DMLOST(15:0) holds the global MLOST threshold (CLP0+1 cells) for the PM data collection in
downstream direction. A PM block with more than MLOST lost cells is considered severely
errored by the data collection algorithm. Accordingly the SECB counter is incremented. If less
or equal MLOST cells are missing the lost cell counters are incremented.

DMMISINS(15:0) holds the global MMISINS threshold for the PM data collection in downstream
direction. A PM block with more than MMISINS misinserted cells is considered severely errored
by the data collection algorithm. Accordingly the SECB counter is incremented. If less or equal
MMISINS cells are misinserted the misinserted cell counters are incremented.

DMLOST0(15:0) holds the global MLOST0 threshold (CLP0 cells only) for the PM data collection
in downstream direction. A PM block with more than MLOST0 lost cells is considered severely
errored by the data collection algorithm. Accordingly the SECB counter is incremented. If less
or equal MLOST0 cells are missing the lost cell counters are incremented.

DMERR(15:0) holds the global MERR threshold for the PM data collection in downstream
direction. A BR cell carrying a block error result BLER value greater than MERR denotes a
severely errored block. Accordingly the SECB counter is incremented. If BLER is less or equal
MERR the BLER value is added to the error counter ERRC.
