DS3 SASCP-P
SEF/AIS Second (SASCP-PFE) is a count of one-second intervals
containing one or more near-end SEF/AIS defects.
DS3 SESCP-P
Severely Errored Seconds Path (SESCP-P) is a count of seconds
containing more than 44 CP-bit parity errors, one or more SEF defects, or
one or more AIS defects.
DS3 UASCP-P
Unavailable Seconds Path (DS3 UASCP-P) is a count of one-second
intervals when the DS3 path is unavailable. A DS3 path becomes
unavailable when ten consecutive SESCP-Ps occur. The ten SESCP-Ps
are included in unavailable time. Once unavailable, the DS3 path becomes
available when ten consecutive seconds with no SESCP-Ps occur. The ten
seconds with no SESCP-Ps are excluded from unavailable time.

Parameter Definition
DS1 AISS-P
Alarm Indication Signal Path (AIS-P) means an AIS occurred on the path.
This parameter is a count of seconds containing one or more AIS defects.
DS1 ES-P
Errored Seconds Path (ES-P) is a count of the seconds containing one or
more anomalies and/or defects for paths. For DS1-ESF paths, this
parameter is a count of one-second intervals containing one or more
CRC-6 errors, or one or more CS events, or one or more SEF or AIS
defects. For DS1-SF paths, the ES-P parameter is a count of one-second
intervals containing one or more FE events, or one or more CS events, or
one or more SEF or AIS defects.
DS1 SAS-P
Severely Errored Seconds Path Frame/Alarm Indication Signal (SAS-P)
is a count of one-second intervals containing one or more SEFs or one or
more AIS defects.
DS1 SES-P
Severely Errored Seconds Path (SES-P) is a count of the seconds
containing more than a particular quantity of anomalies and/or defects for
paths. For the DS1-ESF paths, this parameter is a count of seconds when
320 or more CRC-6 errors or one or more SEF or AIS defects occurs. For
DS1-SF paths, an SES is a second containing either the occurrence of
eight FEs, four FEs, or one or more SEF or AIS defects.
DS1 UAS-P
Unavailable Seconds Path (UAS-P) is a count of one-second intervals
when the DS1 path is unavailable. The DS1 path is unavailable when ten
consecutive SESs occur. The ten SESs are included in unavailable time.
Once unavailable, the DS1 path becomes available when ten consecutive
seconds occur with no SESs. The ten seconds with no SESs are excluded
from unavailable time.
