Project Objectives

• 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


3/20

Why TIPHON?

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


4/20

Working Principles

Have principles that foster an atmosphere ofcooperation 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


5/20

Existing standards as a basis

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


6/20

Interoperability of H.323 terminals

Packet Based Network

Scope of H.323

(Note)

Note: A gateway may support one or more of the GSTN, N-ISDN and/or B-ISDN connections.

Project Structure

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


15/20

Status

• 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


16/20

TIPHON NetMediatrix (CAN)


17/20

Relationship with other bodies

• 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


18/20

Marketing activitiesGoals• 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


19/20

Conclusions

• 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?
