Press Release: GL Announces VQuad™ with
Enhanced Voice & Data Testing Solutions

Gaithersburg, Maryland, USA - July 18, 2011 - GL Communications Inc., announced today the release of VQuad™ with enhanced Voice and Data Testing Capabilities Ė VQuad™ and VQuad™ - Lite (ver 6.4), Mobile Device Controlle, and WebViewer™. Speaking to the press, Mr. Robert Bichefsky Senior Manager at GL said, "Communications is dramatically changing right now, as ďmobilityĒ and ďIPĒ technologies such as LTE, Advanced LTE, WiMax, 3G, and Broadband Internet, lead this transformation. As these technologies are rolled out, basic voice/data quality will ultimately determine the fate of carriers and end equipment manufacturers. Simple and effective methods of testing voice and data are sorely needed - GLís mobile test solution provides this capability with the flexibility of connecting to and between any device (including Apple and Android), any network, any service, and any interface.

Typical networks that are supported by GL's VQuad™ - Dual UTA hardware/software include Wireless (WiFi, Bluetooth®, 3G, 4G, LTE), Broadband Internet (3G, 4G), VoIP SIP, PSTN, and TDM.Ē

He elaborated, ďGLís enhanced VQuad™ product can connect to any mobile, landline or VoIP device and provide automated Voice and Data Quality analysis on the associated network. The VQuad™ solution utilizes user-friendly software with a USB based hardware component (Dual UTA Ė Universal Telephony Adapter) for connecting to devices and testing various networks. Added to the GL VQuad™ solution is Data Testing for all wireless networks. Using the VQuad™ along with a standard PC internet connection, automated tests including TCP, UDP, HTTP, VoIP, Route, FTP and DNS are supported.

Also available is the GLís NetTest package for Data Testing on any supported Mobile Device and is remotely controlled via the GL Mobile Device Controlle system.

GL's WebViewer™ provides the method to control, monitor 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.Ē

Mr.Bichefsky further explained, ďGLís Mobile Device Controlle (MDC) provides a liaison to all supported Apple/Android based mobile devices for conducting data tests. The Data tests can be remotely started irrespective if the mobile device is in close proximity of the VQuad™.

GLís latest release the VQuad™ - Lite application with Dual Universal Telephony Adapter (UTA), is the Lite version of VQuad™ is geared towards field technicians based on the simplicity of the software and ease of operation. The VQuad™-Lite supports a maximum of two FXO and/or Mobile Bluetooth devices.Ē

Some of the important Features of VQuad™ are:

  • Single box portable solution interfacing with the following:
    • Any Communication Device (Mobile phone, Smart phones (iPhone, Android), Military/Mobile radio, Bluetooth®, WiMax, WiFi)
    • 2-Wire POTS (connect to PSTN, ATA, Media Gateway)
    • SIP Call Agent (act as a SoftPhone and configure Proxy and Registrar).
    • VoIP Ethernet (connect directly to any SoftPhone or any digital/VoIP hardware phone)
    • T1/E1 (CAS and PRI ISDN protocols supported)
  • Local VQuad™ can control remote VQuad™ systems to expand testing for an entire network. All results and events are automatically transferred to a Central Database (optional WebViewer™ required).
  • Automated Data Testing for Apple/Android Mobile Devices including TCP, UDP, VoIP, Route, HTTP, FTP, and DNS.
  • Automated Data Testing for PC Internet connection (Broadband 3G/4G, WiFi, Wired) including TCP, UDP, VoIP, Route, HTTP, FTP, and DNS.

Some of the important Features of WebViewer™ are:

  • Support for PC and Apple (MacBook, iPad, iPhone) web browser
  • All results from individual VQuad™ probes, VQT, VBA, and EMU are automatically sent to WebViewer™ central database.
  • Results include Voice Quality, Data Testing, Delay Measurements, Call Control, user generated events, and user-defined statistics
  • Customized Reports for both Results and Statistics can be output as either Excel or Text formats.
  • Database backup, export and import utilities
  • Query results based on a variety of mechanisms including, but not limited to, time, device ID, location/test name, result threshold, result condition and value
  • Display all result events or display events on per call basis (all results within call are averaged with min/max values provided)
