Configuring Optical Power Thresholds
Optical power thresholds provide a means of monitoring the signal power from the ITU laser. Four types
of thresholds are provided:
• Low alarm
• Low warning
• High warning
• High alarm
When a threshold is crossed, the system sends a message to the console.
Note The default values for the optical power receive thresholds are sufficient for most network
