GL Communications Inc. conveyed today the availability of its VQuad™ (Voice Quad) software – Voice Quality Testing Across All Networks.

The VQuad™ software

The VQuad™ software is used to automatically send and record voice files from four different types of network (Quad meaning 4 networks: Wireless, VoIP, TDM, & Analog). VQuad™ supports up to 8 telephony devices simultaneously.

GL Communications Inc. a leader in providing PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, conveyed today the availability of its VQuad™ (Voice Quad) software – Voice Quality Testing Across All Networks.

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 (Quad meaning 4 networks: Wireless, VoIP, TDM, & Analog). 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 together on a single PC, or with each node served by one PC.”

He added, “GL's VQuad™ along with the Voice Quality Testing (VQT), Echo Measurement Utility (EMU), Voice Band Analyzer (VBA) & 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 (Bluetooth®, Wi-fi, 3G, 4G, LTE), VoIP, Analog, and TDM.”

Mr. Bichefsky further explained, “The VQuad™ - using a Dual Universal Telephone Adapter (Dual UTA) 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 (no external power required), 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 (OWD), and round trip delay (RTD). 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 (wired, WiFi, Broadband 3G/4G) or mobile device. VQuad™ with Dual UTA (VQT270) supports Fax testing (sending and receiving) up to 4 independent and simultaneous T.30 faxes.”

Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.

GL’s TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, OC-12, STM-1, STM-4, analog four-wire, and analog two-wire interface cards, external portable pods, and complete system solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303, Frame Relay, HDLC, V5.X, ATM, GSM, GPRS, LTE, etc.), and with capacities up to thousands of channels. Our newest products provide astonishing capacity and capture capability up to and including gigabit speeds.

GL’s VoIP and IP products generate / analyze thousands of calls and traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax. Almost 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 also 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 (VQT) product line complements all of GL's products. Using ITU-standard algorithms (PAMS, PSQM, and PESQ), GL's VQT provides a widely accepted solution for assessing voice quality in the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, OC-12, VoIP, Wireless, and Landline) 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.

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 such 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.
