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

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

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 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!

Barry Castle
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
– EU: Direct contact with DGIV, DGXIII and DGIII
– Progress Reports to Official bodies
– Reporting on Liaisons with industry consortia, ETSI internal
Liaison and with other Standards Bodies
– Participation in ECommerce and SME initiatives
– Meetings in USA and Asia/Pacific
David Gurle

TIPHON - Liaison activities
Avoid overlapping and assure a complete coverage of
the area: technically and geographically
– Within ETSI:
» Technical Committees: Network Aspects, Special Mobile Group,
Signaling, Switching and Protocols
» ETSI Projects on Terminals: Multimedia, Digital
– Outside ETSI:
» ITU-T
» IETF
» IMTC, VoIP Forum
» EURESCOM
