Table 8-4 DS1 Receive Path PMs for the XTC DS1 Cards
Parameter Definition
Note Under the Provisioning > Threshold tab, the DS1 cards have user-defined thresholds for the
DS1 receive (Rx) path PMs. In the Threshold tab they are displayed as Code Violation (CV),
Errored Seconds (ES), Severely Errored Seconds (SES), Unavailable Seconds (UAS), Alarm
Indication Signal (AISS), and Seconds Frame/Alarm Indication Signal (SAS) without the Rx
prefix.
DS1 Rx AISS-P Receive Path Alarm Indication Signal (Rx AISS-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 Alarm Indication Signal
(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 Severely Errored Frame (SEF) or Alarm
Indication Signal (AIS) defects. For DS1-SF paths, the Rx ES-P
parameter is a count of one-second intervals containing one or more
frame-bit errors (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 Alarm Indication Signal (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 Severely Errored Frame (SEF) or Alarm Indication Signal
(AIS) defects occurred. For DS1-SF paths, a Severely Errored Second
(SES) is a second containing either the occurrence of four frame-bit errors
(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 at the onset of 10 consecutive seconds
that qualify as Severely Errored Seconds (SESs), and continues to be
unavailable until the onset of 10 consecutive seconds that do not qualify
as Severely Errored Seconds Path (SES-Ps). The ten seconds with no
SES-Ps are excluded from unavailable time.
