listed in the following paragraphs can be preset to a value selected from the
available enumeration list of thresholds (displayed as a pull-down menu).
Setting a threshold field to “None” disables the alarm for that condition. To
effectively disable alarm reporting, set all fields to “None.”
The 15-minute time frame is a time window based on the accumulated counts
over the previous 15 one-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 columns of the status table are as follows:
The table provides error status and alarm threshold information for the
following error parameters:
LOS Sets the Loss of Signal seconds threshold. A LOS is a 1-second period in
which the DDS received signal is interrupted. The default value is None.
OOF Sets the Out of Frame seconds threshold. An OOF is a 1-second period in
which a frame sync loss occurred. The default value is None.
OOS Sets the Out of Service seconds threshold. An OOS is a 1-second period
during which the Out of Service code is received. The default is None.
BPV Sets the Bipolar Violation Errored seconds threshold. A BPV is a 1-second
period in which at least one bipolar violation occurred. The default is None.
Reset Timer
The status table also provides a means for establishing the Reset Timer
threshold. This read/write field is used to establish the contiguous number of
seconds that an alarm parameter must be clear before the alarm is reset.
Applicable values range from 000 through 900. A value of “000” means the
alarm will never be reset. The default value is 30.
The Network screen also provides a “Clear Alarms” prompt, which resets the
alarm conditions and counts to zero.
Serial 1 and Serial 2 Screens
Because the Serial 1 and Serial 2 screens display the same parameters, only
the Serial 1 (Figure 4.8) screen is shown below. The Serial screens let you
view and make changes to the unit’s Serial interface configurations as
• 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 established
threshold.
•
Count Displays the number of events or occurrences of this
condition that have been detected.
• Threshold This forced-choice field can be set to a desired threshold for a
specific error condition. Available threshold choices are
None, 1, 2, 3, 4, 5, 10, 20, and 30.
