Introduction
The increasing interaction between the different elements of the Information Communication Technology (ICT) sector
(hardware, middleware, software and services) supports the concept of convergence in which:
• multi-service packages can be delivered over a common infrastructure;
• a variety of infrastructures is able to deliver these packages;
• a single multi-service-package may be delivered over different infrastructures.
As a result of this convergence, the development of new services, applications and content has resulted in:
• an increased demand for bandwidth, reliability, quality and performance, with a consequent increase in the
demand for power which has implications for cost and, in some cases, availability;
• an associated continuous evolution of ICT equipment.
It is therefore important to consider the environmental viability of all network elements necessary to deliver the required
services in terms of the management of their operational aspects i.e. energy management (including energy efficiency)
and the management of the End-of-Life (EoL) of the ICT equipment.
NOTE: The term "environmental viability" is used while recognizing that well established treatments of
"sustainability" feature three separate viability objectives (environmental, economic and social). For the
purposes of this multi-part deliverable, only operational aspects of environmental viability are considered.
A wider approach to environmental viability takes other factors into account including the use of raw
materials and avoidance of hazardous substances in the construction of infrastructure or ICT equipment-
these factors are not considered.
New technologies and infrastructure strategies are expected to enable operators to decrease the energy consumption, for
a given level of service, of their existing and future infrastructures thus decreasing their costs. This requires a common
understanding among market participants that only standards can produce.
This multi-part deliverable specifies the general engineering of various broadband infrastructures to enable the most
effective energy management (and management of other resources) and the appropriate measures for EoL treatment of
ICT equipment. Certain of the standards may specify requirements for interoperability.
The present document is part 1 of a multi-part deliverable and provides an overview of the standards series together
with a definition of the common and generic aspects to which the other standards in the series conform.
The present document been produced by ETSI Technical Committees Access, Terminals, Transmission and
Multiplexing (ATTM) and Cable in close collaboration with CENELEC via the Installations and Cabling Co-ordination
Group (ICCG).

1 Scope
The present document is part 1 of a multi-part deliverable which specifies the general engineering of various broadband
infrastructures to enable the most effective energy management (and management of other resources) and the
appropriate measures for End-of-Life (EoL) treatment of ICT equipment.
This multi-part deliverable does not address the following aspects of the broadband network sub-systems:
• implications for carbon "footprint";
• resources used to construct the sub-systems;
• the nature or method of production of the energy consumed by the infrastructures.
The present document provides an overview of the ETSI EN 305 174 series of standards together with a definition of
the common and generic aspects to which the other standards in the series conform.
Clause 2 and clause 3 contain references, definitions, symbols and abbreviations which relate to this part; similar
information will be included in the corresponding clauses of the other parts, thus ensuring that each document can be
used on a "stand-alone" basis.
Clause 4 describes the network sub-systems applicable to broadband infrastructures and their interconnections that are
addressed by the ETSI EN 305 174 series.
Clause 5 specifies the format of the other parts of the ETSI EN 305 174 series (other than ETSI EN 305 174-8 [i.6]).

ISDN is not considered to be a broadband technology and is not addressed in the present document. cable access network: access network provided by cable operators comprising optical fibre and metallic cabling providing direct connection to customer premises core network: functional elements (that is equipment and infrastructure) that enable communication between operator sites (OSs) or equivalent ICT sites customer network: functional elements (that is equipment and infrastructure) that enable communication between a network interface unit (NIU), network termination point (NTP) or external network interface (ENTI), as appropriate, and one or more pieces of terminal equipment (TE) Customer Premises (CP): any location which is the sole responsibility of the customer End-of-Life (EoL): established point in a product life cycle after a period of primary use and at which a decision is required with regard to reuse, recycling or disposal end-use IT equipment: terminal equipment (TE) of a fixed access network, user equipment (UE) of a mobile access network or network interface unit (NIU) of a cable access network SIST EN 305 174-1 V1.1.1:2018

ETSI ETSI EN 305 174-1 V1.1.1 (2018-02) 10 External Network Test Interface (ENTI): point in or near the customer premises (inside or outside the customer network) accessible to the fixed access network operator for testing purposes Fibre Node (FN): device which performs a media conversion between an optical fibre cable link and a coaxial cable link in a cable access network fixed access network: access network provided by telecommunications operators comprising optical fibre and metallic cabling providing direct connection to customer premises ICT equipment: equipment providing data storage, processing and transport services NOTE: A combination of Information Technology Equipment and Network Telecommunications Equipment. ICT site: site containing structures or group of structures dedicated to the accommodation, interconnection and operation of ICT equipment 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 Information Technology Equipment (ITE): equipment providing data storage, processing and transport services for subsequent distribution by network telecommunications equipment (NTE) Last Operators Connection point (LOC): interface to the fixed access transport networks of one or more operators from which cabling is routed to a customer network mobile access network: telecommunications network in which the access to the network (connection between user equipment and network) is implemented over the air interface Network Data Centre (NDC): data centre embedded within the core network NOTE: A network data centre of a cable access network may be termed a master head-end. Network Distribution Node (NDN): grouping of NTE equipment within the boundaries of an access network providing distribution of service from an operator site (OS) NOTE: Where all the Network Telecommunications Equipment (NTE) at a given location is under common governance, any supporting infrastructure for power distribution and environmental control together with the necessary levels of resilience and security required to provide the desired service availability is included as part of the NDN.
