A METHOD OF BIT RATE ADAPTION USING THE ECMA 102 PROTOCOL

摘要

A METHOD OF IMPLEMENTING ECMA 102 RATE ADAPTION There is disclosed a method of adapting user data to rate adapted data using the ECMA-102 standard. The user data is received from a user terminal at a user data rate, the rate adapted data is transmitted at a adapted data rate, and the adapted data rate is greater than the user data rate. The user data is either in a asynchronous or a synchronous format and contains a start element and at least one stop element. The method involves the steps of: (1) converting the user data into an intermediate data; (2) storing the intermediate data in a receive buffer; (3) if the user data is in an asynchronous data format, adding stop elements to the intermediate data; (4) transferring the intermediate data in the receive buffer to a intermediate buffer; (5) constructing a frame using data from the intermediate buffer; (6) storing the frame in a transmit buffer, and; (7) transmitting the frame where the step of transmitting changes the frame into the rate adapted data.
