GL Announces Voice Feature Testing for Next Generation Networks


Gaithersburg, MD, February 17, 2013 --(PR.com)-- GL Communications Inc. announced today the release of its latest Voice Feature Testing Application for Next Generation Networks.

Speaking to reporters, Mr. Vijay Kulkarni CEO of the company said, “Next Generation Networks (NGNs) are based on broadband IP technology and are frequently promoted as 'triple play' offerings, especially for residential services providing voice, TV, and Internet. They freely offer advanced voice features that cost extra when provided by legacy circuit switched PSTN landlines. Since these software-based services are frequently enhanced, changed, or deleted, the features can be prone to 'upgrade issues.' Thus automated testing tools for regression and advanced feature testing can be of great value.”

He added, “In the residential case, because customers are still 'attached' to their home telephones, a desirable system that reuses the 'copper home wiring' and 2-Wire standard telephone sets is a necessary offering. Here, NGN advanced voice features are similar to but more sophisticated than CLASS (Custom Local Area Signaling Service) features PSTNs offer. These features include three way calling, call waiting, call hold, caller id, call waiting with caller id among others."

Mr. Kulkarni further added, “In the enterprise case, the common conduit for voice, data, and video is Ethernet with Internet Protocol (IP) for transport and signaling. Voice will use SIP phones and IP PBXs or Hosted IP PBXs in the Cloud. This architecture will evolve to fully integrate with the desktop and converge Email, SMS, IM, Voice, and other services. Test capability for higher quality voice (any codec support), inband and out-of-band digit transmission, and DSP are just some necessary functions.”

He added, “To test easily NGN voice features, in both residence and enterprise, GL has introduced a library of functional capabilities within its standard emulation software platform called MAPS™, or Message Automation and Protocol Simulation.

“MAPS™ is a versatile telecommunications protocol emulator. MAPS™ CAS and MAPS™ SIP are specific MAPS products that provide functional capabilities to test and verify voice features of NGNs. Using 'drag and drop' tools such as TestShell or scripting languages such as TCL, one can easily create compliance tests for simple to complex voice features.”

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, 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) are all 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.

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 characteristics. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
