Table 8-5 DS1 Transmit Path PMs for the XTC DS1 Cards
Parameter Definition
Note Under the Performance tab, the displayed DS1 Tx path PM values are based on calculations
performed by the card and therefore have no user-defined thresholds. The tab is labeled
“Elect[rical] Path Threshold.”
DS1 Tx AIS-P Transmit Path Alarm Indication Signal (Tx AIS-P) means an alarm
indication signal occurred on the transmit end of the path. This parameter
is a count of seconds containing one or more Alarm Indication Signal
(AIS) defects.
DS1 Tx CV-P Transmit Path Code Violation (Tx CV-P) means a coding violation
occurred on the transmit end of the path. For DS1-ESF paths, this
parameter is a count of detected CRC-6 errors. For the DS1-SF paths, the
Tx CV-P parameter is a count of detected frame-bit errors (FEs).
DS1 Tx ES-P
Transmit Path Errored Seconds (Tx ES-P) is a count of the seconds
containing one or more anomalies and/or defects for paths on the transmit
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 Tx ES-P parameter
is a count of one-second intervals containing one or more frame bit error
(FE) events, or one or more CS events, or one or more SEF or AIS defects.
DS1 Tx SAS-P
Transmit Path Severely Errored Seconds Frame/Alarm Indication Signal
(Tx 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
transmit end of the signal.
DS1 Tx SES-P Transmit Path Severely Errored Seconds (Tx SES-P) is a count of the
seconds containing more than a particular quantity of anomalies and/or
defects for paths on the transmit 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 Tx UAS-P Transmit Path Unavailable Seconds (Tx UAS-P) is a count of one-second
intervals when the DS1 path is unavailable on the transmit 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 SESs. The ten seconds with no SESs are excluded from unavailable
time.
