SIST ETS 300 298-2 E2:2003

Overview

The SIST ETS 300 298-2 E2:2003 standard defines specifications for the Broadband Integrated Services Digital Network (B-ISDN), focusing on the Asynchronous Transfer Mode (ATM) layer. As the second part in a series, this standard aligns with ITU-T Recommendation I.361 (1995) and addresses vital updates regarding ATM cell structure and header functions. Developed by the Slovenski inštitut za standardizacijo (SIST), this standard is harmonized with the European Telecommunications Standards Institute (ETSI) and supports the robust development of broadband communications networks across Europe.

Key Topics

SIST ETS 300 298-2 E2:2003 addresses the following key areas:

• ATM Cell Structure: Details updated definitions and specifications for the structure of ATM cells, supporting efficient and standardized broadband data transmission.
• ATM Header Functions: Specifies the functionality and assignment of header fields within ATM cells, crucial for accurate routing and flow control in B-ISDN networks.
• Virtual Channel Identifier (VCI) Handling: Defines procedures for handling reserved VCI values and their transmission within Virtual Path Connections (VPC).
• Generic Flow Control (GFC) Procedures: Describes GFC protocol procedures at critical interface reference points, allowing for simplified and effective traffic management between network segments.
• Compatibility and Harmonization: Ensures alignment with the ITU-T I.361 recommendation, which facilitates interoperability and consistency across international broadband networks.
