Chapter 11 Performance Monitoring

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 11-25and 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.

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.
