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

9
TIPHON - Working Methods

• 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

10
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

11
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

12
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!
