Non-Intrusive voice Quality Analyzer
NIQA
The most known methods for quality evaluation of voice transmission systems were developed by Telecommunication Standardization Sector of International Telecommunications Union (ITU-T) in the middle of 90-s. Results of this work are presented in Recommendation P.800 (P.830) «Methods for subjective determination of transmission quality» [1, 2]. This document describes conditions for voice quality testing, audio contents, scoring and methods to evaluate results. Typically “Methods for subjective determination of transmission quality” are used to obtain mean subjective quality score according to five-digit scale (Mean Opinion Score – MOS).

Quality Assurance Testing
During difficult economic times, one of the first things that seems to get cut back is the quality assurance testing. Although quality assurance is often listed in the unimportant category, it can make a huge impact in your product and your company’s overall revenue and success. The fewer bugs your product ships with, the more your savings. In fact, the cost of fixing anomalies during the design and implementation phase of your development will be less than a quarter of what it will cost once your product has been released. It’s not the job of your customers to identify and test your products for you – unless you’d really like to alienate them and lose their future business. All it takes is one other vendor with a more stable, better designed product to cause your market share to drop like a rock (see WordPerfect vs. Word).

Quality Of Service
Traffic is prioritized according to its importance and some types of traffic are more sensitive to latency, jitter and packet loss than other. Xena offers QoS validation solutions in accordance with RFC 2544 and Y.1564, as well as advanced statistics functions that help users track, analyze and troubleshoot QoS to maintain a high service quality guarantee. Testing that link performance complies with a Service Level Agreement (SLA) includes verifying Frame Transfer Delay (FTD), Frame Delay Variation (FDV) and Frame Loss Ratio (FLR) at the Committed Information Rate (CIR) defined in the SLA. Verifying the SLA with the Xena1564 allows doing the test on a line simultaneously loaded with traffic from other services.
