Per its DESCRIPTION, this Counter64 counts P-bit parity errors in the DS3 M-frame overhead, which reflect framing-bit mismatches typically attributable to the far-end signal. Because this counter is not split into rollover bins at all, a reading here means P-bit parity mismatches from the far end have accumulated on this DS3 circuit, accumulated since this table was last cleared rather than since the start of the last short interval. For example, a reading of 0 events in this bin on this DS3 circuit with the corresponding line-side Cvl staying flat would point the fault toward the far-end equipment rather than this local circuit.
