Overview

SIST EN 301 258 V1.2.1:2005 is a Slovenian national standard that endorses the European Standard EN 301 258 V1.2.1, which is part of the telecommunications series for Private Integrated Services Networks (PISN). This standard specifically addresses the inter-exchange signalling protocol for the Recall supplementary service, aligning closely with ISO/IEC 15052 (2003), with modifications. Developed by the Slovenski inštitut za standardizacijo (SIST) and maintained in collaboration with the European Telecommunications Standards Institute (ETSI) and ECMA, it ensures coherent integration of recall services in digital private enterprise networks.

Key Topics

• Private Integrated Services Network (PISN): Focuses on enterprise-level telecommunication networks that combine voice, data, and supplementary services.
• Inter-exchange Signalling Protocol: Defines the procedures and protocols for signalling between PISN exchanges, particularly at the critical Q reference point.
• Recall Supplementary Service: Ensures that users can recall a previously established connection, improving communication flexibility and efficiency in PISN environments.
• Endorsement and Compatibility: This standard adopts and modifies content from ISO/IEC 15052, aligning with international best practices and ensuring compatibility with related standards such as QSIG and PSS1 protocols.
• Referenced Standards Integration: References multiple connected standards for basic circuit services, supplementary services, and reference configurations to support comprehensive PISN capabilities.

Applications

The Recalls supplementary service protocol described by SIST EN 301 258 V1.2.1:2005 is vital for organizations that:

• Operate Large or Multi-site Private Voice Networks: Including businesses, governmental organizations, and institutions requiring robust internal communications.
• Utilize Virtual Private Networks (VPN) for Telephony: The protocol supports flexible, feature-rich voice networks, integrating recall functions vital for call management.
• Demand Reliable Communication Features: The recall service enhances usability by allowing users to conveniently re-establish previous calls without re-dialing, supporting productivity and business continuity.
• Plan for International Expansion or Standardization: Adhering to ISO/IEC-aligned protocols ensures seamless interoperability with other standards-based infrastructure globally.

Related Standards

SIST EN 301 258 V1.2.1:2005 references and is closely connected to a suite of relevant telecommunications standards, including:

• EN 300 172: Circuit-mode basic services for PISN
• EN 300 239: Generic functional protocol for supplementary services
• EN 300 257: Call diversion supplementary service
• EN 300 260 & EN 300 261: Call transfer supplementary service
• EN 300 238: Name identification supplementary service
• EN 301 257: Recall supplementary service - specification and flows
• EN 301 265: Call interception Additional Network Feature (ANF)
• ISO/IEC 15052 (2003): Base international standard for recall supplementary service
• PSS1 (QSIG): Widely used protocol for PISN inter-exchange signalling

Conclusion

SIST EN 301 258 V1.2.1:2005 ensures organizations benefit from standardized, interoperable, and reliable recall functionalities in Private Integrated Services Networks. Its alignment with international and European norms makes it a trusted, future-proof choice for enterprises seeking efficient internal communications and simplified multi-vendor integration. For telecom professionals and network designers, referencing this standard is crucial for deploying advanced, standards-compliant enterprise telephony services.
