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]).

The customer premises may take a number of forms. As detailed in clause 4.4 the subscriber may be residential or
commercial and may be within single-tenanted or multi-tenanted premises. It is also necessary to distinguish between
the access provider, who is responsible for the design, operation and maintenance of the access network, and the service
provider that provides the service carried to the subscriber by the access network. These two entities may be different. A
given access network may support multiple service providers.
4.1.2 Energy management
Broadband provision is an enabling technology capable of supporting a reduction of global energy consumption (for
example, by providing facilities such as home working and video conferencing to reduce travel demands). For this
reason, it may not be the case that the total energy consumption of broadband networks will be reduced, though the
application of effective energy efficiency measures will minimize any increases due to predicted service evolution.
The scale of reductions in energy consumption and/or improvements of energy efficiency is:
• dependent on the network sub-systems;
• generally greater at the design stage rather than following improvements to existing infrastructures.
The potential reductions in energy consumption and/or improvements of energy efficiency in ICT sites as described in
clause 4.2 are expected to be substantial but apply in only a relatively small number of locations and may prove vital
where availability of power is restricted. These clearly defined premises are provided with appropriate Key
Performance Indicators (KPIs) to determine relative performance levels in terms of energy efficiency.
By comparison to ICT sites the saving at the various network distribution nodes and within the cabling infrastructures
of the individual access networks may be very much smaller but the aggregation of those saving may outweigh the
energy efficiency gains elsewhere due to the very large number of customers, thus justifying their consideration and
implementation. The communities served by customer networks are the recipients of the "energy efficiency enabling"
technologies provided by broadband services and the relevant parts of this multi-part deliverable serves to indicate
strategies/approaches that maximize the opportunities

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).

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]).

The customer premises may take a number of forms. As detailed in clause 4.4 the subscriber may be residential or
commercial and may be within single-tenanted or multi-tenanted premises. It is also necessary to distinguish between
the access provider, who is responsible for the design, operation and maintenance of the access network, and the service
provider that provides the service carried to the subscriber by the access network. These two entities may be different. A
given access network may support multiple service providers.
4.1.2 Energy management
Broadband provision is an enabling technology capable of supporting a reduction of global energy consumption (for
example, by providing facilities such as home working and video conferencing to reduce travel demands). For this
reason, it may not be the case that the total energy consumption of broadband networks will be reduced, though the
application of effective energy efficiency measures will minimize any increases due to predicted service evolution.
The scale of reductions in energy consumption and/or improvements of energy efficiency is:
• dependent on the network sub-systems;
• generally greater at the design stage rather than following improvements to existing infrastructures.
The potential reductions in energy consumption and/or improvements of energy efficiency in ICT sites as described in
clause 4.2 are expected to be substantial but apply in only a relatively small number of locations and may prove vital
where availability of power is restricted. These clearly defined premises are provided with appropriate Key
Performance Indicators (KPIs) to determine relative performance levels in terms of energy efficiency.
By comparison to ICT sites the saving at the various network distribution nodes and within the cabling infrastructures
of the individual access networks may be very much smaller but the aggregation of those saving may outweigh the
energy efficiency gains elsewhere due to the very large number of customers, thus justifying their consideration and
implementation. The communities served by customer networks are the recipients of the "energy efficiency enabling"
