loss of the OAM cell or wrong reception of the OAM cell is detected on the reception side. Otherwise normal operation is confirmed between the transmission and the reception sides.

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： Virtual path operation information of each of the stations of an synchronous transfer mode telecommunications network is traced using OAM cells. OAM cells used for operation and maintenance control of the asynchronous transfer mode telecommunication network have a pointer indicative of the position where virtual path operation information is recorded and an area for storing virtual path operation information of a certain number of stations. Each station records virtual path operation information in an OAM cell, updates the pointer and sends the OAM cell to the next station on a selected path. When the payload of the OAM cell becomes full, the OAM cell records new OAM cell generation request information and the pointer is changed to the final value and is sent to the next station. A station which receives the OAM cell erases the new OAM cell generation request information, transfers the received OAM cell, generates a new OAM cell, initializes the pointer, and transfers the new OAM cell which has its own virtual path operation information to a next station.

摘要： An optical access network method, an optical access network and an optical switch for an optical access network, capable of solving all the three problems in the conventional GE-PON: transmission distance problem, security problem and communication interference problem. The optical access network comprises an OLT, a plurality of ONUs and one or more stages of optical switches, which are connected one another. In the direction from the OLT to the ONU, each frame (packet) transmitted from the OLT to one of the ONUs is checked so that only the destination ONU specified in the frame (packet) is connected to the OLT. In the direction from the ONU to the OLT, a control message transmitted from the OLT to one of the ONUs is checked so that only one ONU which has been given a transmission allowance from the OLT is connected to the OLT with respect to each frame (packet).

A central unit (OLT) transmits a DC-balanced optical continuous signal including packets having identification information for identifying each remote unit (ONU) to an optical switching module (OSM). The optical switching module (OSM) receives the DC-balanced optical continuous signal from the central unit (OLT), optically switches the packets based on the identification information, and transmits a DC-balanced optical burst signal including the packets to the remote unit (ONU). The remote unit (ONU) receives the DC-balanced optical burst signal and acquires the packets transmitted to the remote unit (ONU).
