SIST ETS 300 133-7/A1 E1:2003

SIST ETS 300 133-7/A1 E1:2003 is the Slovenian adoption of ETS 300 133-7/A1 Edition 1, an ETSI amendment to Part 7 of the ERMES paging standard. It updates the operations and maintenance aspects of Paging Systems (PS) by revising ASN.1 object identifier assignments in Clause A.2 for ERMES-related definitions.

What does SIST ETS 300 133-7/A1 E1:2003 specify?

SIST ETS 300 133-7/A1 E1:2003 specifies amendments to ETS 300 133-7 (1992), Part 7: Operations and maintenance aspects. The amendment is focused on Clause A.2, where it corrects and renames object identifier assignments used in the standard’s ASN.1 material.

In practice, this document matters when an implementation, maintenance tool, or specification references ERMES object identifiers. It keeps the identifier structure aligned so different systems and documents use the same names and branches.

The document is organized as:

• a foreword identifying the amendment and its source,
• a set of amendment instructions for specific pages in Clause A.2,
• a history note.

What are the key requirements of SIST ETS 300 133-7/A1 E1:2003?

The amendment’s main technical effect is to update the object identifier naming in Clause A.2. For users of the standard, that means the ASN.1 definitions for services, protocols, and related object identifiers must follow the revised ERMES branches rather than the earlier naming.

Clause A.2 - paging domain and IOMC identifiers

Clause A.2 introduces a pagingDomain identifier branch and uses it for IOMC allocations. In practice, this tells implementers to place ERMES IOMC identifiers under the revised paging domain structure instead of the previous root.

Clause A.2 - IOMC-Service

Clause A.2 replaces the IOMC-Service reference with the ERMES-specific branch. This matters when systems identify service-related definitions, because the service name must point to the updated identifier tree.

Clause A.2 - IOMC-Protocol

Clause A.2 also updates IOMC-Protocol to the revised ERMES branch. For maintainers, this keeps protocol definitions and references consistent with the amended object identifier hierarchy.

Clause A.2 - IOMC-UsefulDefinitions

Clause A.2 revises the object identifier entry used for useful definitions. In practice, that means supporting documents and ASN.1 modules should reference the updated ERMES identifier when they point to shared definitions.

Clause A.2 - unchanged clause numbering

The amendment notes that the clause numbering has not changed. This helps readers apply the amendment to the original Part 7 document without renumbering the technical structure.

What terms does SIST ETS 300 133-7/A1 E1:2003 define?

• Paging Systems (PS) - the paging system family covered by the standard.
• Enhanced Radio MEssage System (ERMES) - the European radio message system addressed by Part 7.
• IOMC - the identifier family used in Clause A.2 for object identifier assignments.
• object identifier - an ASN.1 identifier used to name modules, services, and related definitions unambiguously.
• pagingDomainId - the revised identifier branch introduced for paging-domain allocations.
• ermesIomcId - the ERMES-specific identifier branch used in the amended object identifier paths.

Who uses SIST ETS 300 133-7/A1 E1:2003?

SIST ETS 300 133-7/A1 E1:2003 is used by telecommunications engineers, paging-system vendors, and standards specialists who maintain ERMES specifications. It is also relevant to interoperability teams and documentation owners who manage ASN.1 module names and object identifier trees.

Quality and conformity teams may use it when checking that products, software, or technical documentation reference the correct ERMES identifiers. Network and system maintainers use it to keep implementations aligned with the amended standard.

What changed in SIST ETS 300 133-7/A1 E1:2003 from the previous edition?

SIST ETS 300 133-7/A1 E1:2003 amends ETS 300 133-7 (1992) by changing selected lines in Clause A.2, especially the object identifier roots and names. The amendment updates the IOMC-related entries to use the ERMES pagingDomain and ermesIomcId branches, including IOMC-Service, IOMC-Protocol, and IOMC-UsefulDefinitions.

Which standards are used with SIST ETS 300 133-7/A1 E1:2003?

• ETS 300 133-7 (1992) - the base Part 7 document that this amendment modifies.

What does the SIST ETS 300 133-7/A1 E1:2003 document contain?

The document contains the foreword, the amendment instructions, and a history note. Its technical content is concentrated in Clause A.2 of the base standard, where specific object identifier lines are replaced.

It does not restate the full Part 7 text. Instead, it shows exactly where the ASN.1 naming is updated, which is useful when revising protocol definitions, maintenance documentation, or implementation references.
