Overview
SIST EN 300 356-14 V4.2.1:2004 is a European standard that defines the stage three specifications for the Explicit Call Transfer (ECT) supplementary service within the Integrated Services Digital Network (ISDN) environment, using the Signalling System No.7 (SS7) ISDN User Part (ISUP) protocol (version 4) for international telecommunications interfaces. Developed by the Slovenian Institute for Standardization (SIST) and endorsed by ETSI, this standard aligns with ITU-T Recommendation Q.732, clause 7 (1996), including selected modifications and implementors’ guidelines.
This standard facilitates interoperability and consistent implementation of ECT supplementary services across European public telecommunications operators, supporting the seamless integration of ISDN services in international networks.
Key Topics
- Explicit Call Transfer (ECT) Supplementary Service:
Details the requirements for enabling a user to transfer two calls-either incoming or outgoing-into a single connected call. - Protocol and Switching Functions:
Specifies procedures for signalling and switching in ISUP v4 as needed to support ECT on international links. - International Interface Requirements:
Focuses on interoperability for international ISDN interconnections, ensuring compatibility between national and international signalling protocols. - Service Stages:
- Stage 1: Service description from the user’s perspective
- Stage 2: Functional capabilities and information flows
- Stage 3: Protocols and switching needed for implementation (detailed in this standard)
- Coding and Compatibility Information:
Provides guidelines for the encoding of parameters and messages for optimal compatibility between equipment and operators. - Reference Modifications:
Incorporates corrections and clarifications to ITU-T references for European usage, ensuring alignment with other EN standards.
Applications
- International Telephony Operators:
Critical for operators who deploy ISDN services over SS7 signalling networks, enabling advanced call control features such as explicit call transfer between international parties. - Network Equipment Manufacturers:
Guides the development and testing of switches and signalling gateways to support ECT and related supplementary services in accordance with European and ITU-T standards. - Conformance and Interoperability Testing:
Provides a technical basis for protocol conformance evaluation, ensuring equipment and networks can interoperate reliably across borders. - Public and Private ISDN Deployment:
Applicable to both public telecommunication networks and large-scale private networks that leverage ISDN for advanced voice services.
