This read-only Counter tracks a running count of Ethernet frames the CPE successfully received on the CPE's Ethernet interface, tallied per hourly interval. Operationally, it is the basic throughput/health indicator for the customer's LAN hand-off, since a healthy port should keep incrementing this steadily under traffic. For example, an admin comparing this counter across two hourly buckets can tell whether the customer's Ethernet port was actually passing traffic during a reported outage window.
