<p>A method for implementing the rate change of the data of Transmission Convergence layer in ADSL system. According to the number of the bits per symbol of Transmission Convergence configured by the system, determine the bit rate of the data transmission and further determine the other required configuration information, such as the number of the symbols corresponding to an FEC frame, the number of the bits comprised in an FEC frame practically, so that the data process is converted from the byte process for PMS-TC layer to the bit process for PMD layer, which enables the data with byte as a unit from PMS-TC layer to satisfy both the requires of the byte process for PMS layer and the bit rate increase in PMD layer in ADSL2 protocol and implements the 4K stepping of the data rate in ADSL system. There is also an apparatus implementing the above method.</p> |
