SIST-TP ETSI/ETR 090 E2:2005

SIST-TP ETSI/ETR 090 E2:2005 is the Slovenian publication of ETSI ETR 090, Second Edition, from the European Telecommunications Standards Institute (ETSI). It specifies the structure of the Intelligent Network (IN) domain in the ETSI common domain object identifier tree, including the CTM branch and the ASN.1 names used to identify the IN subdomains. In practice, it is used when allocating object identifiers and when preparing the CTM stage 3 description.

What does SIST-TP ETSI/ETR 090 E2:2005 specify?

SIST-TP ETSI/ETR 090 E2:2005 describes how the IN domain is arranged inside the ETSI object identifier tree defined by ETS 300 351. The report is informative and focuses on the object identifier structure needed for the common domain, with CTM called out in the scope.

The document is organized as:

• Foreword
• 1 Scope
• 2 References
• 3 Definitions
• 4 Abbreviations
• 5 Structure of the IN domain
  • 5.1 Tree structure
  • 5.2 ASN.1 description
• History

What are the key requirements of SIST-TP ETSI/ETR 090 E2:2005?

SIST-TP ETSI/ETR 090 E2:2005 is mainly a structural and registration document rather than a conformance standard. Its key value is that it defines the IN domain branch, its named subdomains, and the ASN.1 identifiers used to represent them.

Scope and registration context

Clause 1 says the report describes the structure for the IN domain of the common domain of the ETSI object identifier tree. That matters because it tells identifier managers where this branch belongs in the wider ETSI naming system. Clause 2 ties the report to ETS 300 351 for rules and registration procedures, which is the framework used when assigning these identifiers.

Common domain meaning

Clause 3 defines common domain as a set of objects that are part of the definition of a protocol or a set of related protocols. In practice, this means the object identifier tree groups protocol-related objects rather than hardware products or network sites.

Tree structure for the IN domain

Clause 5.1 presents the proposed IN domain tree. It shows branches for IN Network, UPT, and CTM, and it notes that the deeper structure under IN Network is only an example. For a reader, that means the report gives the top-level allocation for the IN area, but not every lower-level branch in the same way.

ASN.1 identifiers

Clause 5.2 provides the ASN.1 definition for the IN domain. It defines the IN domain identifier itself, then the subdomain identifiers for in-Network, in-Upt, and in-Ctm. This is the part implementers use when they need a machine-readable identifier structure.

Common component naming

Clause 5.2 also defines CommonComponentId and uses it for moduleId and ac-Id. In practice, this gives a simple way to name common components inside the IN subdomains and keeps the naming scheme consistent.

CTM use case

The scope says the CTM object identifier is needed for the CTM stage 3 description produced by SPS2. That makes the report relevant to teams preparing CTM specifications and the related identifier allocation work.

What terms does SIST-TP ETSI/ETR 090 E2:2005 define?

• common domain - A set of objects that belong to a protocol definition or to a set of related protocols.
• ASN.1 - Abstract Syntax Notation One, the notation used here for the object identifier module.
• IN - Intelligent Network, the domain addressed by the report.
• CTM - Cordless Terminal Mobility, one of the IN subdomains named in the ASN.1 structure.
• UPT - Universal Personal Telecommunications, another named IN subdomain.
• AC - Application Context, a component named in the structure notes and abbreviations.
• moduleId - A common component identifier used for structuring IN subdomains.
• ac-Id - A common component identifier used for structuring IN subdomains.

Who uses SIST-TP ETSI/ETR 090 E2:2005?

SIST-TP ETSI/ETR 090 E2:2005 is used by ETSI technical committees, protocol designers, and registration or numbering specialists working on the ETSI object identifier tree. It is also relevant to teams involved with Intelligent Network, CTM, and UPT specifications, especially when they need a registered object identifier structure for stage 3 or protocol documentation.

What changed in SIST-TP ETSI/ETR 090 E2:2005 from the previous edition?

SIST-TP ETSI/ETR 090 E2:2005 is the second edition of ETSI ETR 090. The document history records a first edition from July 1993 and this second edition from November 1996.

Which standards are used with SIST-TP ETSI/ETR 090 E2:2005?

• ETS 300 351 - Provides the ETSI object identifier tree rules and registration procedures that the report relies on.
• ETS 300 374-1 - Provides the Intelligent Network Capability Set 1 (CS1) Core Intelligent Network Application Protocol (INAP) specification and defines the modules and Application Context referenced in the tree structure notes.

What does the SIST-TP ETSI/ETR 090 E2:2005 document contain?

The document contains a foreword, a scope, references, definitions, abbreviations, a tree structure section, an ASN.1 description, and a history section. The tree structure section includes a figure showing the proposed IN domain placement in the ETSI object identifier tree. The ASN.1 section gives the formal identifier names for the IN domain and its subdomains, including in-Network, in-Upt, and in-Ctm. It also includes the CommonComponentId type and the identifiers used to structure IN subdomains.
