  • Method of establishing signaling rate for single-line digital subscriber link providing extended range ADSL service with auxiliary pots channel
    Patent number: 6539081
    Abstract: An autobaud mechanism is executed by transceivers coupled to opposite ends of a communication loop, such as an extended range SDSL loop, to resolve the maximum data rate that can be supported by the loop, using signal power and quality measurements to first estimate the length of the SDSL loop and thereafter iteratively adjust baud rate and/or number of bits/per baud, as necessary, to realize an SDSL baud rate that will ensure error-free transmission over the loop.
    Type: Grant
