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 Gurle 8

TIPHON - Scope Initial focus on voice communications 3 phases: – Phase 1 (until end of 1997): Voice communication from an IPbased 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 Gurle 10

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 IPv 4/v 6 addresses David Gurle 11

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!
