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 columns of the status table are as follows:
•
Status
•
Alarm
•
Count
•
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).
Displays the current status of the network port.
Displays the alarm value of the network port. The unit
declares an alarm as soon as the count exceeds the threshold
set.
Displays the number of events or occurrences of this statistic
that have been detected.
A read/write field that can be set to a desirable threshold.
