This read-only WirelessGauge64 reports the cumulative total received codewords detected since link power-up, as captured at the timestamp recorded in cwr1HrUpdateTime. It gives an admin the hourly-resolution total-volume figure needed to compute an hour-by-hour codeword error rate alongside cwr1HrErroredCodewords. For example, an admin building an hourly error-rate chart would divide each hour's cwr1HrErroredCodewords by that same hour's cwr1HrTotalCodewords.
