Set Frame Threshold Alarm
1E-5 = 1 x 10
-5
1E-4 = 1 x 10
-4
1E-3 = 1 x 10
-3
1E-2 = 1 x 10
-2
1E-1 = 1 x 10
-1
Once the Frame Error Ratio exceeds the preset threshold value, it will then switch the ACTIVE
PATH to the PROTECTION PATH.
Set Frame Threshold (Cleared)
1E-7 = 1 x 10
-7
5E-6 = 5 x 10
-6
1E-5 = 1 x 10
-5
1E-4 = 1 x 10
-4
1E-3 = 1 x 10
-3
Once the Frame Clear Ratio achieves the preset threshold value, it will then switch back from
PROTECTION PATH to the ACTIVE PATH.
Set CRC Threshold Alarm
Set Cyclic Redundancy Check error ratio
1E-5 = 1 x 10
-5
1E-4 = 1 x 10
-4
1E-3 = 1 x 10
-3
1E-2 = 1 x 10
-2
1E-1 = 1 x 10
-1
Once the Cyclic Redundancy Check Error Ratio exceeds the preset threshold value, it will then
switch the ACTIVE PATH to the PROTECTION PATH.
Set CRC Threshold (Cleared)
Set Cyclic Redundancy Check alarm clear ratio
1E-7 = 1 x 10
-7
5E-6 = 5 x 10
-6
1E-5 = 1 x 10
-5
1E-4 = 1 x 10
-4
1E-3 = 1 x 10
-3
Once the Cyclic Redundancy Check Clear Ratio achieves the preset threshold value, it will then
switch back from PROTECTION PATH to the ACTIVE PATH.
Measure Error Ratio
MEARSURE ERROR RATIO will measure and display Line Code Violation (LCV), Cyclic
Redundancy Check (CRC), and Frame Error (FRME).
