摘要： An abnormality in operation is detected by meticulously monitoring the operation of a monitored device that comprises a state machine. The state number, indicating the state the monitored device is currently in, is output from the device. The upper and lower limit values of current consumption is set for each state number. A monitoring circuit, using the upper and lower limit values for the present state number, judges the value of current consumption detected by a current detection circuit and detects whether there is abnormality in operation.

摘要： If wavelengths λa and λb are dropped in NE (Network Equipment) 2 and a wavelength λc is made Through, and all of wavelengths are made Through in NE3 in a certain time period, a route from NE1 to NE2, a route from NE2 to NE4, and a route from NE1 to NE4 are established. If a user who uses the wavelength λa from NE1 to NE2, and a user who uses the wavelength λb from NE2 to NE4 do not use the routes in another time period, and if another user desires to use a route from NE1 to NE3 and a route from NE3 to NE4, the routes are reestablished in a way such that the wavelength λa is converted into the wavelength λb and made Through in NE2, and the wavelength λb is dropped and added in NE3.

摘要： An optical transmission technique for a ring transmission system that can transmit time-division-multiplexed optical signals in dual directions. An optical transmitting apparatus comprises a data link reading section, a topology creating section, a data link writing section, a squelch table creating section, a squelch table, an RIP table creating section, an RIP table, a node recognizing section, an east-side receiving unit, an east-side transmitting unit, a west-side transmitting unit, and a west-side receiving unit. When a transmission route is switched at plural positions, the squelch table and the RIP table are automatically created as soon as a crossconnect is set. With minimum setting, the ring transmission system can be normally operated without increasing the number of setting items, the squelch table can be created at a high speed using existing hardware, and an alarm can be automatically transmitted from a secondary node until each table is created.

摘要： In a monitoring device and system, a monitoring data inserter inserts monitoring data of a predetermined pattern into an idle period of input data to be transmitted to a transmission line. A monitoring data checker having received the monitoring data through the transmission line, when determining that the monitoring data does not maintain the predetermined pattern, provides selective switchover instructions to a selector to be controlled. Then, the monitoring data checker sequentially performs a selective switchover to processors, thereby detecting a failure point in the processors. Also, when the failure point in the processors can not be detected, the monitoring data checker provides channel switchover instructions to a switching portion and performs a channel switchover of the transmission line, thereby detecting which channel of the transmission line has caused a failure.

摘要： A dynamic memory management method and apparatus wherein an area of a memory is partitioned into a plurality of areas to form memory banks. The different priority classes share the memory banks. A policer (write controller) dynamically assigns input frame data of a plurality of classes having different degrees of priority to memory banks in accordance with the degrees of priority and stores the data there for each priority class. A scheduler (read controller) sequentially reads out the data from the frame data stored in the memory bank assigned to the class having the highest degree of priority and transmits the same. For storage of frame data of a priority of class input in a burst like manner, a plurality of memory banks are assigned to that priority class so as to raise the burst tolerance. By controlling writing and reading of data in units of memory banks, the control can be simplified. Due to this, the efficiency of usage of memory is improved and the write/read control is simplified.
摘要翻译：一种动态存储器管理方法和装置，其中存储器的区域被分割成多个区域以形成存储体。不同的优先级类共享内存。策略器（写入控制器）根据优先级动态地将具有不同优先权级别的多个类别的输入帧数据分配给存储体，并存储每个优先级类别的数据。调度器（读取控制器）从分配给具有最高优先级的类的存储体中存储的帧数据顺序地读出数据，并发送。为了以类似突发的方式存储类输入的优先级的帧数据，将多个存储体分配给该优先级，以提高突发公差。通过控制以存储体为单位的数据写入和读取，可以简化控制。由此，提高了存储器的使用效率，简化了写/读控制。
