  • Hello Neeeewbie.

    You can use DDM to check your power thresholds.

    Transmit and Receive Power Thresholds
    Transmit Low Alarm Threshold 0.1000mW -10.00dBm
    Transmit High Alarm Threshold 3.1623mW 5.00dBm
    Transmit Low Warning Threshold 0.1585mW -8.00dBm
    Transmit High Warning Threshold 1.9953mW 3.00dBm
    Receive Low Alarm Threshold 0.0398mW -14.00dBm
    Receive High Alarm Threshold 2.1878mW 3.40dBm
    Receive Low Warning Threshold 0.0794mW -11.00dBm
    Receive High Warning Threshold 1.7378mW 2.40dBm

  • Hello Neeeewbie.

     

    Knowing how to extract that value, you can configure a custom MIB to report that state.

    Also, you can configure a periodic iCall to monitor that value and log a message when the issue occurs.
