Description: This attribute represents the count of codewords received that failed the pre-decoding syndrome check, but passed the post-decoding syndrome check from the CM on this Profile/Data IUC for this upstream OFDMA channel.
Discontinuities in the value of this counter can occur at re-initialization of the managed system, and at other times as indicated by the value of ifCounterDiscontinuityTime for the associated upstream OFDMA channel.
What is docsIf31CmtsCmUsOfdmaProfileCorrectedCodewords?
A 64-bit counter of codewords from this modem that initially failed the pre-decoding FEC syndrome check but were successfully corrected by forward error correction (passed the post-decoding check) on this upstream OFDMA profile. A rising corrected-codeword rate relative to total codewords is an early warning sign of a marginal upstream signal before it escalates to uncorrectable errors; resets can occur at system reinitialization.
