Performance Monitoring Parameter Definitions
CVP-P Code Violation Path (CVP-P) is a code violation parameter for M23
applications. CVP-P is a count of P-bit parity errors occurring in the
accumulation period.
DCG Date Code Groups (DCG) is a count of received data code groups that do
not contain ordered sets.
EB Path Errored Block (EB) indicates that one or more bits are in error within
a block.
ES Path Errored Second (ES) is a one-second period with one or more errored
blocks or at least one defect.
ESCP-P Errored Second Path (ESCP-P) is a count of seconds containing one or
more CP-bit parity errors, one or more severely errored framing (SEF)
defects, or one or more AIS defects. ESCP-P is defined for the C-bit parity
application.
ESCP-PFE Far-End Errored Second CP-bit Path (ESCP-PFE) is a count of one-second
intervals containing one or more M-frames with the three FEBE bits not all
collectively set to 1 or one or more far-end SEF/AIS defects.
MS-ES Errored Seconds Line (ES-L) is a count of the seconds containing one or
more anomalies (BPV + EXZ) and/or defects (loss of signal) on the line.
ES-P Path Errored Second (ES-P) is a one-second period with at least one defect.
ES-PM Path Monitoring Errored Seconds (ES-PM) indicates the errored seconds
recorded in the OTN path during the PM time interval.
ESP-P Errored Second Path (ESP-P) is a count of seconds containing one or more
P-bit parity errors, one or more SEF defects, or one or more AIS defects.
ESR Path Errored Second Ratio (ESR) is the ratio of errored seconds to total
seconds in available time during a fixed measurement interval.
ESR-P Path Errored Second Ratio (ESR-P) is the ratio of errored seconds to total
seconds in available time during a fixed measurement interval.
ESR-PM Path Monitoring Errored Seconds Ratio (ESR-PM) indicates the errored
seconds ratio recorded in the OTN path during the PM time interval.
ESR-SM Section Monitoring Errored Seconds Ratio (ESR-SM) indicates the errored
seconds ratio recorded in the OTN section during the PM time interval.
ES-SM Section Monitoring Errored Seconds (ES-SM) indicates the errored
seconds recorded in the OTN section during the PM time interval.
FC-PM Path Monitoring Failure Counts (FC-PM) indicates the failure counts
recorded in the OTN path during the PM time interval.
FC-SM Section Monitoring Failure Counts (FC-SM) indicates the failure counts
recorded in the OTN section during the PM time interval.
HP-BBE High-Order Path Background Block Error (HP-BBE) is an errored block
not occurring as part of an SES.
HP-BBER High-Order Path Background Block Error Ratio (HP-BBER) is the ratio of
BBE to total blocks in available time during a fixed measurement interval.
The count of total blocks excludes all blocks during SESs.
