Overview
SIST EN 300 356-18 V3.1.3:2003 is a European standard focused on the Integrated Services Digital Network (ISDN), specifically addressing Signalling System No.7 (SS7) and the ISDN User Part (ISUP) version 3 for international interfaces. This part, Part 18, details the Completion of Calls to Busy Subscriber (CCBS) supplementary service in alignment with ITU-T Recommendation Q.733, clause 3 (1997), with specific modifications for European application. Developed by the Slovenian Institute for Standardization (SIST) and harmonized with the European Telecommunications Standards Institute (ETSI), this standard defines the additional network procedures needed to support the CCBS service beyond basic call capabilities.
Key Topics
- CCBS Supplementary Service: Provides the protocol and switching procedures that allow users whose call attempts encounter a busy line to be notified and automatically have their call completed once the destination becomes free, without re-dialing.
- ISUP Protocol Enhancement: Specifies additional ISUP version 3 procedures required for CCBS on international ISDN interfaces, building on core SS7 signalling principles.
- International ISDN Interconnection: Focuses on CCBS implementation for cross-border and pan-European telecommunication networks, ensuring interoperability between national ISDNs at the international interface.
- Alignment with ITU-T Standards: Adopts and modifies ITU-T Rec. Q.733, ensuring compatibility with international signalling standards while reflecting European operational requirements.
Applications
- Telecommunication Networks: Implements CCBS across public switched telephone networks (PSTN) based on ISDN, facilitating advanced call handling and improved user experience.
- Carrier Interconnection: Ensures unified handling of busy signals and call completion between different carriers across borders, vital for reliable international communication.
- Network Equipment Vendors: Serves as a reference for developers of switching and signalling equipment, ensuring products meet European interoperability standards.
- Service Providers: Supports operators in offering value-added supplementary services that increase call completion rates, enhancing customer satisfaction and retention.
Practical Benefits:
- Increased Call Completion Rate: Reduces lost call opportunities when a subscriber is busy by automating re-attempts.
- Enhanced User Satisfaction: End-users do not need to manually redial, streamlining their communication experience.
- Consistent International Service Delivery: Aligns national implementations with international requirements, reducing service barriers across European networks.
