Impulse noise management

Abstract

A discrete multitone transceiver (DMT) includes a deinterleaver operable to de-interleave a plurality of bits. The DMT further includes: a forward error correction decoder operable to decode the plurality of bits, a module operable to determine, during Showtime, an impulse noise protection value, wherein the impulse protection value specifies a number corrupted DMT symbols that can be corrected by the forward error correction decoder in combination with the deinterleaver, and a receiver coupled to the deinterleaver. The receiver receives using a first interleaver parameter value, receives a flag signal, and changes to receiving using a second interleaver parameter value that is different than the first interleaver parameter value, wherein the second interleaver parameter value is used for reception on a pre-defined forward error correction codeword boundary following reception of the flag signal.

1 . In a transceiver, a method of adapting the impulse noise protection capability during steady-state communication comprising:
 receiving using a first FIP setting; and   switching to receiving using a second FIP setting.
