Gaithersburg, MD (Vocus) September 24, 2009
GL Communications Inc., announced today the release of its latest VQuad™ Software with Dual UTA Hardware product. Disclosing the news to press persons, Mr. Robert Bichefsky, senior manager said, “VQuad™ software combined with new Dual UTA hardware makes connection and analysis to any network (VoIP, 2Wire, T1 E1, and Mobile) easier, less cluttered, and more versatile than ever before. The one platform now:
•integrates many outboard features of the older single UTA,
•doubles the number of simultaneous interfaces,
•adds GPS accuracy and synchronization,
•adds dual Bluetooth interfaces,
•adds features such as RTD, OWD (one way delay) and many others,
•and ultimately simplifies voice quality testing across all networks
•low power USB hardware, no external power required, compatible with NetBooks
He added, “The single platform provides the means of sending and receiving speech signals through various network interfaces including Wireless, VoIP, 2 Wire analog (PSTN), and TDM (T1 E1). VQT software then analyzes the transmissions using ITU standard algorithms, PESQ, PAMS, and PSQM. Measurements are provided for Mean Opinion Score (MOS), speech level, noise level, echo, and other distortions common to voice transmissions. In addition features are provided for easy automatic, remote, and repetitive runs”.
Mr. Bichefsky further added, “Additional analytical measurements can be provided with GL’s Voice Band Analyzer (VBA) for echo, activity factor, and other voiceband parameters. Round Trip Delay and One Way
Delay measurements are provided directly by the Dual UTA hardware”.
•PDD (Post Dial Delay) measurements for all interfaces
•Caller ID detection and display
•Enhanced scripting and remote operation
•Ability to inject impairments
•Full monitoring capability
•Automated PTT (Push-to-Talk) functionality for military / mobile radios
About GL Communications Inc.
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 TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, STM-1, 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, etc.), and with capacities up to thousands of channels.
GL’s VoIP and IP products generate / analyze thousands of calls / traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax using G.711, G.729, AMR, EVRC, GSM and a range of other codecs. 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 excepted solution across the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, VoIP, Wireless, and Landline) are all available.
GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA and UMTS 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 compliance testing per G.168 and G.160 across TDM, IP, VoIP and Wireless networks. 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.
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 almost 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 intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
