2007-5-17

GIX100, the excellent VoIP ATA product of EASY3CALL Technology, passed the strict benchmark test of a certain Asian telecom carrier. GIX100, is a next-generation SIP based VoIP telephone analogue adapter that is feature rich, easy to use and is competitively priced, has good performance not only in environment but also function test. The benchmark test is a professional and comprehensive test including environment, function and capability parts and it is the essential condition to enter the VoIP telecom carrier’s market. GIX100 performance is excellent especially in long run test and call completion rate test.

1. Call Completion Rate incorporated with Environmental Test

 

 Fig 1 Chamber Test Environment

The call completion rate test was done incorporated with environmental test in which the temperature and humidity changed sharply from -5ﾟC ~ 50ﾟC and 0~90%. The call completion rate of GIX100 is above 98% at the rate of 180 calls per hour for continuing 72 hours incorporated such protean environment. Below is the chamber test temperature and humidity change graph.

2. Long Run Test

In 8 hours continuing long run test, The voice quality of GIX100 is stable and as good as the beginning of getting through not matter using G.711A,G.711U or G.729 codec after a long run call lasted for 8 hours. And in the telecom carrier requirement the standard voice quality for G.729 and G.711 PAMS score should keep above 3.6 and 4.0. Below is the test environment graph and G.711A, G.711U and G.729 PAMS score of GIX100 for 8 hours long run which were tested by Agilent Voice Quality Tester (VQT).

Glossary:

PAMS: PAMS is an algorithm developed by British Telecom (BT) Labs, designed to provide an objective measure, which predicts the results of subjective listening tests (MOS) on telephony systems. PAMS uses a sensory model that, like any perceptual audio quality measurement algorithm, takes into account the physiology of the human ear, human cognitive processing models, and audio transmission characteristics. It evaluates the quality of audio signals in a similar way non-linear codecs encode and decode audio signals. That is, it also evaluates whether a particular piece of audio is distorted with regard to what a human listener would find annoying or distracting.

PAMS scores indicate listening quality and listening effort on a 1 to 5 scale that can be correlated to MOS scores.
