SIST EN 301 991 V1.1.1:2005 PDF

Overview

SIST EN 301 991 V1.1.1:2005 is a Slovenian standard that endorses the European Standard EN 301 991. It specifies the inter-exchange signalling protocol for Short Message Service (SMS) designed for Private Integrated Services Networks (PISN). This standard is based on ISO/IEC 21990 (2002) with modifications to align with European requirements.

PISN refers to private telecommunication networks that often utilize concepts from the Integrated Services Digital Network (ISDN), enabling organizations to manage internal and external communication efficiently. The protocol detailed in SIST EN 301 991 V1.1.1:2005 supports reliable SMS communication between exchanges within these private networks, using the QSIG protocol suite as a foundation.

Key Topics

• Private Integrated Services Network (PISN): Frameworks and protocols for operating private telephone and data networks, closely aligned with ISDN principles.
• Inter-exchange Signalling Protocol: Messaging and communication rules between network exchanges, ensuring interoperability and effective routing of SMS within PISNs.
• Short Message Service (SMS) Support: Mechanisms for transferring short text messages between users connected to different exchanges within the same PISN.
• QSIG Protocol Suite: A set of standardized protocols (including PSS1) that enables advanced supplementary services in PISNs.
• ISO/IEC and ETSI Alignment: Adoption and adaptation of key international and European standards to ensure compatibility and integration with broader telecommunication networks.

Applications

SIST EN 301 991 V1.1.1:2005 is applicable in several key scenarios:

• Enterprise Telecommunications: Facilitates SMS communication between different sites within a large organization's private network, such as branch offices or campuses.
• Unified Communications Solutions: Forms the basis for integrating SMS with other services (voice, data, supplementary services) in modern unified communication platforms.
• Enhanced Messaging Services: Enables reliable message delivery and advanced messaging features within closed, secure business environments.
• Interoperability: Provides guidelines and references for integrating private telephony infrastructure with public networks and equipment from multiple vendors.

The adoption of this standard ensures streamlined, secure, and consistent short message exchange within private networks. It supports organizational productivity by enabling message-based services, notifications, and alerts across distributed network environments.

Related Standards

SIST EN 301 991 V1.1.1:2005 references and aligns with several related standards to ensure comprehensive functionality and interoperability:

• EN 300 172: Protocols for basic circuit-mode services in PISN.
• ETS 300 475-1: Reference configurations for private telecommunication networks.
• EN 300 239: Protocols supporting generic supplementary services in PISN.
• ETS 300 238: Name identification supplementary services.
• EN 301 255: Protocols for message waiting indication in PISNs.
• EN 301 990: Specifications for SMS supplementary service within PISN.

Together, these standards form an integrated framework that supports a wide range of telecommunication and messaging capabilities in private digital networks.

By following SIST EN 301 991 V1.1.1:2005, organizations benefit from internationally recognized best practices for SMS communication within PISN environments. This not only ensures technical reliability and security but also promotes future-proof investments in network infrastructure.
