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 columns 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.
LOSS Sets the Loss of Signal Seconds (LOSS) threshold. A LOSS is 1-second
period in which the E1 received signal is interrupted. The default value is
5 seconds.
UAS Sets the Unavailable Seconds (UAS) threshold. A UAS is a 1-second period
in which consecutive severely errored seconds cause an unavailable state. The
default is 0 seconds (Disabled).
CSS Sets the Controlled Slip Seconds (CSS) threshold. The default is 0 seconds
(Disabled).
BPVS Sets the Bipolar Violation Errored Seconds (BPVS) threshold. A BPVS is a 1-
second period in which at least one bipolar violation occurred. The default is
0 seconds (Disabled).
OOFS Sets the Out of Frame Seconds (OOFS) threshold. An OOFS is a 1-second
period in which a frame sync loss occurred. The default value is 5 seconds.
AISS Sets the Alarm Indication Signal Seconds (AISS) threshold. An AIS is a 1-
second period when unframed all ones are received. The default is 0 seconds
(Disabled).
RAS Sets the Remote Alarm Seconds (RAS) threshold. An RAS is generated by
the terminal equipment when an improper signal is received from the facility
(or upon receipt of unframed all ones). The default is 0 seconds (Disabled).
