Performance Monitoring Parameter Definitions
For pointer justification count definitions, depending on the cards in use, see the “11.7.1 STM1 Port
Performance Monitoring Parameters” section on page 11-25 and the “11.7.2 STM4 Port Performance
Monitoring Parameters” section on page 11-27.
In CTC, the count fields for PPJC and NPJC PM parameters appear white and blank unless they are
enabled on the Provisioning > Optical > Line tab PJVC4MON# drop-down list.
11.4 Performance Monitoring Parameter Definitions
Table 11-2 gives a definition for each type of PM parameter found in the ONS 15310-MA SDH.

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 Path Background Block Error (BBE) is an errored block not occurring as
part of a severely errored second (SES).
BBE-PM Path Monitoring Background Block Errors (BBE-PM) indicates the
number of background block errors recorded in the optical transfer
network (OTN) path during the PM time interval.
BBER Path Background Block Error Ratio (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.
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.
BBE-SM Section Monitoring Background Block Errors (BBE-SM) indicates the
number of background block errors recorded in the optical transport
network (OTN) section during the PM time interval.
BIE The number of bit errors (BIE) corrected in the dense wavelength division
multiplexing (DWDM) trunk line during the PM time interval.
BIEC The number of Bit Errors Corrected (BIEC) in the DWDM trunk line
during the PM time interval.
CGV Code Group Violations (CGV) is a count of received code groups that do
not contain a start or end delimiter.
CVCP-P Code Violation Path (CVCP-P) is a count of CP-bit parity errors occurring
in the accumulation period.
CVCP-PFE Code Violation (CVCP-PFE) is a parameter that is counted when the three
far-end block error (FEBE) bits in a M-frame are not all collectively set
to 1.
MS-EB Indicates the number of coding violations occurring on the line. This
parameter is a count of BPVs and EXZs occurring over the accumulation
period.
