Press Release : GL Announces Enhanced Voice Quality Testing Solutions

Gaithersburg, Maryland, USA – May 02, 2017 - GL Communications Inc., announced today its enhanced Voice Quality Testing solutions that include the important enhancements introduced to Voice Quality Testing software version 7.0, VQuad™ software version 9.0, and WebViewer™ version 5.2.

Speaking to the press, Mr. Robert Bichefsky, a Senior Manager for product development of the company said, “GL’s Voice, Video, and Data Quality Test Solution provides flexibility of connecting to and between any network, any service, and any interface. Enhanced VQuad™ application with Dual UTA HD supports very accurate One-Way and Round Trip Delay (RTD) measurements for 2-Wire and 4-Wire interfaces using the enhanced correlator algorithm. Both sides of the established call may be co-located on same Dual UTA HD or geographically separated. The measurements require GPS only for OWD and if the two sides of the call are geographically separated (not on same Dual UTA HD).”

He added, “Enhanced VQuad™ software also includes FXO Analysis feature which detects and display Line Current (mA) and Line Voltage (V) for the Dual UTA HD FXO devices. Also added to FXO analysis, Ring Voltage for all incoming calls and the ability to capture the Call Progress tones to PCM file for post-process analysis.

Now there is full support for VQuad™ CLI (both Windows® and Linux) and VQuad™ API (both Windows® and Linux).  VQuad™ CLI also supports both IPv6 and IPv4.

The VQuad™ Remote Access (Client) allows VQuad™ operations to be remotely controlled by one (or several) VQuad™ clients over a LAN, WAN, or Internet. Each VQuad™ client supports MS Windows, Unix, or Linux operating systems and includes a DLL component, which gives the users the ability to control the VQuad™ server remotely and to integrate within their own custom software.

The VQuad™ script editor has been enhanced to support several new commands associated with Audio and Call Control. Now it supports outward & Port-to-Port Loopback support with/without user-specified Delays (Dual UTA HD), Secondary PlaceCall with FXO Call Control, Support multiple individual Scripts within single test. This allows added flexibility when creating and executing VQuad™ scripts.”

Mr. Bichefsky further added, “The enhanced VQT software now includes full support for IPv6 as well as IPv4 (includes VQT, GL Listener, and VQTCLI) and VQT CLI and API enhanced to fully support both Windows® and Linux. Now POLQA supports 12 bit degraded file (NB, WB, SWB) and 8-bit a-Law and mu-Law voice files and it also supports Raw PCM as well as WAV files with auto-detect sampling for WAV files.

Now POLQA also supports user-specified Sampling Rate (specify any rate between 8K to 48K) and POLQA ITU version 2.4 for POLQA NB and SWB (including WB) modes. And it includes now reference voice files for NB/WB/SWB and 32K for Raw PCM and WAV. Also includes 8-bit a-Law and mu-Law Raw PCM files. The VQT is updated to Include POLQA delay measurement supports for Windows® Pro/Ultimate/Enterprise 7 and above, 32-bit/64-bit.”

He added, “GL's WebViewer™, a web-based interface accessing the central database for querying and filtering results, is further enhanced to simplify Custom Reports configuration and Google Map plotting.

Using WebViewer™, it is now possible to customize report generation with result statistics, tabular data, bar graphs, and line graphs.  Reports can be customized based on a combination of different parameters in Results View, Call Events, and Statistics.  WebViewer™ can generate and export the customized report in either text, excel or PDF formats, while also allow users to view results dynamically on WebViewer™.
