Abstract:
1. A method for communicating data, comprising: defining a data transmission unit (DTU) to be sent in an xDSL data stream; defining a retransmit container as a time slot that corresponds to a sent DTU; maintaining a copy of the sent DTUs and an index of corresponding retransmit containers in retransmission buffer; transmitting the DTUs in the xDSL data stream; determining whether a transmitted DTU should be retransmitted; identifying each corrupted DTU by its corresponding retransmit container; and retransmitting an uncorrupted copy of the DTU as identified by the corresponding retransmit container, wherein the retransmission is deferred until the DTU is at a predefined position in the retransmission buffer.
