Table C-3. Sync Data Port Configuration Options (5 of 5)
Excessive Error Rate Threshold: 10E-4
10E-4 10E-5 10E-6 10E-7 10E-8 10E-9
Sets the error rate threshold that determines when an Excessive Error Rate (EER)
condition is declared for a particular port. The error rate selected by this configuration
option is determined by the ratio of the number of CRC5 errors to the total number of
bits received over a set period of time.
10E-4 – 10E-4 Threshold. For example, at 1536 kbps, EER is declared if more than
1,535 CRC5 errors are detected in a 10-second period. It is cleared with less than
1,536 errors in ten seconds.
10E-5 – 10E-5 Threshold. For example, at 1536 kbps, EER is declared if more than
921 CRC5 errors are detected in a 60-second period. It is cleared with less than
922 errors in sixty seconds.
10E-6 – 10E-6 Threshold. For example, at 1536 kbps, EER is declared if more than
92 CRC5 errors are detected in a 60-second period.
It is cleared with less than 93 errors
in sixty seconds.
10E-7 – 10E-7 Threshold. For example, at 1536 kbps, EER is declared if more than
9 CRC5 errors are detected in a 60-second period. It is cleared with less than 10 errors
in sixty seconds.
10E-8 – 10E-8 Threshold. For example, at 1536 kbps, EER is declared if more than
41 CRC5 errors are detected in three 15-minute intervals. It is cleared with less than
42 errors in three 15-minute intervals.
10E-9 – 10E-9 Threshold. For example, at 1536 kbps, EER is declared if more than
4 CRC5 errors are detected in three 15-minute intervals. It is cleared with less than
5 errors in three 15-minute intervals.
