Overview

SIST EN 300 356-19 V3.1.3:2003 defines the stage three specifications for the Three-Party (3PTY) supplementary service within the Integrated Services Digital Network (ISDN) using Signalling System No.7 (SS7) and the ISDN User Part (ISUP) version 3 for international interfaces. This European standard, established by the Slovenski inštitut za standardizacijo (SIST) and based on the modified ITU-T Recommendation Q.734, provides the necessary signalling system protocols and switching functions to enable three-party calling services across pan-European ISDN implementations.

This document supplements the basic ISUP procedures by specifying additional generic protocol procedures required exclusively for the 3PTY service. While its main application is for international interconnections, it includes informative details for national network use to promote consistency.

Key Topics

• Three-Party (3PTY) Supplementary Service: Provides procedures for establishing, managing, and releasing three-party calls, allowing a user to connect with two other parties simultaneously.
• ISDN User Part (ISUP) Version 3: Specifies the signaling protocols that control call set-up, management, and release within ISDN networks across international boundaries.
• International Interface: Targets interoperability for international gateways between public telecommunications operators within Europe, ensuring seamless three-party call features.
• Stage Three Perspective: Focuses on protocol procedures and switching functions, building on the service description and functional requirements documented in related standards.
• Compatibility and Message Coding: Addresses compatibility parameter coding recommendations for seamless notification and service interaction between exchanges.
• Applicability: Intended for telecommunication services that carry speech, with coverage for both originating and terminating local exchanges.

Applications

The SIST EN 300 356-19 V3.1.3:2003 standard offers practical value in several key scenarios:

• International Business Communications: Enables reliable three-way calling features for organizations operating across borders, supporting business conferencing and group call requirements over ISDN.
• Carrier Interconnections: Provides a harmonized protocol for interoperability between national and international ISDN networks, ensuring consistent service availability for three-party calls.
• Public Switching Networks: Assists network operators in implementing supplementary services that enhance customer experience and differentiate service offerings.
• Integrated Service Providers: Supports the deployment of advanced voice services by aligning network components with internationally recognized procedures and signaling requirements.
• Telecommunication Equipment Manufacturers: Ensures that switching equipment and SS7 signaling stacks are compatible with pan-European ISDN three-party service expectations.

Related Standards

The Three-Party supplementary service is part of a broader suite of ISUP version 3 specifications. Key related standards include:

• EN 300 356-1: ISDN basic services and related signaling protocols
• EN 300 356-2: ISDN supplementary services procedures
• ETS 300 186: Three-Party supplementary service - Service Description
• ETS 300 187: Three-Party supplementary service - Functional capabilities and information flows
• ETS 300 188-1: DSS1 protocol specification for Three-Party service
• EN 300 403-1: DSS1 protocol for basic call control
• ITU-T Recommendation Q.734: Reference specification for Three-Party supplementary service (with modifications)
• CCITT Recommendation I.130: Characterization of telecommunication services and ISDN capabilities

By adhering to SIST EN 300 356-19 V3.1.3:2003, network operators, service providers, and equipment manufacturers ensure compatibility, reliability, and quality for three-party calling services over ISDN and SS7 networks in line with European and international requirements.
