Overview
GL's WebViewer™ provides the method to display and access, in real time, the entire VQuad™/VQT network including
all individual VQuad™ probes as well as the central location. Current status of the entire test is displayed along
with customized user statistics and results of the active tests.

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 Call Event, User Defined Events, Bluetooth™ ® events, Data Test (NetTest from PC and NetTest from
Mobile Device), VQT, VBA, Delay Measurement 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.
New VQuad™ Probe, self contained unit includes VQuad™, Dual UTA and PC. Control via Ethernet Remote Desktop (with support for mouse/keyboard).
See Buyer’s Guide for complete details. The degraded (recorded) voice files are automatically transferred to the Central Location where GL's VQT analyzes
and generates the PESQ MOS. Additional analytical metrics are also provided as a result of the VQT algorithm including jitter, clipping, and level
measurements.

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
analyzes the degraded voice file and transmits 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™/VQTVBA/EMU/DataTest systems (Call progress events, error events, timestamps, Call ID,
location information, Echo Measurements, Data Test Results, Fax 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/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, 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, and SMS), Fax Eventsand and
VQuad™ Call Control events including call failures and error events.
