Misinserted Cell Count - The Misinserted Cell Count is incremented by the
number of misinserted cells if the number of received cells in the block is more
than the number that are expected based of the contents of the TUC field. If the
number of misinserted cells equals or exceeds the threshold set by the
MMISINSERT[7:0] register bits, the SECB count is incremented and the
misinserted cell accumulation is suppressed.
BIP-16 Violation (BIPV) Count - The BIPV count is incremented by the number
of mismatches between the locally calculated BIP-16 code and the value
encoded in the BIP-16 field. If either of the MSN or the TUC values are incorrect,
the BIPV accumulation is suppressed. If the number of BIPV errors equals or
exceeds the threshold set by the MERRORED[4:0] register bits, the SECB count
is incremented and the BIPV accumulation is suppressed.
Severely Errored Cell Block (SECB) Count - This parameter is incremented if
the number of BIPVs, lost cells or misinserted cells are equal to or greater than
the threshold set by the MERRORED[4:0], MLOST[7:0] and MMISINSERT[7:0]
register bits, respectively.
The RCMP-200 also maintains the analogous counts for the reverse flow at
SA[19:16]=1110. These counts are updated upon the reception of either a
Backward Reporting cell or a Monitoring/Reporting cell. The MERRORED[4:0],
MLOST[7:0] and MMISINSERT[7:0] register bits also set the SECB thresholds
for the reverse flow.
The count values contained in the SA[19:16]=1110 and 1111 locations are
cleared to zero upon a microprocessor read access.
9.3.9 Activation/Deactivation Cells
Activation/Deactivation cells are identified with a OAM Cell Type of 1000. They
are used by the management entity to implement the handshaking required to
initiate or cease performance monitoring or continuity check processes.
The RCMP-200 does not process these cells. If the RCMP-200 is not an end
point for an OAM cell flow, all Activation/Deactivation cells are passed to the
Output Cell Interface. If the RCMP-200 is an end point for a OAM flow, the
Activation/Deactivation cells are optionally passed to the Microprocessor Cell
Interface or the Output Cell Interface. The flow of the Activation/Deactivation
cells is controlled by the ACTDEtoUP and ACTDEtoOCIF bits of the ALCP
Routing Configuration register. This enables the management entity to process
