Overview
SIST EN 300 356-17 V3.1.3:2003 outlines the international protocol requirements for the implementation of the Call Waiting (CW) supplementary service within the Integrated Services Digital Network (ISDN) using Signalling System No.7 (SS7) and the ISDN User Part (ISUP) version 3 for the international interface. As part of the European telecommunications standards developed by the Slovenian Institute for Standardization (SIST) and based on modifications to ITU-T Recommendation Q.733, this document details the procedures and switching functions required to support Call Waiting at the international level.
This standard is particularly relevant to public telecommunications operators and network implementers who aim to provide seamless Call Waiting functionality across pan-European ISDN services.
Key Topics
- Call Waiting Supplementary Service: Provides specifications for alerting a subscriber of an additional incoming call when all interface information channels are in use, allowing the user choices such as accepting, rejecting, or ignoring the waiting call.
- Stage 3 Protocols: Focuses on protocol procedures and switching functions (stage 3), as per CCITT Recommendation I.130, necessary to facilitate the Call Waiting service over the ISDN international interface.
- International Interconnect: Applies specifically to the international ISDN interconnection, detailing required message formats, signal codes, and network actions at both originating and destination local exchanges.
- Compatibility: Includes guidelines on interoperability with networks not supporting Call Waiting, as well as informative annexes on coding compatibility for protocol parameters.
- Reference to Supplementary Services: Places Call Waiting within a comprehensive framework of ISUP-based supplementary services, facilitating consistent integration with features like call hold, call transfer, and three-party services.
Applications
The primary application of SIST EN 300 356-17 V3.1.3:2003 is in the deployment and management of ISDN services across international network interfaces, ensuring consistent Call Waiting functionality even when interacting with diverse national ISDN implementations. Practical use cases include:
- Telecommunication Operators: Implementing robust Call Waiting support as part of international ISDN offerings, enhancing customer experience and service reliability.
- ISDN Network Equipment Vendors: Developing and testing network components such as switches, gateways, and SS7-ISUP stacks that require compliance with international Call Waiting signaling procedures.
- Interoperability Testing: Supporting protocol conformance and interoperability tests with other ISDN supplementary services, ensuring feature parity across international connections.
- Carrier Networks: Managing service behavior between national and international gateways, particularly in scenarios where national networks may not support Call Waiting service natively.
Related Standards
SIST EN 300 356-17 V3.1.3:2003 should be considered within the context of the broader ISDN and SS7 ecosystem. Key related standards include:
- EN 300 356-1: ISDN Basic Services – foundational protocol requirements.
- EN 300 356-2: ISDN Supplementary Services – overview of additional services beyond basic call handling.
- ETS 300 056: Call Waiting Service Description – detailed user-level description.

- ITU-T Q.733: Original specification for Call Waiting in the ISUP (as modified).
- EN 300 356 Parts 3-19: Range of supplementary services including Call Hold, Call Transfer, Three-party, and Malicious Call Identification.
By adhering to this standard, ISDN operators and equipment suppliers ensure seamless integration and ongoing compatibility for Call Waiting services across European and international telecom networks. This results in enhanced service offerings, support for legacy infrastructure, and a consistent user experience in multi-operator environments.
