With the current initialization procedures defined in the VDSL and ADSL standards even though the xDSL system could operate in Showtime in an impulse noise environment where symbols are being corrupted the transceivers would not be able to reach Showtime because initialization would fail due to initialization message failure. Through the use of an improved initialization procedure for communication systems operation in environments with higher levels of impulse noise is possible.
