A read-only WirelessGauge64 giving the cumulative count of errored codewords received by this radio link since it was last administratively brought up, current as of this operational hour. It is the hourly-resolution numerator counterpart to p2mpSu1HrTotalCodewords, well suited for spotting which specific hours of the day tend to have the worst error accumulation. For example, plotting p2mpSu1HrTotalErrCodewords hour by hour across a week might reveal errors consistently spiking during a specific time of day tied to a recurring source of interference.
