David Gurle8 TIHPON - Goals Main objective –Combine telecommunications and Internet technologies to enable voice communications over IP-based networks to work with existing PSTN/ISDN/GSM networks Philosophy –to create a competitive environment which allows to produce specifications with a global acceptance

David Gurle9 Extensive use of EDH Openness to contributions world-wide Open to IP and telecom industry Focussed on a specific topic Short time schedules, frequent meetings TIPHON - Working Methods

David Gurle10 TIPHON - Scope Initial focus on voice communications 3 phases: –Phase 1 (until end of 1997): Voice communication from an IP- based terminal to PSTN/ISDN/GSM handset –Phase 2 (until June 1998) : Voice communication from PSTN/ISDN/GSM hand set to IP-based terminals –Phase 3 (until December 1998): Voice communications from PSTN/ISDN/GSM handsets to PSTN/ISDN/GSM handsets using an intermediary IP-based network

David Gurle11 TIPHON - Technical Objectives –define set of requirements for service interoperability; –identify reference configurations, interfaces and functional models (gateway) –specify call control procedures, information flows and protocols; –standardize address translation between E.164 and IPv4/v6 addresses

David Gurle12 TIPHON - Technical Objectives (…) –specify technical aspects of charging/billing –specify technical aspects of security –define end-to-end quality of service parameters, including transcoding and echo-cancellation –implement and build demonstrating environment for TIPHON based products, the TIPHON Net!
