Parameter Definition
AISS-P AIS Seconds Path (AISS-P) is a count of one-second intervals containing
one or more alarm indication signal (AIS) defects.
BBE-PM Path Monitoring Background Block Errors (BBE-PM) indicates the
number of background block errors recorded in the optical transport
network (OTN) path during the PM time interval.
BBE-SM Section Monitoring Background Block Errors (BBE-SM) indicates the
number of background block errors recorded in the OTN section during
the PM time interval.
BBER-PM Path Monitoring Background Block Errors Ratio (BBER-PM) indicates
the background block errors ratio recorded in the OTN path during the PM
time interval.
BBER-SM Section Monitoring Background Block Errors Ratio (BBER-SM)
indicates the background block errors ratio recorded in the OTN section
during the PM time interval.
BIT-EC Bit Errors Corrected (BIT-EC) indicated the number of bit errors
corrected in the DWDM trunk line during the PM time interval.
CSS Controlled Slip Seconds (CSS) indicates the count of the seconds when at
least one or more controlled slips have occurred.
CSS-P Controlled Slip Seconds Path (CSS-P) indicates the count of the seconds
when at least one or more controlled slips have occurred.
CVCP-P Code Violation CP-bit Path (CVCP-P) is a count of CP-bit parity errors
occurring in the accumulation period.
CVCP-PFE Code Violation CP-bit Path (CVCP-PFE) is a parameter that is counted
when the three far-end block error (FEBE) bits in an M-frame are not all
collectively set to 1.
CGV Code Group Violations (CGV) is a count of received code groups that do
not contain a start or end delimiter.
CV-L Line Code Violation (CV-L) indicates the number of coding violations
occurring on the line. This parameter is a count of bipolar violations
(BPVs) and excessive zeros (EXZs) occurring over the accumulation
period.
CV-P Near-End STS Path Coding Violations (CV-P) is a count of BIP errors
detected at the STS path layer (that is, using the B3 byte). Up to eight BIP
errors can be detected per frame; each error increments the current CV-P
second register.
CV-PFE Far-End STS Path Coding Violations (CV-PFE) is a count of BIP errors
detected at the STS path layer (that is, using the B3 byte). Up to eight BIP
errors can be detected per frame; each error increments the current
CV-PFE second register.
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.
