Voice, Video & Data Quality Testing
Across All Networks (VQuad™ - Dual UTA HD)

VQuad™ Software Ver 8.3 | VQT Software Ver 6.6 | WebViewer™ Software Ver 5.0  | Download Now!



Overview

The VQuad™ software is used to automatically send and record voice, video, and data traffic from four different types of network (Quad refers to 4 network types: Wireless, VoIP, TDM, & Analog). The VQuad™ uses a universal adapter such as Dual Universal Telephone Adapter High Density (Dual UTA HD), or VQuad™ Probe that provides multiple interfaces for connecting to any communication device on a network. The VQuad™ with any of the above hardware allows to test variety of networks, including Wireless (Bluetooth®, Wi-fi, 3G, 4G, LTE, PTT), VoIP, Analog, and TDM, practically allowing any end-point interfaces to be tested for voice, data, and video quality.

A single VQuad™ software supports up to 6 Dual UTA HD units, which means up to 12 telephony devices and/or 12 SIP User Agents in VoIP network can be controlled within a VQuad™. A minimum of two telephony interface types are supported per Dual UTA HD and all interfaces in the device may be configured together on a single PC. VQuad™ supports multiple tests to run simultaneously on devices connected to Dual UTA HD.

Dual UTA HD (High Density) includes support for Bluetooth® Wideband, FXO Wideband and SIP Wideband (ex: AMR WB), with which you can easily interface with any Mobile Device, FXO, or SIP devices supporting HD Voice.

Various associated applications (Voice QualityVideo QualityData testsEcho and Delay testsFax testsVoice Band Analysis) works with VQuad™ to provide "end-to-end assessment" with additional test and measuring capabilities. All the applications work in conjunction with the VQuad™ for automatically and remotely analysing the captured data and sending the test results to the central database. VQuad™ scripting allows for automated call control, and traffic simulation to conduct tests on Wireless, IP, PSTN and TDM networks.  Different types of traffic supported includes - NB and HD Voice, Video, Tones, DTMF/MF Digits, Fax, and other Data (HTTTP, UDP, TCP, SMS, Email, DNS, Route, FTP, ….).

With WebViewer™, the results can be queried and displayed on a remote client PC using web based browsers. Customized consolidated view of the VQuad™, call control and test results along with the graphical report can be generated. The status of each node in the network can be monitored. The Results, VQuad™ Nodes, and the Devices can be plotted in the WebViewer™ Google Maps using the GPS co-ordinates saved in the database. The output results can be exported to txt, xls, or pdf files.
