Abstract
Methods and apparatus for transmitting and receiving data using framing circuitry designed to generate data frames of a first duration at a first data rate. According to the invention, data frames are generated and decomposed at lower data rates than the rate for which the framing circuitry was originally designed, i.e., the first data rate. The framing circuitry is programmed to organize a data stream into a sequence of data frames of the first duration or to decompose such data frames into a data stream. According to the invention, such a sequence of data frames corresponds to a selected one of a plurality of equivalent data rates. Each of the equivalent data rates are lower than the first data rate.
