  • Receiver-side selection of DSL communications mode
    Patent number: 7555049
    Abstract: A client premises digital subscriber line (DSL) modem having multi-mode capability is disclosed. In initialization, the modem estimates whether channel conditions are such that digital processing of the received data according to a lower data rate DSL standard, such as ADSL2, may result in a higher effective data rate than receipt and processing according to a higher data rate DSL standard, such as ADSL2+. If so, the DSL modem configures itself, such as by configuring its filter characteristics and sampling frequency, to receive and process data according to the lower data rate DSL standard; the transmitting modem, for example at a central office or service area interface, may continue to operate according to the higher data rate standard (with its bit loading corresponding to a subset of subchannels). The receiving DSL modem processes the payload data according to the lower standard, while processing control messages according to the higher standard.
