This counter tracks the total number of good frames received over the satellite interface, indexed by cdd564RxStatsIndex. As the satellite-side analog of the Ethernet good-frames counter, this is the baseline healthy-reception counter to compare against the various Rx error counters, like HDLC CRC errors or abort/octet errors, for that same demodulator index; a healthy link shows this counter dominating the total received-frame count. On a demodulator locked with a solid Eb/No, this counter should climb continuously in proportion to the symbol rate; a stall here despite a locked demodulator would point to a framing or flow ID issue downstream of the RF layer.
