Overview:

GL's VQuad™ (formerly AFT) makes assessing Voice Quality between and within differing networks easy, portable, and convenient. The system provides all necessary capability for automatic measurement of Voice Quality and QOS for any desired network including Wireless, VoIP, Analog, and TDM. The VQuad™ VQT System provides multiple interfaces for connecting to the Network using a single box solution. The single box solution enhances the user friendliness and the portability.

Available VQuad™ Interfaces:

• Automated testing of Wireless/WiFi/Mobile Radio phones
  
  
• Testing of VoIP/Digital phones
  
  
• Automated testing/simulation of PSTN (2-wire) phones
  
  
• Automated testing/simulation of VoIP soft phone (SIP and H.323 protocols supported)
  
  
• Automated testing of TDM networks (ISDN and CAS protocols supported)

Up to 8 devices (interfaces) can be controlled simultaneously on a single portable system. The system allows for independent traffic and independent automated Call Control via script configurations. This VQuad™ is fully automated, and when coupled with the GL VQT, the resultant MOS scores are automatically delivered to a remote client. A GPS option permits drive testing with VQT MOS scores plotted to local street maps (most all countries supported).
