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:
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).
Main Features:
- Single box solution with following available interfaces:
- Wireless / Landline / Handset interface using GL's UTA
- 2-Wire Analog (FXO) interface using GL's VQuad™
- VoIP interface
- TDM interface using GL's USB T1/E1 Analyzer
- Automated call control & traffic scripting
- Voice Band Analysis for all interfaces
- Voice Quality Testing (VQT) using PESQ (ITU-P.862.1)
- DTMF/MF and Frequency Tone Transmit / Detect
- Up to 8 simultaneous devices
- Drive Testing with GPS Mapping (most countries supported)
- Remote Accessible

VQT Solutions in TDM Networks
GL's voice quality testing solution for PSTN (testing analog 2-wire interfaces) includes GL's
VQuad™ with the optional T1E1 interface. The T1E1 interface is supported by GL’s
USB based T1E1 Analyzer unit or HD PCI T1E1 Analyzer cards. The VQuad™ provides
for automatic call establishment and teardown, sending and recording of voice files, and automatic analysis of
voice quality with VQT software.
