GL Conveys the Availability of its VQuad™ Software

Speaking to the press, Mr. Robert Bichefsky Senior Manager of the company said, "The VQuad™ software is used to automatically send and record voice files from four different types of network. VQuad™ supports up to 8 telephony devices simultaneously. A minimum of two telephony nodes are required for transferring files and these nodes may be configured at the same time on a single PC, or with each node served by one PC."

He added, "GL's VQuad™ along with the Voice Quality Testing, Echo Measurement Utility, Voice Band Analyzer & Data Test applications allows end-to-end intrusive testing for voice, data and video quality, echo, noise, call failure rates, and other impairments between and within different networks. The system is designed for easier, portable, and convenient testing. The system provides all necessary capability for automatic measurement of Voice Quality and QOS for any desired network including Wireless, VoIP (Voice over Internet Protocol), Analog, and TDM."

Mr. Bichefsky furthermore explained, "The VQuad™ - using a Dual Universal Telephone Adapter provides multiple interfaces for connecting to the Network using a single box solution. Dual UTA is a low power USB device that has been fully tested with an ultra-portable Dual Core NetBook, which allows both the VQuad™ and VQT to reside and operate simultaneously on the same NetBook.

A GPS sync port on the Dual UTA permits precise synchronization of sending and receiving audio functions, one-way delay, and round trip delay. The Dual UTA can be directed to automatically send and record sample voice files between nodes of a telephony network.

VQuad™ supports Data Testing including TCP, UDP, VoIP, Route, HTTP, FTP, DNS and SMS. The Data Tests are configured via the VQuad™ scripting and support the PC Ethernet connection or mobile device. VQuad™ with Dual UTA supports Fax testing up to 4 independent and simultaneous T.30 faxes."

Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP 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 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.
