  • The first NGN-VoIP Interop event

    1. 1. <ul><li>The first NGN-VoIP Interop event </li></ul><ul><li>29 november to 3 december 2004, ETSI, France </li></ul>
    2. 2. What is ETSI? ETSI (the European Telecommunications Standards Institute) is a non profit organization whose mission is to produce the telecommunications standards that will be used for decades to come  throughout Europe and beyond. Based in Sophia Antipolis , south of France, ETSI unites 786 members from 56 countries inside and outside Europe, and represents administrations, network operators, manufacturers, service providers, research bodies and users. ETSI's activities are maintained in close alignment with the market needs expressed by its members. ETSI plays a major role in developing a wide range of standards and other technical documentation as Europe's contribution to world-wide standardization in telecommunications ETSI is officially recognized by the European Commission and the EFTA secretariat
    3. 3. The ETSI interoperability service: a new permanent service since end 2000. <ul><li>Experiment in the period ’99 – 2000 the interest to complement the standardisation works using regular meetings by the organisation of « bake-offs » where participants bring implementations/products; </li></ul><ul><li>Confirm at the GA 35, nov. 2000, the interest of such service and create a permanent one: the ETSI Interoperability Service; </li></ul><ul><li>July 2001: change the name « bake-off » , a trade-mark of Pillsbury by « Plugtests » </li></ul><ul><li>Begining 2004, 600 companies sent about 2000 engineers to 40 interoperability events </li></ul>

    9. 9. Introduction <ul><li>Starting from the TIPHON project and since the NGN Starter Group report during the GA38, ETSI wants to play a major role in the standardization of the VoIP technologies. </li></ul><ul><li>This first VoIP Access and Speech quality Interop is a good opportunity for ETSI to increase its presence in the NGN standardization process. </li></ul><ul><li>The idea of the event is to invite different actors of VoIP at ETSI, to test interoperability of solutions and interworking between different protocols and networks. </li></ul><ul><li>During the Interop event, ETSI will provide the participants with rooms, Ethernet and Wireless networks, PSTN Accesses, as well as its usual Interop support, like Scheduling and specific expertise on VoIP. </li></ul><ul><li>Furthermore, the availability of test tools provider, with their test solutions will help manufacturer in finding and resolving technical issues, as well as performing conformance test cases and Speech quality measurements. </li></ul>
    10. 10.
