Abstract:
1. A protection apparatus in a central office (CO) or a customer premise equipment (CPE) in an xDSL system for mitigating the effects of repetitive electrical impulse noise (REIN) and a single high impulse noise event (SHINE) within a physical layer and network processing layer, comprising: a forward error correction (FEC) module, wherein the FEC module comprises: a Reed-Solomon (RS) encoder-decoder; and an interleaver-deinterleaver; and a retransmission module configured to request retransmission of corrupted data fragments within the data stream not corrected by the FEC module, wherein retransmission is performed above a gamma interface of the xDSL system, the gamma interface being an interface above a transmission protocol layer.
