GL Conveys the Availability of its VQTWebViewer™ Software

GL Communications Inc. , conveyed today the availability of its VQT WebViewer™ software.Gaithersburg, MD June 30, 2012

Speaking to the press, Mr. Robert Bichefsky Senior Manager of the company said, “GL's WebViewer™ provides the method to display and access, in real time, the entire VQuad™/VQT network including all individual VQuad™ probes as then as the central location. Current status of the entire test is displayed along with customized user statistics and results of the active tests.”

It can as well provide real-time status of the entire VQuad™/VQT network as then 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. Rerun the test using the enhanced VQuad™ configuration, all from the WebViewer™ browser running on either Windows® based or Mac based systems.”

Mr.Bichefsky furthermore added, “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 voice files are automatically transferred to the Central Location where GL's VQT analyzes and generates the PESQ MOS. Additional analytical metrics are as well 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 just as portability and remote accessibility along with the necessary PC hardware with Win7 OS. The VQuad™ probe can be controlled via Ethernet Remote Desktop and is of same length as the current Dual UTA hardware, nevertheless about twice as high and 50% wider.”

·WebViewer™ access points support PC, Netbook, Macbook, and mobile devices just as iPhone, Android, and iPad. View results remotely anytime anywhere using any of these access points.

·Results include VQT, Call Control, Echo Measurements, Data Test, Delay Measurements, Fax Tx Rx Events.

Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP (Voice over Internet Protocol) networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.

GL’s VoIP and IP products generate / analyze thousands of calls and traffic simultaneously with traffic types just as frames, packets, voice files, digits, video, tones, noise, and fax. Nearly all codecs are supported including G.711, G.729, AMR, EVRC-A, B, C, GSM, iSAC, and many more. Additional features include visual analysis, real-time listening, and recording. The product line as well includes Ethernet / IP Testing capability that simulates and checks frame transport and throughput parameters of Ethernet and IP networks, including delay, errors and other impairments.

GL's Voice Quality Testing product line complements all of GL's products. Using ITU-standard algorithms, GL's VQT provides a widely accepted solution for assessing voice quality in the telecom industry. Voice Quality Testing across multiple networks is available.

GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and LTE (Long Term Evolution, latest standard in the mobile network technology) networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal measurements.

The broadest range of simulation

GL’s Echo Canceller testing solutions provide the broadest range of simulation and analysis, including line and acoustic echo. GL’s compliance testing per G.168. G.167 and P.340 across TDM, IP, VoIP and Wireless networks is widely accepted in the industry.

GL’s wireless VQT solutions help assessing impairments to voice quality just as poor mobile phone quality, voice compression and decompression algorithms, delay, loss and gain in speech levels, noise, acoustic and landline echo, and other distortions are easily assessed and accurately measured.

Wide variety of communications facilities

GL’s Handheld data testers can test a wide variety of communications facilities and equipment including T1, fractional T1, E1, fractional E1, T3 and E3 modems, multiplexers, CSU, DSUs, T1 CSUs, DTUs, NTUs and TIUs and more. The testers provide convenience, economy, and portability for nearly any interface, including RS232, RS-422, RS-530, X.21, T1, E1, T3, E3, and many others.

GL’s Network Surveillance and Monitoring products include Probes for TDM, IP, VoIP, ATM, and Wireless networks. An open standards based approach provides a scalable, feature rich, real-time access to network characteristics. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
