Abstract
A data transmission method and apparatus provides for transmitting lower data rate information in a higher data transmission rate environment. Information entities to be transmitted are broken into smaller entitles called nyblets. Higher data transmission rates are accomodated by accelerating a clock and clocking nyblets from memory at rate that allows the nyblets to be serially assembled into expected bit length words. Lower data rate information, which in conventional systems was transmitted redundantly to achieve compatibility with higher data rate systems, is now transmitted without duplication as a plurality of nyblets in series until the expected bit length is achieved. The result is that more information can be transmitted over a communication medium, since duplicate or redundant transmission of lower data rate information is avoided.
