Overview
SIST EN 300 356-8 V3.1.3:2003 is a European standard developed by the Slovenian Institute for Standardization (SIST) and based on EN 300 356-8. It specifies the Stage 3 procedures for the User-to-User Signalling (UUS) supplementary service within the Integrated Services Digital Network (ISDN) context, utilizing Signalling System No.7 (SS7); ISDN User Part (ISUP) version 3 for international interfaces. This document modifies and aligns with the ITU-T Recommendation Q.737, clause 1 (1997), providing additional generic procedures beyond the basic call to enable direct information transfer between ISDN users.
The UUS supplementary service lets ISDN subscribers exchange a limited amount of information over the signalling channel during a call. This function is critical for supporting enhanced communication and interoperability in public European telecommunications networks.
Key Topics
User-to-User Signalling (UUS):
- Enables the transmission of user information between two ISDN users during call setup or active calls.
- Information is exchanged over the signalling channel, not affecting the main voice channel.
Scope and Applicability:
- Focuses on procedures for international ISDN interconnections via SS7/ISUP version 3.
- Includes formatting, coding of messages, and actions at originating and destination exchanges.
- Applies solely to international interfaces; national implementations may require separate considerations.
Protocol Procedures:
- Defines how switching functions and protocol elements interact to deliver the UUS supplementary service.
- Addresses compatibility and interworking between networks supporting or not supporting UUS.
Service Transparency:
- Ensures that supplementary user information is reliably transmitted without affecting the core call.
- Stipulates rejection and compatibility handling when the service is unsupported.
Standards Alignment:
- All references are updated to reflect ETSI and SIST adaptations of ITU-T base recommendations.
Applications
The SIST EN 300 356-8 V3.1.3:2003 standard is utilized in a variety of real-world telecommunications scenarios, including:
Enhanced ISDN Services:
- Telecommunication operators provide value-added services such as call-based information exchange, improved customer interactions, and custom signaling between business users.
Inter-network Communication:
- Essential for carriers operating at international gateways, facilitating seamless integration between national and international ISDN networks.
Support for Supplementary Services:
- Forms the basis for delivery of services where exchanging brief user messages or authentication information during or before a connection is required.
Business and Enterprise Telephony:
- Used by enterprises relying on ISDN for secure, flexible signaling to transfer control data alongside voice or data calls.

Practical Value
Implementing SIST EN 300 356-8 V3.1.3:2003 ensures that ISDN networks effectively support the User-to-User Signalling (UUS) supplementary service across borders, enhancing interoperability and enabling advanced telecommunications solutions for both public and private sector communications solutions. This standard is essential for engineers, network designers, and telecommunication service providers seeking to deliver robust and standards-compliant ISDN-based services.
