View Presentation

The WebViewer™ uses a simple web browser with facilities to query the results either manually or automatically as well as output the results/statistics. These results include VQuad™ Call Event, User Defined Events, Bluetooth® events, Data Test (NetTest from PC and NetTest from Mobile Device), VQT, VBA, Delay and Echo Measurement results and Fax TxRx Events which can be saved to either text or Excel format. WebViewer™ includes support for user-defined statistics with both tabular and graphical outputs.

The WebViewer™ browser can also provide real-time status of the entire VQuad™/VQT network as well as remote accessibility of any node associated with the network. Transfer configuration files between the VQuad™ nodes and your local system for enhancements. Automatically send the updated configuration back to the VQuad™ system (or all VQuad™ systems). Rerun the test using the enhanced VQuad™ configuration, all from the WebViewer™ browser running on either Windows® based or Mac based systems (including iPhone and iPad devices).

GL’s VQuad™ provides automatic call control over several networks and supports transmit/capture of voice files in real-time from the various nodes. The degraded (recorded) voice files are automatically transferred to the Central Location where GL's VQT analyzes and generates the results using POLQA (ITU-T P.863), PESQ (ITU-T P.862), PAMS (ITU-T P.800), PSQM (ITU-T P.861) test methods. Additional analytical metrics are also provided as a result of the VQT algorithm including jitter, clipping, and level measurements.

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.

Components of GL's WebViewer™ Solution

Components of WebViewer™ solution

GL's WebViewer™ solution is a four tier architecture. The first layer consists of GL's VQuad™ which establishes the proper calls or direct connections between the near and far end using a variety of physical interfaces. The File Monitor transfers the degraded (recorded) voice files from the individual VQuad™ nodes to one of several VQT/VBA/EMU systems which are located on the second layer. Each VQT/VBA/EMU/Data Test applications automatically analyze the degraded voice file and transmit the analytical results to a single central database located at the Data Layer. This third layer provides a means for storing the captured results. The last layer is the Data Access Layer (Application Server) where the data presentation logic is contained. Each of these components is briefly explained below.


Data Layer

An Oracle or MS Access database (user specified) is used to store the analytical measurement results along with all pertinent data associated with the VQuad™/VQT/VBA/EMU/DataTest systems (Call progress events, error events, timestamps, Call ID, location information, Echo Measurements, Data Test Results, Fax Events, VQT PESQ and POLQA Events). This provides a very flexible and expandable architecture for data storage and data access. The database is accessed in real-time over the web using the WebViewer™.

The DataImport application is co-hosted with the database server running on the Data Layer. It collects the data posted by the probes and then updates the database using the collected data

Data Layer of the WebViewer™ solution


Application Server

The WebViewer™ provides an application server for accessing the VQuad™ Call progress events, user-defined error events, delay measurement results, Data Test results, Echo Measurement results, Fax Events and VQT PESQ/ VQT POLQA/VBA E-Model LQ/LQO/WB MOS measurements along with the additional analytical measurements including Call ID information. The results are queried over the internet using any browser-capable device such as desktops, table PCs MAC systems (Mac, iPhone, iPad) or PDAs. The application server is capable of serving the data in real-time or providing historic data based on customer selected filters.

Application layer of the WebViewer™ solution


Using the Application Server

Using any browser-capable-device, you can access all network results from anywhere in the world. When you open the WebViewer™, the following page will be displayed. The WebViewer™ browser can display the VQT PESQ results and ratings, VQT POLQA Events, VBA results including E-Model and ratings, VQuad™ Delay Measurement results (RTD, OWD, SNR, PDD), Echo Measurement results, Data Test results (TCP, UDP, VoIP, Route, HTTP, FTP, DNS, SMS, Email, PhoneInfo, SimInfo, and UEInfo), Fax Events and VQuad™ Call Control events including call failures and error events.
