1. The method of processing a data stream in a synchronous transfer mode (STM) comprising:
- extracting a plurality of payload signals having data from the data stream;
writing data of the payload signals into a random access memory (RAM);
separately recording address locations of the data of each of the plurality of payload signals;
directing the RAM to separately read the data of each single one of the payload signals; and
attaching a cell header to the data read from the controller to form ATM cells.

Abstract
A data stream is converted from a synchronous transfer mode (STM) to an asynchronous transfer mode (ATM) by extracting data of a number of payload signals from the data stream, writing data of the payload signal into a random access memory (RAM), separately recording address locations of the data of each of the payload signals in separate buffers, directing the RAM to separately read the data of the payload signals, and attaching a cell header to the data read from the RAM to form ATM cells.
