Table 8-7 DS1 Line PMs for the DS1 and DS1N Cards
Parameter Definition
DS1 CV-L
Code Violation Line (CV-L) indicates the number of coding violations
occurring on the line. This parameter is a count of bipolar violations
(BPVs) and excessive zeros (EXZs) occurring over the accumulation
period.
DS1 ES-L
Errored Seconds Line (ES-L) is a count of the seconds containing one or
more anomalies (BPV + EXZ) and/or defects (loss of signal) on the line.
DS1 SES-L
Severely Errored Seconds Line (SES-L) is a count of the seconds
containing more than a particular quantity of anomalies (BPV + EXZ >
1544) and/or defects on the line.
DS1 LOSS-L
Loss of Signal Seconds Line (LOSS-L) is a count of one-second intervals
containing one or more LOS defects.
Table 8-8 DS1 Receive Path PMs for the DS1 and DS1N Cards
Parameter Definition
DS1 Rx AISS-P
Receive Path Alarm Indication Signal (Rx AIS-P) means an alarm
indication signal occurred on the receive end of the path. This parameter
is a count of seconds containing one or more AIS defects.
DS1 Rx CV-P
Receive Path Code Violation (Rx CV-P) means a coding violation
occurred on the receive end of the path. For DS1-ESF paths, this
parameter is a count of detected CRC-6 errors. For the DS1-SF paths, the
Rx CV-P parameter is a count of detected frame bit errors (FE).
DS1 Rx ES-P
Receive Path Errored Seconds (Rx ES-P) is a count of the seconds
containing one or more anomalies and/or defects for paths on the receive
end of the signal. 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 Rx
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 Rx SAS-P
Receive Path Severely Errored Seconds Frame/Alarm Indication Signal
(Rx SAS-P) is a count of one-second intervals containing one or more
SEFs or one or more AIS defects on the receive end of the signal.
DS1 Rx SES-P
Receive Path Severely Errored Seconds (Rx SES-P) is a count of the
seconds containing more than a particular quantity of anomalies and/or
defects for paths on the receive end of the signal. 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 occurred. For DS1-SF paths, an SES is a
second containing either the occurrence of four FEs or one or more SEF
or AIS defects.
DS1 Rx UAS-P
Receive Path Unavailable Seconds (Rx UAS-P) is a count of one-second
intervals when the DS1 path is unavailable on the receive end of the
signal. 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.
