The NET BER threshold is the maximum bit error rate allowed for
signals coming from the network. The EQP BER threshold is the
maximum bit error rate allowed for signals coming from the
network. Each can be set to any value between 10
-4
and 10
-9
. The
default is to 10
-6
.
Go to the EQP BER threshold field , and enter the positiv
value of the exponent. For example, for a bit error rate of 10
-5
,
enter 5 . Remember, the higher the exponent, the lower the
threshold. Do the same with the NET BER threshold field.
The default value is 6 , for 10
-6
.
To disable the alarm, select 0 (zero).
2. Set alarm thresholds and interval counts for each of these three
types of trouble seconds:
• Errored Seconds-Line - ES-L; that is, the number of seconds
with bipolar violations, indicating formatting errors. This refers
only to BPVs which are not an intentional part of B8ZS line
coding.
• Errored Seconds - ES; that is, the number of seconds with
CRC-6 errors, indicating a violation of data integrity
• Unavailable Seconds - UAS, that is, any second during which a
UASS (Unavailable Signal State) exists
First, an explanation of thresholds and interval counts.
