CLI Command List
Errored Seconds (ES) For ESF links, the number of one-second intervals
containing one or more Path Code Violations OR one or more
Severely Errored Frame defects OR one or more Controlled Slip
events OR a detected AIS defect.
For D4 links, the presence of Bipolar Violations also triggers an
Errored Second.
ES is not incremented during an Unavailable Second.
Severely Errored
Seconds
(SES) For ESF links, the number of one-second intervals
containing 320 or more Path Code Violation Error Events OR
one or more Out of Frame defects OR a detected AIS defect.
For D4 signals, The number of one-second intervals with
Framing Error events, or an OOF defect, or 1544 LCVs or more.
Controlled slips are not included in this parameter.
SES is not incremented during an Unavailable Second.
Severely Errored
Frame Seconds
(SEFS) The number of one-second intervals containing one
or more Out of Frame defects OR a detected AIS defect.
Line Errored Seconds (LES) The number of one-second intervals containing one or
more line errors.
Controlled Slip Seconds (CSS) The number of one-second intervals containing one or
more controlled slips.
Bursty Errored Seconds (BES) Also known as Errored Second type B. The number of
one-second intervals with fewer than 320 and more than 1 Path
Coding Violation error event, no Severely Errored Frame
defects, and no detected incoming AIS defects. Controlled slips
are not included in this parameter.
BES is not incremented during an Unavailable Second.
Degraded Minutes (DM) The total number of minutes in which the estimated error
rate exceeds 1E-6 but does not exceed 1E-3. Degraded Minutes
are determined by collecting all of the Available Seconds,
removing any Severely Errored Seconds, grouping the result in
60-second long groups, and counting a 60-second long group
(one minute) as degraded if the cumulative errors during the
seconds present in the group exceed 1E-6. Available seconds are
merely those seconds that are not Unavailable (UAS).
Line Code Violations (LCV or CV) The total number of line code violations that have
been detected during the measurement interval. An LCV is the
occurrence of a Bi-polar Violation (BPV) or Excessive Zeros.
