SIST EN 300 119-1 V2.1.1:2006

• Abstract:

  The present document sets out the major engineering requirements for telecommunications equipment forming part of a public telecommunications network installed either on public telecommunications operators' sites or in premises of operators' customers. It is expected that the areas of transmission equipment and switching equipment will increasingly merge into one. As a result, the present document should be applied to all forms of telecommunications equipment. The operating authorities should be given the data to help them plan buildings and building utilization, including ceiling heights, equipment and traffic areas, hallways and doors and transport installations (freight elevators, loading ramps, etc.). They also need to be able to compute the structural design requirements and the type and scope of air conditioning needed. It should be made possible to expand existing installations and to combine equipment from different manufacturers. Therefore, operating authorities are guaranteed a wide scope for system selection. The equipment designer should be able to derive a suitable mechanical design for telecommunications equipment. Such a scope calls for standardization of certain levels in the mechanical hierarchy, e.g.:; • dimensions for racks, miscellaneous racks and subracks. The definitions of cabinets and racks contained in IEC publication 60917-1 [1] are:; - Cabinet: a free-standing and self-supporting enclosure for housing electrical and/or electronic equipment. It is usually fitted with doors and/or side panels which may or may not be removable;; - Rack: a free-standing or fixed structure for housing electrical and/or electronic equipment.; • accessibility of rack rows;; • cable access;; • heat load;; • static load;; • compatibility with Electro-Magnetic Compatibility (EMC) and Electro-Static Discharge (ESD) requirements.; Existing equipment practices are not covered by the present document.

Overview

SIST EN 300 119-1 V2.1.1:2006 is a European standard published by the Slovenian Institute for Standardization (SIST) and aligned with the ETSI EN 300 119-1 standard from the European Telecommunications Standards Institute. This part provides an introduction and establishes the terminology for equipment practice within the field of environmental engineering for telecommunications networks.

The standard outlines the main engineering requirements for telecommunications equipment that forms part of public networks. It covers the installation and integration of such equipment both at telecommunications operators’ sites and on customer premises. As network technologies converge and integration between transmission and switching equipment increases, this standard aims to provide a unified approach applicable to a broad range of equipment types.

Key Topics

SIST EN 300 119-1 V2.1.1:2006 addresses foundational topics in telecommunications equipment engineering, including:

• Terminology and Definitions: Introduces clear, standardized language for describing racks, cabinets, subracks, and other infrastructure elements used in telecommunications.
• Mechanical Hierarchy Standardization: Defines key aspects for compatibility and modularity such as:
  • Standardized dimensions of racks, miscellaneous racks, and subracks
  • Definitions for cabinets (self-supporting enclosures with or without removable panels) and racks (fixed or free-standing structures)
• Interface and Compatibility: Ensures mechanical interfaces between equipment elements from different manufacturers work seamlessly, promoting interoperability.
• Site Planning Guidance: Provides essential data for operators to plan building layouts, including:
  • Equipment and traffic areas
  • Hallway widths and door placements
  • Transport installations like freight elevators and loading ramps
  • Calculation of structural design parameters and air conditioning requirements
• Expansion and Flexibility: Supports the expansion of existing systems and the integration of equipment from multiple suppliers, enabling broad system selection.
• Environmental Requirements: Addresses structural and environmental considerations such as:
  • Accessibility, cable access, heat load, and static load
  • Electro-Magnetic Compatibility (EMC) and Electro-Static Discharge (ESD) compatibility

Applications

SIST EN 300 119-1 is essential for:

• Telecommunications Operators: Supports effective planning and site use, ensuring installations accommodate future growth and allow for diverse equipment choice.
• Equipment Manufacturers and Designers: Provides clear criteria for designing mechanically compatible and expandable products, reducing the risk of incompatibility across vendors.
• Building Planners and Integrators: Delivers the core requirements for infrastructure planning, helping compute load-bearing capacities, air conditioning needs, transport pathways, and layout optimization.
• Project Managers and Installers: Facilitates straightforward expansion and upgrades of telecommunications facilities by ensuring standardization at all key mechanical interfaces.

Related Standards

SIST EN 300 119-1 serves as an introductory part of a wider family of European standards focusing on mechanical and environmental aspects of telecommunications equipment:

• SIST EN 300 119-2: Engineering requirements for racks and cabinets
• SIST EN 300 119-3: Engineering requirements for miscellaneous racks and cabinets
• SIST EN 300 119-4: Engineering requirements for subracks in miscellaneous racks and cabinets
• SIST EN 300 119-5: Thermal management for racks, cabinets, and subracks

Additionally, the standard references IEC 60917-1 for mechanical structures and definitions in electronic equipment.
