Overview

SIST EN 300 356-6 V3.1.3:2003 is the Slovenian adoption of the European standard that outlines the stage three (protocol procedures and switching functions) for the Connected Line Identification Restriction (COLR) supplementary service within the Integrated Services Digital Network (ISDN) environment. This standard applies the protocols set out in Signalling System No.7 (SS7), ISDN User Part (ISUP) version 3, specifically for international interfaces, and is based on ITU-T Recommendation Q.731, clause 6 (1993) with agreed modifications.

The purpose of this document is to provide the technical details required for network operators and equipment manufacturers to support the COLR supplementary service, enabling the connected party to prevent their ISDN number from being displayed to the calling party during a call setup. This feature is valuable for both privacy and security in various telecommunications scenarios.

Key Topics

• ISDN User Part (ISUP) Version 3
  Defines protocols and functional capabilities required for ISDN in international connections using the Signalling System No.7 protocol stack.

• Supplementary Services
  Focuses on the COLR supplementary service, which grants the connected party control over the presentation of their identifier.

• Protocol Procedures and Switching Functions
  Outlines stage three (per CCITT Rec. I.130) - the detailed signaling system protocols, formats, codes, and procedures required to implement COLR internationally.

• International Interface Focus
  Specifies how the service operates over international gateways, including optional provisions for national usage based on operator implementation.

• Service Applicability and Limitations
  COLR is intended for all telecommunication services using ISDN and is applicable specifically to international ISUP interfaces, with national signaling differences considered as informative guidance.

Applications

The standard provides practical value to a range of ISDN-based services and network deployments:

• Telecom Operator Implementations
  Ensures that ISDN services comply with European and global privacy requirements by preventing unauthorized disclosure of the connected line’s identification.

• Equipment Manufacturers
  Offers a clear protocol specification for developing compatible hardware and software for switches, gateways, and SS7-ISUP signaling elements.

• Enterprise and Public Sector Networks
  Supports security and privacy for organizations where the confidentiality of endpoint identifiers is crucial.

• Cross-border and International Communications
  Facilitates seamless interconnection between national and international ISDN networks by specifying how COLR should be handled at gateway exchanges.

Related Standards

For effective implementation and integration, consider these related ISDN and signaling standards:

• EN 300 356-1: Basic services for ISUP version 3
• EN 300 356-2: ISDN supplementary services
• ETS 300 095: Service description for COLR
• ETS 300 096: Functional capabilities and information flows for COLR and COLP
• ETS 300 098-1: Protocol specification for COLR using DSS1
• EN 300 403-1: Signaling network layer for basic call control (DSS1 protocol)

By aligning with SIST EN 300 356-6 V3.1.3:2003 and its related documents, network operators and developers can ensure full interoperability and regulatory compliance for Connected Line Identification Restriction in international ISDN signaling environments.
