Voice, Video, and Data Quality Test Solutions

The VQuad™ provides the one box solution for sending/recording voice/video/data over a variety of network interfaces in an automated and synchronized manner. The VQuad™ requires a universal adapter hardware such as  Dual UTA HD that provides multiple interfaces for connecting to any communication device on a network.  

Dual UTA HD (High Density) is a portable USB based hardware that supports 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. 

The VQuad™ works with any of the above hardware to perform end-to-end testing of variety of networks, including Wireless (Bluetooth®, Wi-fi, 3G, 4G LTE, 5G, PTT Mobile Radio), VoIP, Analog, and TDM, practically allowing any end-point interfaces to be tested for voice, data, and video quality. Various associated applications (Voice Quality, Video Quality, Data tests, Echo and Delay tests, Fax tests, Voice Band Analysis) works with VQuad™ to provide "end-to-end assessment" with additional test and measuring capabilities.

The VQuad™  supports automated call control for establishing calls and verifying the call is up prior to sending/recording voice. A GPS option permits time synchronization between two geographically separated systems as well as location information for Drive Testing. Thus the test results as well as the call control information can be plotted to local street maps (almost all countries supported). The VQuad™ ITS (Indoor Tracking System) provides the means to add location information to the VQuad™ results when GPS is not available (i.e. Underground Train systems).

With  Dual UTA HD, VQuad™ supports following connections:

• Wireless communication devices (Mobile phones, Smart phones (iPhone, Android), Military/Mobile radio, Bluetooth®, WiMax, WiFi, Broadband 3G, 4G LTE, 5G)
• WB 2-wire Analog Simulation (FXO port) using Dual UTA HD for connecting to ATA, PSTN, Gateways
• WB 4-Wire Analog interfaces supporting Tx/Rx Headset including HATS, Mobile Phone Headset, and any Handset Phone (RJ22 connection)
• Wireless radio (PTT supported) - Provides radio keying and sends/records audio
• Phone Handset for connecting to VoIP phones, Digital phones, Analog phones
• VoIP User Agent Simulation (supports both SIP and H.323 protocols)
• T1 E1 Simulation (supports both CAS and PRI ISDN protocols)
• GPS and ITS location tracking with results overlay
• Supports next-generation voice quality testing for fixed, mobile and IP networks using POLQA (ITU-T P.863)

Full support is also available for remote access of the VQuad™ and an SDK directly to the Dual UTA HD hardware (VQuad™ not required to be running).

A central databased stores the real-time and historic results from connected VQuad™ Probes.

Various associated applications (Voice Quality, Video Quality, Data tests, Echo and Delay tests, Fax tests, VBA) works with VQuad™ Probe 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. GL's WebViewer™ facilitates display of these test results, query and filter all results/events/errors from connected VQuad™ Probes using a simple web browser. All the nodes, and associated applications (Command Center, VQuad™, VQT, File Monitor, VBA, EMU, FAX, and VAC) can be accessed or controlled remotely through this web interface. The associated application status and the test results with GPS co-ordinates can be plotted on google maps. WebViewer™ also supports user-defined statistics and events configuration for both tabular and graphical outputs.

The VQuad™ provides the one box active QoS solution for sending/recording voice over a variety of network interfaces in an automated and synchronized manner. Using the GL VQT, analysis of the recorded voice files can automatically be executed from the VQuad™ in an intrusive manner. The VQT utilizes the ITU algorithms POLQA and PESQ LQ/LQO/WB. In addition to sending/recording voice, the VQuad™ also supports automated call control for establishing calls and verifying the call is up prior to sending/recording voice. VQuad™ now supports next-generation voice quality testing for fixed, mobile and IP-based networks using POLQA (ITU-T P.863) standard.

The GL Passive Quality of Service testing allows one to monitor voice anywhere within a network (using the desired VoIP/TDM/Analog Network probe) and gather statistics and quality of service measurements. The various network probes utilize GL hardware and software applications to support T1 E1, Analog, and VoIP networks. All network probes are non-intrusive and require no active testing on either side of the call. Rather, the non-intrusive Passive Monitoring utilizes the metrics from the voice or VoIP RTP and provides statistics, analytical measurements, and in certain cases MOS results.

The Global Network VQT system can be achieved using multiple VQuad™ systems (nodes) at various locations, accessing the network as wireless, analog, VoIP, and TDM. A central VQuad™ Command Center will provide full control of all nodes by running user-defined scripts for all desired tests. The VQT software will provide the voice analysis of all nodes along with additional analytical metrics, round trip delay measurements, jitter, clipping, and call control statistics. Finally, the WebViewer™ is used to remotely control the entire system, display real time statistics and status of the entire system, and query the VQT results and display in both tabular and graphical formats.

The WebViewer™ is a web application that can control the VQT, Command Center and individual VQuad™ applications and is capable of creating configurations/scripts, loading configurations/scripts, and starting/stopping the tests remotely. The WebViewer™ can also remotely query the VQT database and display the results both in tabular and graphical format. The WebViewer™ can access the VQT central database from a web interface for querying the results and displaying in both tabular and graphical formats.

The Network Voice Quality Testing Monitoring solution from GL Communications provides a complete intrusive testing solution for any desired network including Wireless, VoIP, Analog, and TDM. This GL solution consists of 5 parts: Distributed VQuad™ Probes, VQuad™ Command Center, array of analysis applications (VQT, VBA, VAC, MDC, & EMU), central location database, and Remote Client web-browsers. Many VQuad™ nodes (termination points) are supported, each VQuad™ Node supporting up to 8 interfaces, mobile or static. The Central Location includes the database (all analytical results and call progress events), Command Center for a more flexible control/scheduling of the Network tests, and the Analysis algorithms for Voice Quality and Echo Measurements. The WebViewer™ application provides user-defined querying of the central location database over the internet or local network.

This system provides real-time voice quality measurement across a diverse set of networks. Voice calls are automatically placed between end points; quality is measured and provided for display at an NMS. Voice measurements include MOS (Mean Opinion Score), round trip delay (RTD), jitter, clipping, voice levels, etc. The essential elements of this system are Wireless / Wireline / VoIP Nodes to establish calls and send / receive voice files in real-time, and the Regional Command Center (RCC) to control the nodes. It also includes Remote Client WebViewer™ to remotely control the RCC, access, sort, and display all data collected by the RCC.
