Foreword
This Technical Specification (TS) has been produced by ETSI Project Telecommunications and Internet Protocol
Harmonization Over Networks (TIPHON).
The functions needed to provide a service application and its constituent Service Capabilities may be replicated in a
number of domains that are interconnected to provide, for instance, a call.
Service capabilities are indivisible units of interoperability between TIPHON systems. Using known Service
Capabilities, interconnection agreements can specify the Service Capabilities for which the agreement holds.
Service providers and equipment vendors can add value to service capabilities by enhancing them in their networks and
equipment beyond the functionality defined by the standardized definition without adversely impacting interoperability.
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 inter-work with existing PSTN services while enabling more advanced services to be subsequently
developed.
Figure 1 shows the relationship of the present document with other TIPHON release 3 deliverables.

1 Scope
The present document forms part of TIPHON Release 3 and defines a set of Service Capabilities for the support of
simple call service applications.
Service Capabilities are indivisible technical functions that are used to support service applications. They are defined
from a technical perspective as technical functions and not from a user's perspective as service elements.
The Service Capabilities and their attributes have been defined so that they are capable of supporting a telephony simple
call service application that is compatible with telephony as standardized in ETSI for PSTN and ISDN.
Subsets of the service capabilities defined here can be selected for implementation in equipment and networks to
support particular service applications.
The service capabilities defined here may also be used for the support of service applications other than simple call.
TR 101 835 [8] provides details of the steps involved in a TIPHON release.
