GL Announces Voice Feature Testing For Next Generation Networks
GL Communications Inc. announced today the release of its latest Voice Feature Testing Application For Next Generation Networks.
- (1888PressRelease) February 15, 2013 - Gaithersburg, Maryland, USA -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.
In many cases, these features involve detection and generation of tones and dual tones with varying cadences. Testing such features cannot be performed with standard Bulk Call Generators / Receivers. In fact, signal processing functions are required to fully test these features. In the future, the residence architecture for voice is more likely to be 4 wire SIP based WiFi phones or 3G/4G phones with higher quality audio. In either case, voice feature testing will become even more important."
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.

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."
