Which IP voice parameters can be monitored using the IP voice analysis function of a signal level meter (SLM)?

The IP voice analysis function of a signal level meter (SLM) is specifically designed to monitor parameters that are critical to the quality of voice over IP (VoIP) communications. Key parameters such as latency, jitter, and mean opinion score (MOS) are vital for assessing and ensuring the quality of voice calls.

Latency refers to the delay before a transfer of data begins following an instruction for its transfer, and it can critically affect the responsiveness of voice communication. Jitter is the variation in packet arrival times and can lead to uneven audio quality or gaps in conversation. The mean opinion score is a subjective measure of the quality of the audio perceived by listeners, often scaled from 1 to 5, which is essential for understanding the user experience.

In contrast, the other options focus on different aspects of network performance. While bandwidth and throughput provide insights regarding general network capacity, they do not directly measure voice quality. Signal strength and quality relate more to the physical aspects of the network rather than specific VoIP parameters. Packet loss and error rate are important for network performance but do not directly measure the subjective quality of voice calls in the way that the chosen parameters do. Thus, option B accurately reflects the parameters that the IP voice analysis function is designed to
