SIST ETS 300 298-1 E2:2003

Overview

SIST ETS 300 298-1 E2:2003 defines critical aspects of the Broadband Integrated Services Digital Network (B-ISDN) using Asynchronous Transfer Mode (ATM) technology. Aligning with ITU-T Recommendation I.150 (1995), this standard focuses on the functional characteristics of the ATM layer in B-ISDN, providing essential definitions for ATM cell structure and header functions. Adopted by the Slovenian Institute for Standardization (SIST), this document harmonizes with the European ETSI standard, supporting interoperability and efficient deployment of broadband networks.

Key Topics

The standard covers a range of vital aspects for telecommunications professionals working with B-ISDN and ATM technology:

• ATM Cell Structure and Header Functions: Additional definitions and updates to the fundamental ATM cell format and associated header fields, ensuring precise routing and control information in high-speed networks.
• ATM Layer Specifications: Detailed requirements for the functional operation of the ATM layer, as necessitated by updates to the ITU-T I.150 recommendation.
• Routing Field and Virtual Channel Identifier (VCI): New specifications regarding the preassigned combinations of the routing field and the handling of reserved VCI values within a Virtual Path Connection (VPC).
• Generic Flow Control (GFC) Protocol: Specification of procedures to ensure effective flow control at network interfaces, specifically at the S and T reference points within the B-ISDN architecture.
• Compatibility and Interoperability: Guidelines to maintain compatibility with previous editions and to support interoperability between national and European standards for broadband digital communication.

Applications

SIST ETS 300 298-1 E2:2003 is essential for organizations and professionals involved in designing, implementing, and maintaining broadband ISDN infrastructure. Key application areas include:

• Telecommunication Network Deployment: Ensures standardized ATM functionality in new and existing B-ISDN infrastructures, supporting voice, data, and multimedia services over a unified digital network.
