Telecommunications and Internet Protocol Harmonization Over Networks (TIPHON) Release 3; Service Capability Definition; Service Capabilities for a Simple Call (V1.1.1)
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.
