A read-only Unsigned32 giving the total number of errored codewords transmitted by this specific subscriber unit during the current operational hour. It is the raw count backing the p2mpPctErroredCodewords percentage, and together they let an admin see both the absolute scale and the relative severity of this unit's current-hour errors. For example, a p2mpTotalErroredCodewords value that is high in absolute terms but represents a small percentage of a very high-traffic hour might be less concerning than a smaller absolute count representing a much larger share of a low-traffic hour.
