These registers define the thresholds in the PM data collection algorithm described in
ILJXUH
26.
The referenced counters are located in the PM Data Collection RAM (see
VHFWLRQ
3.9.6).

UMLOST(15:0) holds the global MLOST threshold (CLP0+1 cells) for the PM data collection in
upstream 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.

UMISINS(15:0) holds the global MMISINS threshold for the PM data collection in upstream
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.

UMLOST0(15:0) holds the global MLOST0 threshold (CLP0 cells only) for the PM data collection
in upstream 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.

UMERR(15:0) holds the global MERR threshold for the PM data collection in upstream 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.
