Overview
SIST ETS 300 009 E1:2003 specifies the requirements for the Signalling Connection Control Part (SCCP) connectionless service within Signalling System No. 7 (SS7), supporting international interconnection in Integrated Services Digital Network (ISDN). Developed by SIST, this standard aligns with the corresponding ETSI and CCITT recommendations, focusing on connectionless relay and gateway functions between national and international networks. By defining methods for routing, addressing, and management in a global telecommunications environment, it enables reliable communication and interoperability across international ISDN infrastructures.
Key keywords: ISDN, SS7, SCCP, international interconnection, connectionless service, signalling, telecommunications standard.
Key Topics
Routing with Global Titles:
International SCCP messages require global titles (GT) for routing. Routeing based on Destination Point Code (DPC) or DPC plus SubSystem Number (SSN) is not permitted in international scenarios; the routing indicator must always specify routing on the global title.Address Information:
Addresses in international SCCP must include GT and SSN, ensuring accurate message delivery across borders. The inclusion of SSN is mandatory, promoting consistent address structuring for international communication.SCCP Management Procedures:
Restricted to updating translation tables for backup node rerouting upon network failures. Full management messaging or reacted status indications are not required for the international context, simplifying operations.Protocol Classes:
The standard applies only to SCCP connectionless services (protocol classes 0 and 1). Protocol classes 2 and 3, which introduce connection-oriented features, are not included.Load Sharing:
For protocol class 0, SCCP manages load sharing using Signalling Link Selection (SLS) codes. For class 1, in-sequence delivery is maintained according to sequence control, with fixed mapping of SLS codes at relay nodes.SSN Allocation for Mobile Services:
The standard introduces guidelines for SubSystem Number (SSN) allocation to support important mobile network functions, including HLR, VLR, MSC, EIR, and authentication centers, paving the way for extending SCCP’s applicability to mobile communications.
Applications
SIST ETS 300 009 E1:2003 is essential for:
- Telecommunications operators designing and maintaining ISDN networks with international interconnection requirements.
- Network equipment manufacturers implementing SS7 signalling features to ensure global interoperability of their devices.
- Regulatory authorities and standards organizations aiming to harmonize national and international digital network signalling.
- Mobile network operators leveraging the defined SSN allocation for critical functions like Home Location Register (HLR) and Mobile Switching Centre (MSC), supporting international roaming.
- Protocol developers and maintenance engineers ensuring adherence to address formatting, routing, and management processes outlined in the SCCP standard for efficient cross-border communication.
Related Standards
For comprehensive deployment and compliance, reference the following connected standards:
- CCITT Recommendations Q.711 - Q.714: Fundamental documents on SCCP functions, message definitions, formats, and procedures in SS7.
- CCITT Recommendation Q.716: Specifies SCCP performance requirements.
- ETSI ETS 300 008: Outlines the Message Transfer Part (MTP) for international ISDN interconnections, which underpins SCCP operations.
- ISDN and SS7 suite: Refer to additional standards addressing other SS7 components and ISDN services to ensure end-to-end compatibility.
Adhering to SIST ETS 300 009 E1:2003 ensures robust, internationally compatible signalling services for ISDN, addressing the growing need for reliable global telecommunications infrastructure.

Foreword
This European Telecommunication Standard (ETS) has been produced by the Signalling Protocols and
Switching (SPS) Technical Committee of the European Telecommunications Standards Institute (ETSI),
as working document T/S 43-03, and was adopted having passed through the ETSI standards approval
procedure.
This ETS is based on CCITT Recommendations Q.711 [1] to Q.714 [4] as recommended in the CCITT
Blue Book, 1988. The requirements of these CCITT Recommendations apply unless modified by the
exception statements contained in Clause 4 of this ETS. In addition, the standard includes the specific
requirements contained in Clause 5 of this ETS.
CCITT Recommendation Q.716 [5] shall also apply.
This ETS is also based on the following assumptions concerning the interconnection of national Signalling
Connection Control Parts (SCCPs):
- the Message Transfer Part (MTP) specified in ETS 300 008 [6] supports the SCCP for international
interconnection;
- at present, no SCCP users (subsystem) have been identified in the international network and,
therefore, no need exists for management messages to be originated or terminated. However,
Unitdata messages containing management information should be carried in the international
network as all other Unitdata messages.
- a global title including the country code, is required for routing in the international network. The
global title format of CCITT Recommendation Q.713 [3], § 3.4.2.3.4, is to be used (Global Title
Indicator = 0100).
