Parameter Definition Description
Section
CV-S Code Violation - Sec-
tion
This parameter indicates the number of coding violations
encountered at the Section Layer.
SEFS-S Severely Errored
Framing Seconds-
Section
This parameter indicates the number of seconds that
contain one or more SEF events - only counted at the
Section Layer.
ES-S Errored Seconds -
Section
This parameter indicates the number of seconds with
one or more coding violations or one or more incoming
defects (SEF, LOS) at the Section Layer.
SES-S Severely Errored Sec-
onds - Section
This parameter indicates the number of seconds with x
or more coding violations at the Section Layer, or a sec
-
ond during which at least one or more incoming defects
at the Section Layer has occurred (Values of x vary
dependent upon the line rate and the Bit Error Rate).
Line
CV-L Code Violation - Line This parameter indicates the number of coding violations
encountered at the Line Layer.
ES-L Errored Second -
Line
This parameter indicates the number of seconds with
one or more coding violations or an incoming defect (AIS-
L) at the Line Layer.
SES-L Severely Errored Sec-
onds - Line
This parameter indicates the number of seconds with x
or more coding violations at the Line Layer, or a second
during which at least one or more incoming defects at
the Line Layer has occurred (Values of x vary dependent
upon the line rate and the Bit Error Rate).
UAS-L Unavailable Seconds
- Line
This parameter indicates the time in seconds that the
Line Layer has been unavailable for data delivery.
Path
CV-P Coding Violations -
Path
This parameter indicates the number of coding violations
encountered at the Path Layer.
ES-P Errored Seconds -
Path
This parameter indicates the number of seconds with
one or more coding violations or one or more incoming
defects (SAIS-P, LOP, UNEQ-P) at the Path Layer.
