Abstract: The invention relates to a method and a device for optimised xDSL data transmission. In a data connection with a maximum theoretical data transmission rate RTmax, the maximum currently available data transmission rate RAmax is determined by means of a training procedure between two modems. During the data transmission after a training phase (T), at least one modem determines the difference RDiff between the maximum theoretical data transmission rate for said connection and the maximum currently available data transmission rate RAmax from current measured SNR values and values derived therefrom for the maximum currently available data transmission rate RAmax and, in the case where a threshold value RDiffMax is exceeded, a new training procedure is invoked.

Abstract: The invention relates to a method and a device for ADSL data transmission, preferably according to the standard T1.413, or ITU G992.1, whereby on a line fault occurring, a training procedure is initiated to determine the highest possible data transmission rate and during an uninterrupted data transfer period following a training phase (T), a highest possible data transmission rate is set without carrying out a new training, by successive increases in the applied bitrate in at least one transmission band and monitoring of error counts.
