Abstract
A method of bit rate de-adaption between an adapted data rate and a user data rate using the ECMA 102 protocol. The user data is transmitted from a data adapter to a user terminal at a first data rate, the adapted data is received by the data adapter at a second data rate, and the second data rate is greater than the first data rate. The adapted data contains a start element and a plurality of data elements while the user data contains a start element and at least one stop element. The method involves the steps of: (1) Receiving the adapted data at the second data rate; (2) Converting the adapted data into a frame; (3) Storing the frame in a receiver buffer; (4) Dissecting the frame into an intermediate data; (5) extracting the plurality of data elements from the intermediate data; (6) Storing the plurality of data elements in a transmit buffer; (7) Converting the first plurality of data elements to the user data by adding the second start element and the at least one stop element; and (8) Transmitting the user data to the user terminal at the first data rate.
