GL VQuad Voice File Transfer Application On Request On Request

The VQuad provides easy, portable, and convenient voice quality testing. The VQuad enables automatic measurement of Voice Quality and QOS for any desired network including Wireless (Bluetooth, Wi-Fi, 3G, 4G, LTE), VoIP, Analogue, and TDM.

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.

The VQuad tester uses a Dual Universal Telephone Adapter (Dual UTA) to provide multiple interfaces for connecting to the Network, in a single box solution. The 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.

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).

The system allows independent traffic and independent automated Call Control via script configurations. The VQuad is fully automated, and when coupled with the VQT software, the resultant MOS scores are automatically delivered to a remote client.

A GPS sync port on the Dual UTA permits precise time synchronization between two geographically separated systems as well as location information for drive testing. It allows sending and receiving audio files, 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. VQT MOS scores as well as the Call Control information can be plotted to local street maps (most countries supported).

The 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 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.

The VQuad Lite application with Dual Universal Telephony Adapter (UTA) supports a maximum of 2 Devices in FXO, or Mobile Wireless network, with each device associated to one telephony device (Bluetooth / FXO). The Dual Universal Telephony Adapter (Dual UTA) kit with VQuad Lite application provides connectivity to the following telephony equipment:

  • Mobile Phones with Bluetooth - Works with all Bluetooth phones for both call control and send/record audio functions. Bluetooth also performs RSSI, Battery level functions, Network verification.
  • RJ-11 POTS lines - Detect dial tone, go off hook, CallerID detection, send digits (two stage dialling), answer calls, detect a variety of Special Information Tones (SIT), send/record audio for Voice Quality measurement, and more.
