A read-only WirelessGauge64 giving the cumulative count of codewords received on the head end from the subscriber unit identified by p2mpSuMacAddress, since that link was last administratively brought up, current as of this operational hour. Because this is measured at the head end for a specific named subscriber unit, it lets the head end track per-subscriber link quality on a shared point-to-multipoint channel rather than only aggregate channel statistics. For example, on a head end serving a dozen subscriber units over the same channel, comparing each unit's p2mpTotalCodewords lets the admin see which specific remote sites are carrying the heaviest traffic load.
