Overview
SIST EN 300 356-14 V3.1.3:2003 defines the stage three protocols and switching functions for the Explicit Call Transfer (ECT) supplementary service in the Integrated Services Digital Network (ISDN) environment. Focused on the international interface utilizing Signalling System No.7 (SS7) and the ISDN User Part (ISUP) version 3, this standard aligns with ITU-T Recommendation Q.732, clause 7 (1996) with certain modifications. The ECT supplementary service allows users to connect two existing calls, enabling direct communication between the other parties involved. This capability is essential for modern telecommunications networks supporting circuit-switched services in a pan-European and international setting.
Key Topics
- Explicit Call Transfer (ECT): ECT empowers a user, engaged in two separate calls, to merge them so that the two other parties can converse directly. This is a valuable supplementary service for business and customer service environments.
- ISDN and SS7 ISUP: The standard specifies the use of ISDN architecture and Signalling System No.7 with ISUP version 3 to implement and manage ECT services. These foundational technologies ensure interoperability and reliability in international telecom networks.
- Protocol Procedures: Detailed procedures and compatibility recommendations for parameters and messages relevant to ECT in SS7 networks are provided, emphasizing correct handling at international gateways and local exchanges.
- International and National Integration: While targeting international interconnections, the standard includes informative notes on incorporating national signaling specifics to facilitate seamless transfer across diverse networks.
Applications
SIST EN 300 356-14 V3.1.3:2003 is critical for:
- Public Network Operators: Ensuring robust support for explicit call transfer across international connections, enhancing service portfolios for subscribers.
- Telecommunications Equipment Manufacturers: Developing switches, gateways, and other ISDN/SS7-compliant devices capable of managing ECT procedures per the European and international interface requirements.
- Service Providers: Enabling advanced call control features, such as transferring calls between users without disconnecting, which are vital in contact centers, enterprise environments, and scenarios involving multi-party communications.
- Network Integrators: Facilitating interworking between different operators’ networks by standardizing procedures and protocol implementations for supplementary services like ECT.
