SIST EN 300 119-1 V2.1.1:2006
(Main)Environmental Engineering (EE); European telecommunication standard for equipment practice; Part 1: Introduction and terminology
- 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.

SIST EN 300 119-1 V2.1.1:2006 is the Slovenian adoption of the ETSI European standard EN 300 119-1 Version 2.1.1. It is an Environmental Engineering (EE) standard for telecommunications equipment practice in public telecommunications networks, aimed at operators, equipment designers, and manufacturers who need a common basis for mechanical interfaces and terminology.
What does SIST EN 300 119-1 V2.1.1:2006 specify?
SIST EN 300 119-1 V2.1.1:2006 sets the framework for the EN 300 119 series. It defines the scope of the equipment practice, the mechanical interface concept, and the multi-level approach used across the family.
The standard applies to telecommunications equipment installed on public telecommunications operators' sites or in operators' customers' premises. It is intended for all forms of telecommunications equipment, because transmission and switching equipment are expected to merge in practice.
A key purpose is to give operating authorities the data they need for building planning and installation planning, including space, access, structural loading, and air conditioning. Existing equipment practices are excluded from its scope.
The document is organized into a foreword, clauses 1 to 4, references, and history. The wider series is split into these parts:
| Part | What it covers |
|---|---|
| Part 1 | Introduction and terminology |
| Part 2 | Engineering requirements for racks and cabinets |
| Part 3 | Engineering requirements for miscellaneous racks and cabinets |
| Part 4 | Engineering requirements for subracks in miscellaneous racks and cabinets |
| Part 5 | Thermal management |
What are the key requirements of SIST EN 300 119-1 V2.1.1:2006?
SIST EN 300 119-1 V2.1.1:2006 does not set detailed product dimensions itself. Instead, Clauses 3 and 4 define the interface rules and the level at which common mechanical requirements have to be stated.
Mechanical interfaces and co-ordination dimensions
Clause 3 says that an equipment practice shall specify the mechanical interfaces between parts. These interfaces are the physical boundaries between parts, and they are described by co-ordination dimensions. In practice, this is what lets designers make parts fit together consistently.
Clause 3 also says that environmental considerations, including EMC and ESD, shall be handled within those dimensional limits. That matters because electromagnetic and electrostatic issues must be considered alongside the mechanical layout, not after the enclosure has already been fixed.
The multi-level approach
Clause 4 explains that subracks are usually mounted in racks/cabinets, so interfaces exist at more than one level. To avoid unnecessary detail, the standard limits minimum requirements to interfaces between equipment from different manufacturers, or between functionally different equipment from one manufacturer.
Clause 4 also treats equipment delivered in a rack/cabinet from a single manufacturer as one independent mechanical entity. In practice, that means the common requirements focus on the rack/cabinet-to-environment interface rather than on every internal interface inside the enclosure.
For miscellaneous racks/cabinets, Clause 4 says the specification is driven by the interface to the environment and the interface between the rack and the installed subracks. This is important when a rack must accept subracks from several equipment types or suppliers.
Planning data and practical design points
The scope lists the types of data operating authorities need for planning buildings and building use: ceiling heights, equipment and traffic areas, hallways and doors, freight elevators, loading ramps, structural design needs, and air conditioning needs. That is the information used when deciding whether a room can house the equipment and how it should be serviced.
The scope also identifies the mechanical hierarchy items that need standardization: dimensions for racks, miscellaneous racks and subracks, accessibility of rack rows, cable access, heat load, static load, and EMC and ESD compatibility. These are the points that affect layout, maintenance access, loading, cooling, and interchangeability.
What terms does SIST EN 300 119-1 V2.1.1:2006 define?
SIST EN 300 119-1 V2.1.1:2006 uses a small set of core terms that support the rest of the series.
- Cabinet - A free-standing, self-supporting enclosure for electrical and/or electronic equipment, usually with doors and/or side panels.
- Rack - A free-standing or fixed structure for housing electrical and/or electronic equipment.
- Mechanical interfaces - The physical boundaries between different parts of the equipment concerned.
- Co-ordination dimensions - The dimensions used to define and match those interfaces.
- Miscellaneous rack/cabinet - A rack/cabinet intended to accommodate subracks of several different types of equipment and/or suppliers.
- EMC - Electro-Magnetic Compatibility.
- ESD - Electro-Static Discharge.
Who uses SIST EN 300 119-1 V2.1.1:2006?
SIST EN 300 119-1 V2.1.1:2006 is used by public telecommunications operators, equipment designers, and manufacturers of telecommunications equipment. It is also useful for building planners and facility teams who need to size rooms, access paths, support structures, and cooling for telecom installations.
For buyers and quality managers, it helps when comparing racks, cabinets, subracks, and mixed-supplier equipment on a common mechanical basis. For engineers, it gives the vocabulary and interface framework needed before applying the more detailed parts of the series.
What changed in SIST EN 300 119-1 V2.1.1:2006 from the previous edition?
The document history lists earlier editions as ETS 300 119-1 published in January 1994 and V2.1.0 in May 2004, followed by publication of V2.1.1 in September 2004. SIST EN 300 119-1 V2.1.1:2006 corresponds to EN 300 119-1 Version 2.1.1.
Which standards are used with SIST EN 300 119-1 V2.1.1:2006?
SIST EN 300 119-1 V2.1.1:2006 cites these companion documents:
- IEC 60917-1 - Provides the generic standard for modular mechanical structures and the cabinet and rack definitions used in the text.
- ETSI EN 300 119-2 - Covers engineering requirements for racks and cabinets.

- ETSI EN 300 119-4 - Covers engineering requirements for subracks in miscellaneous racks and cabinets.
- ETSI EN 300 119-5 - Covers thermal management solutions for indoor restricted-access installations.
What does the SIST EN 300 119-1 V2.1.1:2006 document contain?
The document contains a foreword that places Part 1 in the five-part EN 300 119 series and links it to the work of ETSI Technical Committee Environmental Engineering. Clause 2 lists the references, Clause 3 defines mechanical equipment interfaces, and Clause 4 explains the multi-level approach.
It also includes a figure that shows the relationship between racks/cabinets, miscellaneous racks/cabinets, and subracks. In practice, the document is used as the starting point for mechanical design, interface specification, and installation planning across the rest of the series.
