CIRCUIT FOR MULTIPLEXING ASYNCHRONOUS TRANSFER MODE CELL FOR INTERLINKING NARROW BAND NETWORKS TO EACH OTHER

摘要

PURPOSE: The circuit for multiplexing an asynchronous transfer mode cell for interlinking narrow band networks to each other is provided to perform the function for controlling a user parameter by obtained connection information, and synchronize a user cell and a received IPC cell with the module clock from a clock generator, and thereby transmitting a cell to an asynchronous transfer mode switch. CONSTITUTION: An upper direction cell bus(11) receives the user cell by a word size. A cell bus buffer(12) removes an external noise. A cell bus controller(13) checks if the transmission of the cell is requested, and efficiently transmits the cell. A content address memory(14) is accessed when the connector for the header of a received user cell is generated. A cell controller(15) is connected to the controller(13) and the memory(14). A FIFO memory(21) receives the signals from the controller(15). A memory(22) stores control data and statistical data. A processor(23) controls a traffic parameter. A FIFO memory(31) stores the user cell passed via the processor(23). A head conversion table(35) is connected to a header transfer and cell integrated circuit(34).
