Abstract
A method and apparatus for buffering data samples in a software-based ADSL modem. The method includes generating data for transmission to a remote source and modulating the data to form a plurality of data symbols for transmission. The data symbols are stored in a buffer. An absence of a data symbol in the buffer is determined. In response to detecting an absence of a data symbol in the buffer, an idle data symbol is transmitted.
