Overview

SIST ETS 300 258 E2:2005 is a European Telecommunication Standard developed by the Slovenski inštitut za standardizacijo (SIST) and based on ETSI work. This standard specifies the Path Replacement Additional Network Feature (ANF-PR) for Private Integrated Services Networks (PISN). The purpose of this feature is to improve network efficiency and service continuity by enabling the dynamic replacement of the call path within a PISN when certain conditions are met.

This standard is closely aligned with ISO/IEC 13863 (1995), with specific modifications for European telecommunications environments. Path Replacement is one of several additional network features designed to enhance service in PISNs, which are enterprise-level networks supporting advanced telephony and data communication services, following the Integrated Services Digital Network (ISDN) and Open Systems Interconnection (OSI) frameworks.

Key Topics

• Path Replacement (ANF-PR): Defines the mechanisms and functional models for replacing an established connection path within a PISN without disrupting ongoing services.
• PISN Architecture: Describes the functional components and interfaces involved in private integrated communications systems, supporting both voice and data.
• Specification and Information Flows: Details the modeling and signaling protocols necessary for implementing path replacement, addressing how information is exchanged and actions are coordinated across network elements.
• Modification of International References: Includes tailored adjustments to references and terminology (e.g., replacing certain ISO/IEC and CCITT references with European standards) for compatibility and regional compliance.

Applications

The Path Replacement additional network feature provides practical value in several key scenarios within enterprise telecommunications:

• Dynamic Rerouting: Enables organizations to optimize network resource usage, rerouting active calls when more efficient paths become available or when existing circuits need to be released for higher-priority traffic.
• Service Continuity: Supports seamless communication by allowing underlying network changes without interrupting in-progress sessions, which is critical for businesses relying on uninterrupted voice and data services.
• Resource Optimization: Reduces congestion and improves performance in complex PISN environments, especially when integrating geographically dispersed locations with high traffic volumes.
• Enhanced Private Network Management: Facilitates more flexible management of internal telephony and data communications, leading to more robust business operations and disaster recovery options.

Organizations that implement PISN architectures, such as large enterprises, governmental agencies, and institutions with multiple sites, greatly benefit from the additional resilience and control provided by the ANF-PR.

Related Standards

SIST ETS 300 258 E2:2005 is part of a comprehensive framework surrounding private communications networks. Relevant related standards include:

• ISO/IEC 13863 (1995), modified: The international reference for the path replacement feature, upon which this standard is based.
• ETS 300 171: Specification, functional models, and information flows for control aspects of circuit mode basic services in private telecommunication networks.
• ETS 300 189: Addressing in private telecommunication networks, supporting the routing and management of calls.
• ETS 300 387: Methods for the specification of basic and supplementary services, offering guidance on service design and integration.
• ETS 300 475-1: Reference configurations for private network exchanges, specifying network architecture components.

All these standards support the sophisticated implementation and ongoing evolution of Private Integrated Services Networks (PISN) in line with best practices for European telecommunication networks and global ISDN/OSI frameworks.

Page 2ETS 300 258: May 1996ForewordThis second edition European Telecommunication Standard (ETS) has been produced by theCommunication, Networks, and Systems Interconnection Technical Committee (TC32) of ECMA on behalfof its members and those of the European Telecommunications Standards Institute (ETSI).This ETS is one of a series of standards defining services and signalling protocols applicable to PrivateIntegrated Services Networks (PISN). The series uses the Integrated Services Digital Network (ISDN)concepts as developed by ITU-T and conforms to the framework of standards for Open SystemsInterconnection (OSI) as defined by ISO/IEC.This particular ETS specifies the Path Replacement additional network feature.The previous (first) edition of this ETS contained a "standalone" specification of these additional networkfeatures. This edition endorses an International Standard, ISO/IEC 13863, published since the publicationof the first edition of this ETS.Transposition datesDate of adoption of this ETS (doa):31 May 1996Date of latest an
