Definition
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.
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.
SEF/AIS Second (SASCP-PFE) is a count of one-second intervals
containing one or more far-end SEF/AIS defects.
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.
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 occur with no
CP-bit SESs. The ten seconds with no CP-bit SESs are excluded from
unavailable time.
