A read-only WirelessGauge64 giving the cumulative sum of errored codewords received on this head-end channel since the link was last administratively brought up, tracked at 1-minute granularity. Paired with p2mpHe1MinTotalCodewords, it gives a minute-resolution channel-wide error rate, useful for spotting periods of degraded channel quality without the noise of second-by-second sampling. For example, graphing p2mpHe1MinErroredCodewords over a full day at the channel level might reveal a recurring window each afternoon when a specific external interference source affects every subscriber sharing that channel.
