Abstract

See full text

A method for selection of a digital subscriber line (DSL) technology for use by a first DSL transceiver in transferring data over a communications line between the first DSL transceiver and a second DSL transceiver. For the selection, an indication of attenuation in the communications line between the DSL transceivers is obtained and a DSL technology for use by the first DSL transceiver is selected from a plurality of DSL technologies supported by the first DSL transceiver. Selection of the DSL technology is determined on the basis of the indication of attenuation. Optionally, selection of the DSL technology may, in addition, be based on other parameters comprising an indication of the power spectral density mask limiting the power output onto the line by the DSL transceiver; an indication of the noise environment of the communications line; an indication of the highest discrete multitone modulation tone transmitted by the first DSL transceiver over the communications line.
