ISO/IEC 10742:1994/Amd 1:1995/Cor 1:1999

Overview

ISO/IEC 10742:1994/Amd 1:1995/Cor 1:1999 is an amendment and technical corrigendum to the international standard that defines elements of management information related to OSI Data Link Layer standards. Amendment 1 explicitly adds DCE conditions and new attributes to the management information model for the Data Link Layer. Technical Corrigendum 1 provides editorial corrections (for example renaming an annex and renumbering clauses) to ensure the document’s internal consistency. The document was prepared by ISO/IEC JTC 1/SC 6 and published in 1999.

Key topics and requirements

• Management information for the OSI Data Link Layer: The standard concerns the definition of management elements related to protocols at the Data Link Layer - i.e., the information needed to monitor, configure and manage data-link connections.
• Addition of DCE conditions: Amendment 1 introduces management conditions related to DCE (Data Circuit-terminating Equipment), clarifying how such conditions should be represented in the management model.
• New attributes: The amendment adds new attributes to the set of management information elements, extending the metadata available for Data Link Layer management.
• Editorial corrections: Technical Corrigendum 1 makes editorial adjustments (for example, changing “annex E” to “annex J” and renumbering clauses), improving accuracy and reference integrity.
• Standards governance: Prepared by ISO/IEC JTC 1, Subcommittee SC 6 (Telecommunications and information exchange between systems), reinforcing its role in interoperable telecommunications management.

Applications

• Network equipment vendors and firmware developers can use the standard to align management interfaces with OSI Data Link Layer expectations.
• Telecom operators and service providers benefit when devices expose consistent management attributes for monitoring and fault diagnosis at the Data Link Layer.
• Network management system (NMS) implementers can map these management elements into monitoring dashboards, alarms, and automated management processes.
• Test labs and conformance bodies use the amendment and corrigendum to verify that devices correctly implement the extended attributes and DCE condition reporting.

Who should use this standard

• Network engineers and architects working with OSI-based or legacy telecommunications systems
• Device manufacturers (DTE/DCE interface implementers)
• Software developers of network management tools
• Standards bodies and interoperability test teams

Related standards

• ISO/IEC 10742 (base standard) and other OSI Data Link Layer specifications
• ISO/IEC JTC 1/SC 6 publications on telecommunications and information exchange
