Abstract
A method for charging the data rate over an interleaved latency path overcomes shortfalls of the ADSL2 seamless rate adaptation (SRA) and dynamic rate repartitioning (DRR). The interleaver depth is allowed to change during either a rate charge or rate repartioning so that the interleaver delay is constant before and after the change. The transmitter pauses its transmission for a time approximately equal to the delay of the interleaver so that there are approximately no errors introduced at the receiver.
Claims17
A method for data transmission rate change for a digital subscriber line (DSL) transmission, comprising:
- changing an interleaver depth on an interleaved data path during the DSL transmission of data.
A method for a data rate change over a digital subscriber line (DSL), comprising:
- changing an interleaver length (l) on an interleaved data path on the DSL line
