Overview
SIST EN 301 765 V1.1.1:2005 outlines the functional requirements for static circuit-mode inter-PINX connections within Private Integrated Services Networks (PISN). Based on the modified ISO/IEC 14474 standard, this document establishes the necessary mapping functions in exchanges of PISNs to support intervening network scenarios. These scenarios leverage circuit-mode bearer capabilities to connect Private Integrated Network Exchanges (PINX) through dedicated inter-PINX connections (IPCs). This standard aids organizations in ensuring interoperability, reliability, and consistent performance in private telephony networks.
Key Topics
- Private Integrated Services Network (PISN): Specifications for the architecture and underlying principles of private telephone networks using ISDN concepts.
- Inter-PINX Connections (IPCs): Requirements for static, dedicated connections between PINXs, supporting circuit-mode bearer services.
- Mapping Functions: Definition of the necessary mappings at exchanges to support static circuit-mode connections in PISN environments.
- Intervening Network Scenarios: Clarifies scenarios where connection between PINX is mediated by dedicated or cross-connect transmission systems.
- Reference Modifications: Adopts and modifies provisions of ISO/IEC 14474, replacing certain references and aligning terminology with EN standards.
Applications
Implementing SIST EN 301 765 V1.1.1:2005 is crucial for organizations that operate or develop private telecommunication systems requiring seamless connectivity between geographically dispersed branches or offices. Practical applications include:
- Enterprise Telephony Networks: Deployment and maintenance of corporate telephone systems with multiple sites, ensuring transparent static circuit-mode connections among branches.
- Network Equipment Manufacturers: Design and production of PISN-compliant hardware and software, guaranteeing interoperability and adherence to European and international standards.
- Systems Integration: Projects where multiple independent network segments (PINXs) need to interconnect reliably through static circuit-mode links.
- Telecommunications Service Providers: Offering services or managed solutions based on private ISDN technologies with guaranteed service quality across static connections.
- Migration and Upgrades: Facilitating the transition from legacy private networks to standards-based systems, supporting future-proof interconnectivity and potential integration with public ISDN environments.
