Looking for a Portable platform for VQT Analysis! Click here to know more
Overview
The VQuad™ (Voice Quad) software is used to automatically send and record voice files from four different types of network
(Quad meaning 4 networks: Wireless, VoIP, TDM, & Analog). VQuad™ supports up to 8 telephony devices simultaneously. A minimum of two
telephony nodes are required for transferring files and these nodes may be configured together on a single PC, or with each node served by one PC.
GL's VQuad™ along with the Voice Quality Testing (VQT), Echo Measurement Utility (EMU), Voice Band Analyzer
(VBA) & Data Test applications allows end-to-end intrusive testing for voice, data and video quality, echo, noise, call failure rates, and
other impairments between and within different networks. The system is designed for easier, portable, and convenient testing. The system provides all
necessary capability for automatic measurement of Voice Quality and QOS for any desired network including Wireless (Bluetooth®, Wi-fi, 3G, 4G, LTE),
VoIP, Analog, and TDM.

The VQuad™ - uses a Dual Universal Telephone Adapter (Dual UTA) provides multiple interfaces for connecting to the Network using a single
box solution. Dual UTA is a low power USB device that has been fully tested with an ultra-portable Dual Core NetBook (no external power required),
which allows both the VQuad™ and VQT to reside and operate simultaneously on the same NetBook.
A GPS sync port on the Dual UTA permits precise synchronization of sending and receiving audio functions, one-way delay (OWD), and round trip delay (RTD).
The Dual UTA can be directed to automatically send and record sample voice files between nodes of a telephony network.
Available VQuad™ Interfaces:
Full support is also available for remote access of the VQuad™ and an SDK directly to the Dual UTA hardware
(VQuad™ not required to be running).
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
VQT software, the resultant MOS scores are automatically delivered to a remote client. A GPS option permits time synchronization between two geographically
separated systems as well as location information for drive testing. Thus, VQT MOS scores as well as the Call Control information can be plotted to local
street maps (most all countries supported). Finally, Round Trip Delay and One Way Delay measurements are provided directly via the
Dual UTA hardware.
VQuad™ supports Data Testing including TCP, UDP, VoIP, Route, HTTP, FTP, DNS and SMS. The Data Tests are configured via the VQuad™
scripting and support the PC Ethernet connection (wired, WiFi, Broadband 3G/4G) or mobile device. Using the optional GL's Mobile Device Controller application
and the supporting downloadable apps on the Smartphones (iPhone, Android), the VQuad™ can remotely perform the data tests when the phone is
within a voice call or outside a voice call
VQuad™ with Dual UTA (VQT270) supports Fax testing (sending and receiving) up to 4 independent
and simultaneous T.30 faxes. The user can configure the Tx and Rx fax rate from 2400 baud to 33600 baud with V.34 fully supported. Interfaces supported for
fax generation include 2-wire FXO and 4-wire analog. Support for additional interfaces such as T1/E1 and VoIP (T.38) are coming soon.
GL's new VQuad™ Probe is an all-in-one self-contained VQuad™ with Dual UTA test instrument. This comprehensive hardware device incorporates
all the features of the current VQuad™ with Dual UTA unit such as portability and remote accessibility along with the necessary PC hardware with Win7 OS.
The VQuad™ probe can be controlled via Ethernet Remote Desktop (with support for mouse/keyboard) and is of same length as the current Dual UTA
hardware, but about twice as high and 50% wider.
