Foreword
This Technical Specification (TS) has been produced by ETSI Project Telecommunications and Internet Protocol
Harmonization Over Networks (TIPHON).
Introduction
The approach being taken to standardization in TIPHON represents a departure from that used in the past for PSTN,
ISDN and GSM. Its aim is to allow much greater scope for competition through innovation in the design of equipment
and services. Its aim is also to provide adequate standardization to facilitate the operation of services across
interconnected networks, even networks that use different technologies. The present document presents the initial core
set of Service Capabilities envisaged to be required to enable service providers to offer services on TIPHON networks
that may safely interwork with existing PSTN services while enabling more advanced services to be subsequently
developed.

1 Scope
The present document describes how the H.323 protocol suite can be used to implement the architecture, defined in
TS 101 314 [8] and the primitives, information elements and behaviours, defined in TS 101 882.
The present document defines the mapping of the following meta-protocols:
• the Registration meta-protocol;
• the Bearer Control meta-protocol; and
• the Call Control meta-protocol.
The document is applicable to equipment performing the roles of terminal, gateway, gatekeeper and also to entities
within the IP network that are necessary to support TIPHON Release 3.
The H.323 profile contained in the present document was derived by examination of:
• ITU-T Recommendation H.323 [10] and associated suite of protocols:
- H.225.0 (RAS and Q.931); and
- H.2
