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： 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： An optical network unit and an optical line terminal which efficiently control the data receiving and dechurning processes in a passive optical network. In a churning parameter memory subsystem, a first memory bank stores churning parameters that are currently used, while a second memory bank stores updates made to the churning parameters. Under the control of the churning parameter memory subsystem, those first and second memory banks change their roles with each other at a churning key updating time point. A data dechurning unit receives a data stream consisting of a plurality of frames and dechurns the information contained in the data stream, according to the stored churning parameters. When an update is done to the parameters in a certain frame, the data dechurning unit makes the update effective at the next frame, thus starting data dechurning operations from the next frame.

摘要： In an ATM cell multiplexer which multiplexes ATM cells outputted from a plurality of cards, sequential cell arrival numbers common to the ATM cells outputted from a plurality of cards are added to each of the cells to be written in memories, and the read side checks a sequentiality of the cell arrival numbers whereby the ATM cells are read in the order of arrival and the cell arrival number at that time is used as the cell arrival number to be checked at the next read time. Also, when any of the cards is pulled out, a card not pulled out is operated normally and an address counter of only the pulled-out card is cleared. Even when non-sequentiality of the cell arrival numbers occurs due to the clearance of the address counter, the maximum cell arrival number is set to the value which enables the oldest cells to be read first. Furthermore, by the division of storing memories according to priority degrees, a read control identifying the ATM cells for a real time system as well as the ATM cells for a data system can be performed.
