3 Terms, definitions and abbreviations
3.1 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 50173-1 and EN 50174-1 and the following apply.
3.1.1
computer room space
area within the data centre that accommodates the data processing, data storage and telecommunication equipment that provides the primary function of the data centre.
3.1.2
data centre
structure, or group of structures, dedicated to the centralized accommodation, interconnection and operation of information technology and network telecommunications equipment providing data storage, processing and transport services together with all the facilities and infrastructures for power distribution and environmental control together with the necessary levels of resilience and security required to provide the desired service availability
Note Ito entry: A structure can consist of multiple buildings andlor spaces with specific functions to support the pnmary (unction.
Note 2 to entry: The boundaries of the structure or space considered the data centre wbich includes the infomiation and communication technology equipment and supporting environmental controls can be defined within a larger structure or building.

3.1.3
equipment outlet
fixed connecting device where the zone distribution cabling terminates and providing the interface to the equipment cabling
3.1.4
Intermediate distribution cable
cable connecting the intermediate distributor to the zone distributor
3.1.5
Intermediate distributor
distributor used to make connections between the main distribution cabling subsystem, intermediate distribution cabling subsystem, network access cabling subsystem and active equipment
3.1.6
local distribution point
connection point in the zone distribution cabling subsystem between a zone distributor and one or more equipment outlets
3.1.7
local distribution point cable LDP cable
cab’e connecting a local distribution point to an equipment outlet
4.4.1.2 Intermediate distribution cabling subsystem
The intermediate distribution cabling subsystem extends from an ID to the ZDs connected to it. The subsystem includes:
a) the intermediate distribution cables;
b) the mechanical termination of the intermediate distribution cables at the ID together with associated patch cords and/or jumpers at the ID:
c) the mechanical termination of the intermediate cables at the ZD.
Although equipment cords are used to connect the transmission equipment to the cabling subsystem, they are not considered part of the intermediate distribution cabling subsystem because they can be application- specific.
4.4.1.3 Main distribution cabling subsystem
The main distribution cabling subsystem extends from an MD to the IDs connected to it. The subsystem includes:
a) the main distribution cables;
b) the mechanical termination of the main distribution cables at the MD together with associated patch cords and/or jumpers at the MD:
c) the mechanical termination of the main distribution cables at the ID.
Although equipment cords are used to connect the transmission equipment to the cabling subsystem, they are not considered part of the main distribution cabling subsystem because they can beapplication-specific.
4.4.1.4 Network access cablIng subsystem
The network access cabling subsystem extends from an MD, ID or ZD to the ENIs and/or other distributors of the EN 50173 series connected to it. The subsystem includes:
a) the network access cables;
b) the mechanical termination of the network access cables at the ENI;
c) the mechanical termination of the network access cables at the MD, ID, ZO or other distributors of the EN 50173 series.
Although equipment cords are used to connect the transmission equipment to the cabling subsystem, they are not considered part of the network access cabling subsystem because they can be application-specific.BS/EN 50173-5-2018 pdf download.
