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.

A fixed-length cell multiplexing/distributing processing is disclosed. The apparatus for this processing includes a plurality of fixed-length cell transmitting apparatuses, each of which sends a fixed-length cell, and a fixed-length cell multiplexing apparatus which multiplexes the fixed-length cells received from the fixed-length cell transmitting apparatuses and outputs the thus multiplexed cells. One of the plurality of fixed-length cell transmitting apparatuses is configured as a highest-priority fixed-length cell transmitting apparatus. Further, the highest-priority fixed-length cell transmitting apparatus comprises a fixed-length cell storage section and a fixed-length cell read control section. The fixed-length cell multiplexing apparatus comprises a plurality of FIFO storage sections, an FIFO control section, and a multiplexing section. With this structure, information to be notified is divided into fixed-length cells for transmission. The fixed-length cell from the highest-priority fixed-length cell transmitting apparatus is directly output without storing it, thereby accurately performing first-come, first-served processing for fixed-length cells.
摘要:
A data communication method enables communications between terminals adapted to handle frame structure data having different formats. The terminals are connected via an asynchronous transfer mode (ATM) network in which frame structure data is transmitted in a form of an ATM cell. The terminals include at least a first terminal and a second terminal. The first terminal is adapted to handle data having a super frame (SF) format. The second terminal is adapted to handle data having an extended super frame (ESF) format. A type of frame format of frame structure data to be sent to one of the terminals is distinguished by detecting a synchronization pattern of the frame structure data. The frame structure data is converted when the frame structure data is sent to the one of the terminals so that the converted frame structure data has a type of frame format corresponding to the detected synchronization pattern.

It is an object of the present invention to permit division of an LED wiring board into various sizes to permit its use before and after the division, and also simplify operation of this division and simplify circuit design. More specifically, in the present invention, wiring patterns and for energizing LEDs are formed in a planar direction of the LED wiring board. Division grooves for dividing the LED wiring board into a plurality of sub-boards are formed on the front surface of the LED wiring board in a perpendicular direction and are provided in a manner such as to cross the wiring patterns in the planar direction. Use with the entire board before the division by the division grooves is possible, and use with division elements divided along any of the division grooves is also possible.
