Overview
SIST EN 300 771-1 V2.0.1:2005 defines the protocol specification for point-to-multipoint call and bearer control at the B-ISDN user-network interface, using the Digital Subscriber Signalling System No. two (DSS2) protocol. The standard aligns with ITU-T Recommendation Q.2971 (1995), with specific amendments endorsed by ETSI to ensure compatibility and conformance for broadband integrated services digital networks (B-ISDN).
Supporting on-demand, connection-oriented point-to-multipoint communications, this standard is a key reference for telecommunications services within the European and global B-ISDN framework. It specifies the essential layer 3 protocol procedures and switching functions needed to deliver basic telecommunications services at the TB reference point, which connects user premises equipment to the public B-ISDN.
Key Topics
- Point-to-multipoint call/bearer control: Specifies the procedures for establishing, managing, and releasing connections where one source communicates with multiple destinations across a B-ISDN.
- Layer 3 protocol specification: Details message flows and required negotiation for DSS2 at the user-network interface, supporting efficient and standardized communication.
- Compatibility with ITU-T standards: Incorporates amendments from ITU-T Q.2971, ensuring compliance with international recommendations and harmonization of European and global implementations.
- Support for supplementary services: Establishes a framework for adding features such as multiple subscriber numbers, calling line identification, and closed user group, through seamless protocol integration.
- Conformance and testing: Part of a broader ETSI series, this standard provides a base for additional parts covering protocol conformance testing and supplementary services.
Applications
The practical value of SIST EN 300 771-1 V2.0.1:2005 is centered on ensuring interoperability, reliability, and scalability in broadband telecommunication networks:
- Telecommunications network providers: Enables consistent implementation of user-network interfaces for B-ISDN services, reducing complexity in network deployment and ensuring smooth interconnection between different vendors’ systems.
- Equipment manufacturers: Assures product compliance with recognized standards, promoting compatibility and simplifying certification processes for B-ISDN access devices integrating DSS2 signaling protocols.
- Private and public B-ISDN access: Supports service providers and enterprises in deploying large-scale, multi-user broadband communication solutions, such as virtual private networks (VPN), multimedia conferencing, and advanced voice/data services.
- Supplementary service integration: Facilitates the development and deployment of value-added telecommunications features without deviating from standard protocol behaviors.
Related Standards
When implementing SIST EN 300 771-1 V2.0.1:2005, the following standards provide complementary specifications and extended application support:
- ITU-T Recommendation Q.2971: Original baseline for point-to-multipoint call/bearer control protocol in B-ISDN.
- ETSI EN 300 443-1: Layer 3 specification for basic call/bearer control using DSS2 at the B-ISDN user-network interface.
- ETSI EN 300 437-1: Service Specific Co-ordination Function (SSCF) for ATM Adaptation Layer signaling at the UNI.
- ETSI EN 300 661-1 to EN 300 668-1: Protocols for supplementary services, including direct dialing in, multiple subscriber numbers, line identification services, and user-to-user signaling.
- ETSI EN 300 770-1: Closed user group (CUG) supplementary service protocol specification.
By adhering to SIST EN 300 771-1 V2.0.1:2005, organizations can ensure robust, standards-based B-ISDN implementations that enable reliable and scalable point-to-multipoint broadband services across diverse network environments.
