MULTIPLEX TRANSMITTER FOR MICRO-FRAME

摘要

A multiplex transmitter for loading micro-frames smaller than a standard ATM cell on the standard ATM cell in a multiplexing state. Input micro-frames are sequentially introduced to a distributing circuit (504) through an interface (503). The circuit (504) distributes the micro-frames by using input distribution information. The distribution information follows service conditions set for each connection or each micro-frame. A buffer is selected for a fetching circuit (506) in accordance with prefixed buffer selecting logic. A cell discarding and monitoring circuit (508) discards such micro-frames that exceed allowable cell discarding time of t2-1 to t2-m. A multiplex processing circuit (507) delivers a cell or vacant cell to a cell output circuit (511) in accordance with the cell output timing of the circuit (511).
