Overview
SIST EN 301 254 V1.2.1:2005 is a Slovenian national standard adopted from the European standard EN 301 254, which endorses and modifies ISO/IEC 15049 (1997). This standard specifies the functional model, information flows, and service specifications for Advice of Charge (AOC) supplementary services within a Private Integrated Services Network (PISN). PISNs are commonly used in organizational environments to provide integrated voice, data, and supplementary telecommunication services based on ISDN concepts.
The standard establishes definitions, capabilities, and the facilitation of AOC services, assisting organizations in transparent call cost management. This helps ensure that users and network administrators can access reliable charge information during and after calls made through the private network.
Key Topics
- Advice of Charge (AOC) Services: Clarifies the requirements and models for providing call charge information to users, including real-time and end-of-call updates.
- Functional Model and Information Flows: Details the operational aspects and information exchanges necessary to deliver AOC supplementary services in a PISN environment.
- Integration with ISDN and OSI Frameworks: Aligns with ISDN-based telecommunications concepts and follows the OSI model for open systems interconnection.
- Normative References: Relates AOC functions to other fundamental PISN standards by referencing established ETSI and ISO/IEC documents (e.g., bearer services, call transfer, diversion services).
- Modification of ISO/IEC 15049: The Slovenian and European adoption includes specific localized adaptations, ensuring compatibility with regional telecommunication infrastructure while maintaining international conformity.
Applications
The implementation of SIST EN 301 254 V1.2.1:2005 yields significant practical benefits in various organizational contexts:
- Corporate Telephony Environments: Enables businesses to manage internal telephony costs by providing detailed call charge information to users and administrators.
- Cost Control and Accounting: Supports automated billing and internal cost allocation, facilitating transparency for calls made within, to, and from the PISN.
- VPN and Multi-Site Organizations: Useful for organizations operating Virtual Private Networks (VPNs) over PISN, as it standardizes the presentation and handling of charge-related information across diverse locations.
- Service Providers: Assists telecommunication service providers in offering standardized AOC supplementary services to enterprise customers, fostering trust and compliance.
- Interoperability: Ensures seamless operation and integration of AOC features across various PISN components and systems conforming to EN and ISO standards.
