A Telecom and IP Project from ETSI

1. A Telecom and IP Project from ETSI Gerald Meyer gerald.meyer@oen.siemens.de

2. define a set of requirements for service interoperability reference configurations, interfaces and functional models call control procedures, information flows and protocols address translation between E.164 and IPv4/v6 addresses specify technical aspects of charging/billing specify technical aspects of security define end-to-end quality of service parameters implement and build demonstration environment for TIPHON based products Project Objectives

3. Because there are interoperability issues between voice applications using IP and SCN applications the technology behind voice over packet networks is not yet mature industry is looking for a common language interoperability speeds up market acceptance of a new technology there was a gap before the creation of TIPHON Why TIPHON?

4. Have principles that foster an atmosphere of cooperation leading to positive developments open to world-wide contributions from members andnon-ETSI members focused on a specific topic free availability of documents easy access to FTP short time schedules and frequent meetings Working Principles

5. H.323 Covers the technical requirements for multimedia communications systems in those situations where the underlying transport is a packet based network (PBN) which may not provide a guaranteed Quality of Service (QoS). Local area networks, enterprise area networks, metropolitan area networks, intra-networks, and inter-networks (including the Internet) They also include dial-up connections or point-to-point connections over the GSTN or ISDN Existing standards as a basis

13. Project plan

14. 6 Working Groups WG1 - Requirements for service interoperability WG2 - Architecture and reference configurations WG3 - Call control procedures WG4 - Naming, Addressing WG5 - End-to-End Quality of Service aspects WG6 - Verification and Demonstration Implementation Project Structure

15. Approved requirements for phase 1 Approved document on Naming, Addressing for phase 1 Document on Architecture approved at WG level for phase 1 Stable draft for phase 1 on quality of service and demonstrator configuration table of contents, scopes for phase 2 documents active co-operation with other bodies specialist task force support meeting schedule until end of 1998 Status

16. TIPHON Net

17. TIPHON widely accepted as globally operating body ITU-T SG 16 focussing on the multimedia terminal and security IETF defines a new signalling protocol, SIP, in SIPTEL IETF defines interoperability between web services and PSTN/ISDN in PINT IMTC VoIP Forum approved the interoperability agreement 1.0 between IP terminals Relationship with other bodies

18. Goals Obtain industry acceptance of our output Gain support from administrations and regulators Obtain support from other standards bodies Methods Press releases, press conferences, and interviews with key TIPHON officials Direct contact with DG IV, DG XIII, and DG III Progress reports to official bodies Meetings in USA and Asia/Pacific Marketing activities

19. Integration of voice and data traffic on IP basis is the future but there are interoperability and technology issues industry is committed to standards and is actively contributing standards bodies do not compete most of the issues should be solved by the end of 1988 but what about the regulatory matters?
