Latest Patents

One of Ando's latest patents is a "Multiplexer and priority control method for packet data transmissions." This invention allows for equal opportunities to transmit ATM cells of identical levels onto an ATM line from respective terminal side lines. In this system, data from terminal side lines is converted into ATM cells, which are then assigned priority levels. The priority controller selects the ATM cells of the highest priority levels from internal buffers corresponding to the terminal side lines. It further determines which ATM cell to transmit based on the priority sequence of these buffers. This innovative approach ensures that the priority sequence is updated each time an ATM cell is selected for transmission.

Another significant patent is the "Multiplexing apparatus," which reduces the circuit size of multiplexing devices. In this design, data from a terminal is received by terminal-side line interface sub-units and then processed by a cell assembly/disassembly sub-unit. The cells are transmitted directly to a priority control unit, where they are stored in priority control buffers and sent to an ATM network interface unit in order of priority. This design eliminates the need for an internal bus, streamlining the process of data transmission.
