In both cases (COCUP=1 and COCUP=0), if a cell fails both GCRA1 and GCRA2, the most
severe action is taken on the cell.
The three 16-bit non-compliant counts are programmed in either the NCOUNTx[3:0] or the
GFR_NCOUNTx[3:0] fields of the Per-VC Non-Compliant Cell Counting Configuration,
depending on whether the GFR bit is set to logic 1 in the policing configuration field of the VC
table. Each non-compliant count has the following programming options:

The Total AAL5 Frames Received counts are available in non-GFR connections, but the other
frame-aware counts should not be selected except in the GFR case. Counting of CLP0 vs. CLP 1
frames is based on the CLP of the received EOP.
These non-compliant cell counts may, for instance, be programmed to satisfy the following
requirements:
