Overview
SIST EN 300 356-12 V3.1.3:2003 focuses on the Integrated Services Digital Network (ISDN), specifically the use of Signalling System No.7 (SS7) and the ISDN User Part (ISUP) version 3 for international interconnection. This standard defines procedures and protocols for the Conference Call, Add-on (CONF) supplementary service, aligning with the modified ITU-T Recommendation Q.734. It outlines additional generic protocol functions required beyond the basic call handling to facilitate multi-party conference call services across public telecommunications networks in Europe.
This document details the stage three (protocol and switching functions) requirements necessary for implementing the conference call add-on service on ISDN systems using ISUP, supporting interoperability for speech services across international ISDN gateways.
Key Topics
- Conference Call, Add-on (CONF) Supplementary Service: Enables multiple parties to participate in a single call, extending the regular call functionality with conference capabilities.
- Protocol Procedures: Defines the signalling protocols and message handling required at international ISDN interfaces to establish, modify, and terminate conference calls.
- International ISDN Interconnection: Specifies requirements for exchanges at international gateways, ensuring consistent handling of conference services across borders.
- Modifications to ITU-T Q.734: Incorporates agreed changes for European implementation, referencing relevant ETSI standards and documentation.
- Applicability: Targets services carrying speech and is intended for use in networks operated by European public telecommunications providers.
- Compatibility and Interworking: Provides recommendations for ensuring that conference call signalling remains compatible between networks, including parameter coding and notification handling.
Applications
SIST EN 300 356-12 V3.1.3:2003 is vital for organizations that:
- Operate or Design ISDN Equipment: Vendors providing switches, gateways, or network equipment for pan-European ISDN networks must implement the supplementary procedures described.
- Telecommunication Service Providers: Essential for service providers enabling international conference call services over SS7 ISUP, ensuring seamless supplementary service delivery across national and international ISDNs.
- Network Integrators and Test Labs: Important in testing scenarios involving multi-party conference calls, helping verify protocol conformance and interoperability.
- Standards Compliance: Provides a reference point for compliance with European ISDN and SS7 protocol requirements, minimizing service inconsistencies for end users.
Use cases include:
- Enterprise communication systems requiring reliable multi-party conferencing.
- Carrier networks bridging international business calls where conference capability is critical.
- Public sector and emergency response systems needing robust, standards-based conference call functionality.
