Method for communicating data in xDSL using data retransmission
First Claim
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.

Abstract
A method for transmitting data in an xDSL system is disclosed. In an exemplary embodiment, the method includes 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. The retransmission is deferred until the DTU is at a predefined position in the retransmission buffer.
