Configuring threshold settings
Threshold settings are used for evaluating the NQA operation results, which can be classified into High,
Middle, Low, and Faulty levels. UCHM determines the quality of a test tunnel according to the NQA
operation result that reaches the thresholds set for a quality level.
To configure threshold settings:
1. Access the Parameter Settings page.
2. Click the Threshold Settings tab.
3. Configure the threshold parameters:
• Average Packet Loss (%)—Enter the rate of the average packet loss along the data path. The
value range is 0 to 100, accurate to one digit after the decimal point. The higher the value,
the worse the VoIP network quality.
• Maximum Delay (ms)—Enter the maximum delay, in milliseconds. The value range is 0 to 500.
The higher the value, the worse the VoIP network quality.
• Maximum Jitter (ms)—Enter the maximum jitter, in milliseconds. The value range is 0 to 200.
The higher the value, the worse the VoIP network quality.
• MOS Value—Enter the value of the Mean Opinion Scores for measuring the VoIP network
quality. The value rang is 1 to 5, accurate to one digit after the decimal point. The higher the
value, the better the VoIP network quality.
Configure these parameters for each of the High, Middle, and Low levels. If the test values do not
fall within any of the three levels, the result is Faulty.
An operation result falls within a quality level only when it has met all the parameters for this level.
