Voice Quality Testing on VoIP ATAs

Overview

With the growing requirements for voice quality testing within VoIP networks is a major concern in testing the VoIP network, VoIP phones, VoIP Softphones and the analog Telephone Adaptors (ATA) that will be used within the VoIP networks. The VoIP phones and ATA's must be free of noise and other hindrances that may cause a degraded voice quality when using this equipment.

Assuring uninterrupted high quality voice within a network is critical irrespective of what type of network is carrying the voice. Testing these networks can become cumbersome, time consuming and quite costly. GL's VQuad™ with Dual UTA HD provide the solution for testing WB Analog 2-wire interfaces which connects to any PSTN, ATA, next generation media gateway. Dual UTA HD analog interface supports both Wide Band (WB) and Narrow Band (NB) HD and SD Audio. The  Dual UTA HD includes dual Analog FXO interfaces (RJ11) which provides Off/On- Hook, DTMF Dialing, Flash Hook, Tone Detection (Dialtone, Ringback, Busy, Fast Busy, SIT) and CallerID. The Dual UTA HD Analog interface supports two-stage dialing, IVR testing, Voice Quality Testing, Delay Measurements, and Echo Measurements. The product can be configured to automatically send/record a multitude of voice files and to perform VQT algorithms immediately after the voice file recording is complete.

The GL VQuad™ w/ Dual UTA HD FXO Analog ports may be connected to the analog side of any ATA. The VoIP side of the ATA can be directly connected to the VQuad with VoIP option. Thus, the VQuad can support one or both sides of the ATA for call generation and traffic/voice analysis. Using the VQuad™ user-friendly GUI, the user can place calls to any desirable number as well as answer incoming calls in a manual or automated fashion. The VQuad™ can be configured manually to generate calls and send/record voice files or configured to automatically place calls and send/record a multitude of voice files to be used in the VQT algorithms. While in automode, the GL VQT may be configured to automatically perform the VQT algorithms immediately after the recorded voice file is complete. Each analog port associated with the VQuad may act independently (two different tests simultaneously). Each VoIP port associated with the VQuad may act independently (up to 12 different tests simultaneously). Each analog/VoIP port may be configured for Time Triggering, Digit Triggering, or Frequency Tone Triggering (thus easily synchronizing the analog/VoIP ports with the other GL VQuad™ interfaces such as Wireless.
