SIST-V ETSI/EG 201 847 V1.1.1:2003

Overview

SIST-V ETSI/EG 201 847 V1.1.1:2003 is a standard developed by the Slovenian Institute for Standardization (SIST) in cooperation with ETSI. It specifies the guidelines for the operation of the Bearer Independent Call Control (BICC) protocol alongside the Digital Subscriber Signalling System No. 2 (DSS2) protocol. This document acts as a national supplement to the ITU-T Recommendation Q.1901, reflecting modifications for local endorsements and interoperability within digital telecommunications networks, particularly those supporting ATM and broadband ISDN technologies.

Key Topics

• Bearer Independent Call Control (BICC): A signalling protocol designed for the efficient and flexible establishment of calls independent of the bearer's physical characteristics, allowing seamless support for various transmission technologies such as ATM, IP, or TDM.
• Digital Subscriber Signalling System No. 2 (DSS2): A protocol used for broadband user-network interface signalling, primarily in B-ISDN environments, ensuring reliable communication for voice, video, and data services.
• Protocol Mapping: This standard addresses the mapping required to coordinate BICC with DSS2, with particular attention to AAL type 1 trunking, enabling interoperability between signalling and bearer technologies.
• Endorsement and Modifications: It incorporates and modifies elements from ITU-T Q.1901 and related technical reports, ensuring relevance and practical compatibility with European and Slovenian telecommunications infrastructure.
• Reference and Substitution: The document provides clear guidelines on reference substitutions and harmonization of protocol references for practical implementation.

Applications

SIST-V ETSI/EG 201 847 V1.1.1:2003 serves significant roles in the telecommunications industry, especially in environments requiring high integration between signalling systems and bearer technologies:

• Network Operators: Supports the deployment and upgrade of multiservice switching networks by ensuring compatibility between BICC and DSS2, crucial for modern converged networks.
• Equipment Manufacturers: Provides technical guidance for designing network hardware and software that supports both BICC and DSS2 protocols, essential for broadband ISDN and next-generation voice transport solutions.
• Service Providers: Ensures smooth interoperability and migration paths between legacy TDM and modern packet-based networks, essential for offering consistent voice and multimedia services.
• Standards Compliance: Facilitates conformity assessment and quality assurance for telecom products and network implementations within Europe, helping operators meet regulatory and technical requirements.
