Overview
SIST EN 300 356-12 V4.2.1:2004 defines the protocol and procedures for implementing the Conference Call, add-on (CONF) supplementary service under the Integrated Services Digital Network (ISDN) using ISDN User Part (ISUP) version 4 at the international interface. As part of the larger European Standard for ISDN Signalling System No.7 (SS7), this standard builds upon ITU-T Recommendation Q.734 (1993) and its implementors guide, with specific modifications for pan-European networks.
Developed by the Slovenian Institute for Standardization (SIST) and endorsed by ETSI, this document provides the technical specifications required to ensure reliable, interoperable conference calling capabilities across international ISDN networks, forming an essential aspect of telecommunication service integration.
Key Topics
- ISDN Conference Call Add-on Service: Details procedures for setting up, managing, and terminating conference calls involving multiple parties over ISDN, ensuring support for simultaneous multi-party communication.
- ISUP Version 4 Protocols: Defines the protocol message formats, codes, and network procedures necessary using ISUP v4 for international interfaces.
- SS7 Signalling Compliance: Specifies how the conference call service is achieved within the wider SS7 architecture, focusing on international interoperability.
- Network Interworking: Describes how the specified service interacts with national and international exchanges, including treatment of network-specific functions and format conventions.
- Modifications & Endorsements: Documents the specific changes and endorsements from ITU-T Q.734 to align with European network requirements under ETSI guidelines.
Applications
The CONF supplementary service supports scenarios where real-time voice communication between more than two participants is required, leveraging the robustness and reach of ISDN and SS7. Key practical applications include:
- Enterprise Conferencing: Businesses conducting internal and international teleconferences benefit from standardized multi-party call setup and management.
- Public Telecommunication Services: Service providers deliver reliable group calling to customers across countries, enabled by consistent signalling and network behavior.
- Network Equipment Design: Manufacturers of PBXs, switches, and ISDN-enabled devices use these protocols to ensure product compatibility for international deployment.
- Inter-Carrier Operations: Telecommunications carriers and operators rely on the standard to assure seamless conference call services when interconnecting differing national ISDN networks at international gateways.
- Regulatory Compliance: Adherence ensures services meet the requirements of European telecommunications frameworks, reducing barriers for network expansion and service integration.
By using SIST EN 300 356-12 V4.2.1:2004, network operators and manufacturers can achieve interoperability, consistency, and reliability for ISDN-based conference call offerings, supporting both legacy infrastructure and evolving digital services.
