ABSTRACT:
A method, for use in an asynchronous transfer mode (ATM), for effectively decoupling a cell transfer rate between a higher cell transfer rate segmentation and reassembly (SAR) layer and a lower cell transfer rate physical (PHY) layer in a universal test and operations PHY interface for ATM (UTOPIA) is provided. After processing scheduling for cell data based on a bandwidth assignment table of the SAR layer to produce scheduling information, valid cell information of the valid cells is detected from the scheduling information. In accordance with a cell control signal generated based on the valid cell information, idle cells are discarded and valid cells are transmitted to the PHY layer.
