non-idle ordered sets.

 

 

 

 

 

 

 

 

 

 

 

OPR

 

Optical Power Received (OPR) is the measure of average optical power

 

 

 

 

 

 

received as a percentage of the nominal OPT.

 

 

 

 

 

 

 

 

 

 

 

OPR-AVG

 

Average Receive Optical Power (dBm).

 

 

 

 

 

 

 

 

 

 

 

OPR-MAX

 

Maximum Receive Optical Power (dBm).

 

 

 

 

 

 

 

 

 

 

 

OPR-MIN

 

Minimum Receive Optical Power (dBm).

 

 

 

 

 

 

 

 

 

 

 

OPT

 

Optical Power Transmitted (OPT) is the measure of average optical power

 

 

 

 

 

 

transmitted as a percentage of the nominal OPT.

 

 

 

 

 

 

 

 

 

 

 

OPT-AVG

 

Average Transmit Optical Power (dBm).

 

 

 

 

 

 

 

 

 

 

 

OPT-MAX

 

Maximum Transmit Optical Power (dBm).

 

 

 

 

 

 

 

 

 

 

 

OPT-MIN

 

Minimum Transmit Optical Power (dBm).

 

 

 

 

 

 

 

 

 

 

 

RS-BBE

 

Regenerator Section Background Block Error (RS-BBE) is an errored

 

 

 

 

 

 

block not occurring as part of an SES.

 

 

 

 

 

 

 

 

 

 

 

RS-BBER

 

Regenerator Section Background Block Error Ratio (RS-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.

 

 

 

 

 

 

 

 

 

 

 

RS-EB

 

Regenerator Section Errored Block (RS-EB) indicates that one or more bits

 

 

 

 

 

 

are in error within a block.

 

 

 

 

 

 

 

 

 

 

 

RS-ES

 

Regenerator Section Errored Second (RS-ES) is a one-second period with

 

 

 

 

 

 

one or more errored blocks or at least one defect.

 

 

 

 

 

 

 

 

 

 

 

RS-ESR

 

Regenerator Section Errored Second Ratio (RS-ESR) is the ratio of errored

 

 

 

 

 

 

seconds to total seconds in available time during a fixed measurement

 

 

 

 

 

 

interval.

 

 

 

 

 

 

 

 

 

 

 

RS-SES

 

Regenerator Section Severely Errored Second (RS-SES) is a one-second

 

 

 

 

 

 

period which contains 30 percent or more errored blocks or at least one

 

 

 

 

 

 

defect. SES is a subset of ES.

 

 

 

 

 

 

 

 

 

 

 

RS-SESR

 

Regenerator Section Severely Errored Second Ratio (RS-SESR) is the ratio

 

 

 

 

 

 

of SES to total seconds in available time during a fixed measurement

 

 

 

 

 

 

interval.

 

 

 

 

 

 

 

 

 

 

 

RS-UAS

 

Regenerator Section Unavailable Second (RS-UAS) is a count of the

 

 

 

 

 

 

seconds when the regenerator section was unavailable. A section becomes

 

 

 

 

 

 

unavailable when ten consecutive seconds occur that qualify as RS-UASs,

 

 

 

 

 

 

and it continues to be unavailable until ten consecutive seconds occur that

 

 

 

 

 

 

do not qualify as RS-UASs.

 

 

 

 

 

 

 

 

 

 

 

Rx AISS-P

 

Receive Path Alarm Indication Signal Seconds (AISS-P) means that an

 

 

 

 

 

 

alarm indication signal occurred on the receive end of the path. This

 

 

 

 

 

 

parameter is a count of seconds containing one or more AIS defects.

 

 

 

 

 

 

 

 

 

 

 

Rx BBE-P

 

Receive Path Background Block Error (BBE-P) is an errored block not

 

 

 

 

 

 

occurring as part of an SES.

 

 

 

 

 

 

 

 

 

 

 

Rx EB-P

 

Receive Path Errored Block (EB-P) indicates that one or more bits are in

 

 

 

 

 

 

error within a block.
