Parameter Definition
DS3 CVCP-P
Code Violation (CVCP-PFE) is a parameter that is counted when the three
FEBE bits in a M-frame are not all collectively set to 1.
DS3 ESCP-P
Errored Second (ESCP-PFE) is a count of one-second intervals containing
one or more M-frames with the three FEBE bits not all collectively set to
1 or one or more far-end SEF/AIS defects.
DS3 SASCP-P
SEF/AIS Second (SASCP-PFE) is a count of one-second intervals
containing one or more far-end SEF/AIS defects.
DS3 SESCP-P
Severely Errored Second (SESCP-PFE) is a count of one-second intervals
containing one or more 44 M-frames with the three FEBE bits not all
collectively set to 1 or one or more far-end SEF/AIS defects.
DS3 UASCP-P
Unavailable Second (UASCP-PFE) is a count of one-second intervals
when the DS3 path becomes unavailable. A DS3 path becomes
unavailable when ten consecutive far-end CP-bit SESs occur. The ten
CP-bit SESs are included in unavailable time. Once unavailable, the DS3
path becomes available when ten consecutive seconds with no CP-bit
SESs occur. The ten seconds with no CP-bit SESs are excluded from
unavailable time.

Parameter Definition
CV-V
Code Violation VT Layer (CV-V) is a count of the BIP errors detected at
the VT path layer. Up to two BIP errors can be detected per VT
superframe; each error increments the current CV-V second register.
ES-V
Errored Seconds VT Layer (ES-V) is a count of the seconds when at least
one VT Path BIP error was detected. An AIS-V defect (or a lower-layer,
traffic-related, near-end defect) or an LOP-V defect can also cause an
ES-V.
SES-V
Severely Errored Seconds VT Layer (SES-V) is a count of seconds when
K (600) or more VT Path BIP errors were detected. An AIS-V defect (or
a lower-layer, traffic-related, near-end defect) or an LOP-V defect can
also cause an SES-V.
UAS-V
Unavailable Second VT Layer (UAS-V) is a count of the seconds when
the VT path was unavailable. A VT path becomes unavailable when ten
consecutive seconds occur that qualify as SES-Vs and continues to be
unavailable until ten consecutive seconds occur that do not qualify as
SES-Vs.
