Interpretation of the Blocking value for the Optical Interface Attenuation Ratio parameter

This parameter is used to manage the added 40 or 80 wavelengths. You need to first create optical cross-connections for wavelengths on the WSM9 board. After optical cross-connections are created, the default value of this parameter is Blocking on the NMS for each wavelength. A wavelength whose Optical Interface Attenuation Ratio is Blocking cannot traverse the WSM9 board because the wavelength attenuation is the maximum. To enable the wavelength to traverse the WSM9 board, set the parameter to another value.
1. When the parameter value is Blocking, click the cell for editing. If you do not set it to another value, a dialog box will be displayed indicating the value range. When you close the dialog box, the attenuation is automatically set to the minimum value.
The value cannot be restored to Blocking.
2. If it is not set, click Query to return to the blocking state.
3. If you have configured the attenuation rate, it cannot be restored to the blocking state. You can delete the optical cross-connection to restore to the blocking state.
Blocking prevents impact of wavelength adding on the line and prevents transient service interruption over existing wavelengths. Set this parameter to Blocking, and allow wavelengths to traverse the board after the optical power is set to a proper value.
