Description: This attribute represents the total number of PLC codewords which failed post-decoding LDPC syndrome check.
What is docsIf31CmDsOfdmChanPlcUnreliableCodewords?
A 64-bit counter of PLC (PHY Link Channel) codewords the modem received on this downstream OFDM channel that failed the post-decoding LDPC syndrome check, i.e. codewords FEC could not correct. Because the PLC carries essential channel-configuration data, a rising count here is a strong signal of a plant or signal problem that could disrupt the modem's ability to stay synced on this OFDM channel, worth prioritizing over ordinary data-codeword errors.
