Overview
SIST EN 300 258 V1.3.1:2005 specifies the requirements for the Path Replacement additional network feature (ANF-PR) in Private Integrated Services Networks (PISN). Developed by the Slovenski inštitut za standardizacijo (SIST) and based on the European standard EN 300 258, this document provides a comprehensive functional model, specification, and description of information flows for path replacement within PISN environments. The standard is harmonized with the corresponding international standard ISO/IEC 13863 (with modifications), ensuring consistency across telecommunications and integrated digital networks worldwide.
Key Topics
- Private Integrated Services Network (PISN): Focuses on the management and enhancement of private telecommunication infrastructures that integrate multiple services such as voice, data, and video.
- Path Replacement (ANF-PR): Describes mechanisms for replacing an existing connection path within a network, which is essential for maintaining optimal communication, especially during changes in network topology or failures.
- Functional Model and Information Flows: Outlines how the path replacement feature operates within the PISN architecture, including the roles of network components and the necessary information exchanges.
- Compatibility and Interoperability: Ensures that implementation of ANF-PR aligns with relevant international standards to facilitate integration and migration across multi-vendor and multi-technology environments.
- Endorsement of ISO/IEC 13863: Provides guidance for national adoption, clearly identifying modifications made to the original international standard for regional applicability.
Applications
The ANF-PR feature defined in SIST EN 300 258 V1.3.1:2005 is crucial for organizations relying on Private Integrated Services Networks, particularly those requiring robust internal communication infrastructures. Key applications include:
- Dynamic Call Routing: Enables seamless rerouting of voice or data calls when network paths change, such as during maintenance, congestion, or failure events, minimizing service disruption.
- Network Upgrades and Maintenance: Supports businesses in upgrading their PISN infrastructures while maintaining connectivity, leading to improved network reliability and user experience.
- Business Continuity: Critical for institutions where uninterrupted communication is essential, including financial services, healthcare, and emergency operations.
- Multi-site Enterprises: Ideal for organizations with multiple locations that need to ensure persistent and flexible connections between sites through efficient path management.
Related Standards
SIST EN 300 258 V1.3.1:2005 references and aligns with several key international and European standards, enhancing its scope and ensuring technical compatibility:
- ISO/IEC 13863: The underlying international standard for the path replacement feature in PISN.
- ETSI EN 300 189: Specifies addressing within PISN, adapted from ISO/IEC 11571.
- ETSI EN 300 171: Addresses control aspects of circuit-mode basic services, based on ISO/IEC 11574.
- ETSI ETS 300 475-1: Reference configuration for private telecommunication networks, drawn from ISO/IEC 11579-1.
- ETSI ETS 300 387: Methodology for the specification of basic and supplementary telecommunication services.
By following the specifications detailed in SIST EN 300 258 V1.3.1:2005, network designers and managers can ensure their PISN systems are robust, interoperable, and compliant with international best practices, promoting network efficiency and business resilience across modern telecommunication environments.
