Overview

SIST ETS 300 260 E2:2005 defines technical specifications, functional models, and information flows for the Call Transfer Supplementary Service (SS-CT) in Private Integrated Services Networks (PISN). Issued by the Slovenski Inštitut za Standardizacijo (SIST), this European Telecommunication Standard (ETS) ensures interoperability and standardized service functionality within private telecommunication systems. It aligns with the international framework as specified in ISO/IEC 13865 (1995), with modifications relevant for European implementations.

The standard provides a structured framework for implementing the call transfer supplementary service across multiple basic services offered by PISNs, built on ISDN (Integrated Services Digital Network) and OSI (Open Systems Interconnection) principles.

Key Topics

• Call Transfer Supplementary Service (SS-CT): Defines mechanisms and information exchanges required to enable the transfer of an active call from one user to another within a PISN, including both attended and unattended transfer scenarios.
• Specification and Functional Models: Outlines requirements for service components, signaling procedures, and state transitions to ensure proper function and user experience during call transfer events.
• Information Flows: Details the required message and data exchanges between PISN network elements, ensuring seamless call transfer operations.
• Normative References: Relies on related standards such as ETS 300 171, ETS 300 237, ETS 300 387, ETS 300 475-1, and others for definitions, signaling, and protocol requirements.
• Compatibility and Modifications: Incorporates necessary adaptations from the referenced international standard (ISO/IEC 13865), specifying updates in terminology and table content to ensure compliance with European system requirements.

Applications

The proper implementation of SIST ETS 300 260 E2:2005 enhances the flexibility and efficiency of private telecommunications infrastructures, especially in business and organizational environments that depend on robust internal voice services:

• Enterprise Telephony: Enables smooth call management, allowing employees to transfer calls between extensions or departments, boosting productivity and customer satisfaction.
• Contact Centers: Facilitates efficient handling of incoming calls, allowing agents to redirect inquiries to appropriate specialists without disconnecting the caller.
• Healthcare, Hospitality, and Education: Supports environments where effective and reliable internal communications are critical to operations, such as hospitals, hotels, and campus networks.
• PISN Operators and Equipment Vendors: Provides clear requirements for network designers, integrators, and manufacturers to achieve compliant implementations and facilitate interoperability among diverse systems.

By adhering to this standard, organizations ensure that their internal telecommunication services support consistent and expected call transfer behavior, fostering seamless communication and service reliability.

Related Standards

SIST ETS 300 260 E2:2005 is part of a suite of standards addressing PISN services and protocols:

• ETS 300 171: Specification, functional models, and information flows for circuit mode basic services in private telecommunication networks.
• ETS 300 173 / ETS 300 237: Define supplementary identification and name identification services.
• ETS 300 387: Method for specifying basic and supplementary services in PTN.
• ETS 300 475-1: Reference configurations for PTN exchanges.
• ISO/IEC 13865: International foundation for call transfer supplementary services, referenced and modified for European application.

Organizations seeking comprehensive standardization of private network services should reference these documents for holistic compliance and optimized network function.

Foreword
This second edition European Telecommunication Standard (ETS) has been produced by the
Communication, Networks, and Systems Interconnection Technical Committee (TC32) of ECMA on behalf
of its members and those of the European Telecommunications Standards Institute (ETSI).
This ETS is one of a series of standards defining services and signalling protocols applicable to Private
Integrated Services Networks (PISN). The series uses the Integrated Services Digital Network (ISDN)
concepts as developed by ITU-T and conforms to the framework of standards for Open Systems
Interconnection (OSI) as defined by ISO/IEC.
This particular ETS specifies the Call Transfer supplementary service.
The previous (first) edition of this ETS contained a "standalone" specification of these supplementary
services. This edition endorses an International Standard, ISO/IEC 13865, published since the publication
of the first edition of this ETS.
Transposition dates
Date of adoption of this ETS (doa): 31 May 1996
Date of latest announcement of this ETS (doa): 31 August 1996
