Overview

SIST EN 300 171 V1.2.1:2005 is a European standard that provides specifications, functional models, and information flows for the control aspects of circuit-mode basic services within Private Integrated Services Networks (PISN). Developed by the Slovenski inštitut za standardizacijo (SIST) and harmonized with ISO/IEC 11574 (1994) with amendments, this standard supports the standardized implementation of telecommunication services in private networks. It establishes the necessary guidelines for describing, managing, and supporting basic bearer and teleservices such as telephony, telefax, and videotex within PISN environments.

Key Topics

• Service Specification: Defines standardized descriptions for circuit-mode basic services such as telephony, telefax group 4, and syntax-based videotex.
• Control Aspects: Details the necessary control mechanisms required to support bearer services, including call establishment, information flow, and compatibility.
• Functional Models: Provides models representing the interaction between network components, supporting seamless service integration.
• Information Flows: Specifies how information is exchanged between PISN users and network entities, ensuring interoperability and service reliability.
• Modifications and Corrections: Incorporates updates and technical corrections to ensure clarity and alignment with related international standards.
• Teleservice Support: Addresses optional support for multiple teleservices with requirements for compatibility and communication attributes.
• Integration with ISDN/OSI Frameworks: Aligns PISN service concepts with Integrated Services Digital Network (ISDN) and Open Systems Interconnection (OSI) standards.

Applications

Implementing SIST EN 300 171 is crucial for organizations seeking to deploy reliable, feature-rich private telecommunication networks. Its applications include:

• Private Corporate Networks: Streamlining voice and data services over internal PISNs, facilitating seamless business communications.
• Virtual Private Networks (VPNs): Enhancing the management of circuit-mode services within enterprise VPN settings.
• Telephony and Fax Solutions: Ensuring standardized, high-quality support for telephone calls and group 4 telefax transmissions in private environments.
• Interoperability: Supporting integration and compatibility across vendors and systems by adhering to agreed protocols and information flows.
• Service Provider Networks: Helping telecommunication service providers build compliant, modular solutions for their private network clients.

Related Standards

SIST EN 300 171 is closely linked with several other key standards in private and integrated service networks:

• ISO/IEC 11574 (1994): International reference for PISN circuit-mode basic services, forming the base document for SIST EN 300 171.
• ETS 300 189: Defines addressing schemes for Private Telecommunication Networks.
• ETS 300 387: Provides methods for specifying basic and supplementary services in private networks.
• ETS 300 475-1: Outlines the reference configuration for PISN exchanges.
• ETS 300 111 / ETS 300 120 / ETS 300 262: Offer detailed service descriptions and requirements for specific teleservices such as 3.1 kHz telephony, group 4 telefax, and videotex.
• ETR 018 / ETR 076: Give additional guidance on ISDN service compatibility and standards application.

GeneralA PISN can support teleservices requiring the same bearer capabilities as the bearer services specified in the presentdocument. These teleservices include, for example:-
Telephony 3,1 kHz teleservice;-
Telefax group 4 teleservice; and-
Circuit-mode syntax-based videotex teleservice.The support by a PISN of one or more of these teleservices is optional. However, if a PISN supports one or more ofthese teleservices then it shall comply with this annex.The bearer capabilities and other special requirements used to support these teleservices are specified below. Otherwise,the impact of these teleservices on the network is the same as for the corresponding bearer service.The PISN shall convey an indication of the teleservice being used as High Layer Compatibility (HLC) information, fromthe calling PISN user to the called PISN user. Any use of this indication by the PISN is outside the scope of the presentdocument.A PISN may reject a request for a teleservice if the requested bearer capabilities are not those specified in this annex.NOTE 1:
