Overview
SIST EN 300 356-7 V4.1.2:2004 is a Slovenian standard harmonized with the European standard EN 300 356-7, as developed by ETSI. It focuses on the implementation of the Integrated Services Digital Network (ISDN) Signalling System No. 7 (SS7), specifically the ISDN User Part (ISUP) version 4 for the international interface. Part 7 of the series details the Terminal Portability (TP) supplementary service, based on modified provisions of ITU-T Recommendation Q.733, clause 4 (1993).
The standard establishes the signaling protocols and switching functions necessary to support terminal portability across pan-European ISDN networks. Its scope is limited to protocol procedures for international ISDN interconnection, providing the foundation for seamless terminal mobility within the active state of a call.
Key Topics
- ISDN User Part (ISUP) version 4: Defines the set of signaling procedures for managing call set-up, control, and release across international ISDN gateways.
- Terminal Portability (TP): Enables users to move an active call between terminals (or sockets) on the same basic access line without call interruption, supporting telecommunication services that require live human attendance, such as voice and video calls.
- Signalling System No.7 (SS7): The protocol suite facilitating robust and standardized signaling for advanced telecommunications networks.
- International Interface: Focuses on interoperability at the boundary between national networks, ensuring TP services operate smoothly between countries.
- Supplementary Service: TP is classified as an ISDN supplementary service, augmenting the base functionality of call handling and management.
Applications
The implementation of terminal portability as defined in SIST EN 300 356-7 V4.1.2:2004 offers several practical benefits:
- Business Communications: Enterprises with multiple terminals or desk locations can reassign calls during ongoing communication, improving workforce mobility and responsiveness.
- National and International Telecom Operators: Supports operators in delivering enhanced user experiences through advanced ISDN features, ensuring service consistency across borders.
- Network Equipment Manufacturers: Provides a uniform protocol reference for developing ISUP-compliant switches, gateways, and signaling platforms for global interoperability.
- Migration and Modernization: Facilitates integration with newer digital infrastructures and legacy ISDN environments, ensuring ongoing support for supplementary services like TP during phased network upgrades.
Use Cases:
- Moving an active phone call from a desk phone to a meeting room terminal within the same organization
- Seamless video telephony experiences in environments with shared access terminals
- Ensuring active sessions are maintained during transitions between network segments or locations
