Apparatus and method for controlling cell multiplexing by priority in an ATM layer cell multiplexing unit

摘要

The present invention relates to an apparatus and method for transmitting data using a physical layer under a SDH (Synchronous Digital Hierarchy) environment in a Broadband Integrated Services Digital Network (B-ISDN)_B, Or T_BThe Asynchronous Transfer Mode (ATM) layer transmitter of the interface part provides up to four 53 octet service data cells and two 53 octets of service data cells provided by the upper ATM application layer and ATM layer control part And more particularly, to an apparatus and a method for controlling multiplexing of protocol data cells of a TET, and more particularly, to an apparatus and method for controlling multiplexing of protocol data cells of a TET, The present invention relates to an ATM layer cell multiplexer control apparatus and method for controlling cell multiplexing in a statistical manner in accordance with status information of input buffers and input buffers.;The present invention relates to an information input and status defining means 51 for receiving priority information of each input connection point provided from an ATM layer control unit and status information provided in each input buffer and selecting and providing priority data corresponding to each control mode ) And the selected priority data provided by the information input and status defining means 51 to control the output of each input buffer of the cell multiplexing unit 14 or the output of the idle / And a control signal generating means (52) for controlling the control signal.
