Error Status and Alarm Thresholds Table
The unit can be programmed to generate an alarm condition based on a
specific level of performance degradation. The Network Config screens
present a table that provides current error status and alarm threshold
information.
Acceptable alarm thresholds are set for periods of 15 minutes (900 seconds)
sampled every second. The error types listed in the following paragraphs can
be preset to a value between 0 and 900 seconds. Setting a field to “0” (zero)
disables the alarm on that statistic. To effectively disable alarm reporting, set
all fields to “0” (zero).
The 15-minute time frame is not based on the TR 54016 or T1.403 interval
boundaries, but is a time window based on the accumulated counts over the
previous fifteen 1-minute intervals. In all cases, if the number of actual
network errored seconds in the previous 15 minutes reaches the preset
threshold for the specified error type, an alarm condition is declared.
The four columnar sections of the status table are as follows:
• Status: Displays the current status of the network port.
• Alarm: Displays the alarm value of the network port. The unit declares an
alarm as soon as the count exceeds the threshold set.
• Count: Displays the number of events or occurrences of this statistic that
have been detected.
•
Threshold: Displays a read/write field that can be set to a desirable
threshold.
The table provides error status and alarm threshold information for the
following error parameters:
ES Sets the Errored Seconds (ES) threshold. An ES is a 1-second period in which
at least one logic error occurred. The default value is 45 seconds.
SES Sets the Severely Errored Seconds (SES) threshold. An SES is a 1-second
period in which at least 320 CRC errors or one Out -of-Frame (OOF) error
occurred. The default value is 5 seconds.
