bit rate adaption

Bit rate adaptation is an adaptive method for adapting line-oriented transmissions with different transmission rates.

Bit rate adaptation is used to adapt networks with different transmission rates to each other. Well-known examples are the standardized bit rate adaptation of the terminal adapter according to V.110 at the base channel of the ISDN connection or the adaptation of the modem parameters to the line characteristics according to V.22bis.

Bit rate adaptation is also used in various xDSL procedures, namely to compensate for interference. In DSL transmission, impairments in the transmission rate can occur on the sometimes older subscriber lines(local loops) due to crosstalk and near-end crosstalk. These impairments are compensated for with Dynamic Spectrum Management( DSM), which also provides bit rate adaptation to adjust the transmission rate to the technical limitations.
