ISO/IEC 11458:1993

ISO/IEC 11458:1993 addresses VICbus inter-crate cable bus requirements for microprocessor systems, making it a relevant technical document for teams evaluating board-level and system-level interconnection architectures. Based on the title, it is concerned with the cable bus used between crates, where signal integrity, connector interfaces, and operational consistency can affect overall system performance. For engineering, procurement, and compliance workflows, ISO/IEC 11458:1993 supports technical review and documented evaluation of how distributed microprocessor equipment is interconnected.

What is ISO/IEC 11458:1993?

ISO/IEC 11458:1993 is the 1993 edition of the reference associated with VICbus inter-crate cable bus arrangements in information technology microprocessor systems. As a derived document connected to the parent reference ISO/IEC 11458, it should be viewed as supporting technical material within that framework rather than as a separate standalone design guide. It is useful when assessing how inter-crate cabling is defined, reviewed, or referenced during conformity assessment, technical validation, and engineering documentation control.

Applications of ISO/IEC 11458:1993

This reference is most relevant where microprocessor-based equipment is assembled across multiple crates or modules and an inter-crate cable bus must be documented, reviewed, or verified. It may support system integration work, laboratory evaluation, hardware procurement, and configuration control in environments that depend on consistent electrical interconnects. Teams involved in technical assessment, design verification, or compliance workflows can use it to understand the bus concept in relation to the parent document and to align internal documentation with the intended interface structure.

Why is ISO/IEC 11458:1993 important?

ISO/IEC 11458:1993 matters because bus interconnection details can influence interoperability, reliability, and the repeatability of verification activities in complex microprocessor systems. A clear reference helps reduce implementation ambiguity during engineering review, testing workflows, and procurement decisions, especially when multiple crates or subsystems must operate together. It also supports quality assurance and regulatory preparation by giving teams a stable compliance reference for documenting the intended cable-bus arrangement and assessing whether a system build aligns with the expected technical framework.

• Supports review of VICbus inter-crate cabling used in modular microprocessor systems
• Useful for configuration control, technical validation, and engineering documentation
• Helps align procurement and system integration decisions with the parent reference structure
• Can inform conformity assessment and laboratory evaluation of interconnect arrangements
