Overview
While the growing requirements for voice quality testing within VoIP networks is growing, a major concern is testing the VoIP
phones 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 solution for testing the analog 2-wire
interfaces is the VQuad™ w/ FXO Analog option.
GL's VQuad™ w/ FXO Analog option and/or VoIP option, along with Voice Quality Testing (VQT), provides the complete automated
network testing solution including four analog 2-wire interfaces (RJ-11), up to eight SIP User Agents and the voice quality
measurement and analysis tools. Typical network applications include VoIP systems, PSTN, ATM networks, Frame Relay, and Wireless
Networks.
The GL VQuad™ w/ FXO Analog option supports four analog ports that 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 (four different tests
simultaneously) or the user may configure two pairs of synchronized analog ports (improved handling of call control and
sending/recording voice files). Each VoIP port associated with the VQuad may act independently (up to eight 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. In addition, the VQuad™ can send
and detect DTMF digits while the call is established. This allows two-stage dialing as well as path confirmation.
