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 the 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.
The 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 5, sub-part 1 of a multi-part deliverable and specifies requirements for customer network
infrastructures within homes (single-tenant) as recipients of broadband deployment in response to the increasing amount
of ICT equipment and demand for services. As energy costs in homes continues to rise, strategies are required to
optimize energy consumption of all segments of ICT.
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 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.
The present document specifies the requirements for resource management of customer network infrastructures within
homes (single-tenant), as recipients of broadband services, as a combination of:
• Energy management while maintaining or even improving the level of service is supported by requirements
for:
i) in new, refurbished and existing buildings: the selection of customer premises equipment and associated
power supplies which meet specific energy consumption and energy efficiency requirements (by means
of external references);
ii) in new or refurbished buildings: the provision of appropriate spaces and pathways to accommodate
cabling infrastructure.
• EoL of ICT equipment by reference to ETSI EN 305 174-8 [7].

4.1 Broadband deployment to customer premises
4.1.1 General
Figure 1 is a technology-agnostic diagram depicting a segment of a broadband network showing the interconnection of
ICT sites and customer premises installations for fixed (broadband) and cable access networks. In principle, every
operator network can contain any number of each of these elements and may be connected to any number of other
operator networks.

Figure 1: Network sub-systems of fixed broadband access network infrastructure
Broadband provision is an enabling technology capable of supporting a reduction of global energy consumption (for
example, by providing facilities such those listed in Table 1 which may reduce the demand for travel). This requires an
increasing amount of ICT equipment that often needs to be always active (and consuming energy). 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
ETSI EN 305 174-2 [i.13] are expected to be substantial but apply in only a relatively small number of locations
(i.e. Operator Sites (OS) and Network Data Centres (NDC)) and may prove vital where availability of power is
restricted at those locations. These clearly defined premises are provided with appropriate Key Performance Indicators
(KPIs) to determine relative performance levels in terms of energy management (see ETSI EN 305 200 series [i.14]).
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 savings 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 presented.
Within customer premises, it is generally the customer rather than the operator that funds the energy costs. Potential
reductions in energy consumption may well be identifiable in design terms but they are generally not individually
quantifiable due to the diversity of customer networks.

4.1.2 Telecommunications services within homes
Historically, telecommunications services within homes (and customer premises in general) have been grouped as:
• Broadcast Communications Technology (BCT);
• Command, Control and Communications in Buildings (CCCB);
• Information Communications Technology (ICT).
It is important to differentiate between the "service" delivered in the home and the "application" used to deliver it.
EXAMPLE: Many people receive television (a BCT service) via their personal computers or tablet device using
wired or wireless Ethernet connection (an ICT application). Similarly, homes connected to cable
access networks may use DOCSIS (a BCT application) to communicate data (an ICT service).
However within the home, the distribution of the ICT services within DOCSIS is generally
implemented via an ICT application.
Until recently, CCCB services have been dominated by CCCB applications which have tended to be proprietary with
each one implemented using a particular infrastructure design. The reluctance of the CCCB industry to adopt a common
infrastructure has restricted the concept of pre-cabling within homes - which is a foundation of the generic cabling
concept adopted by both BCT and ICT applications.
The extension of Ethernet applications to support remotely powered devices - using the standardized 4-pair balanced
cabling infrastructure already specified for ICT applications - has resulted in a massive increase in the number of
services that the ICT applications can support. Future developments include the use of 1-pair applications, also
providing remote powering, which will allow support for devices to support the "Internet of Things" and which are
integral to Sustainable Digital Multi-Service ("Smart") City concepts.
This convergence of delivery of ICT and CCCB services using common applications and a common cabling
infrastructure provides the opportunity for the holistic management of the entire home environment - including energy
management.
An extension of this convergence between ICT and CCCB services is now recognized, particularly within the home,
within the concepts of Internet of Things and Smart Home (IoT-SH) as described in HGI-GD035 [i.24].
As can be seen in Table 1, BCT applications are restricted to the delivery of BCT services by virtue of their coaxial
cabling background - but are important due to their dominance in the market. IoT services are generally delivered using
ICT applications whereas SH services may be delivered using ICT applications or specific SH applications (as reflected
in the contents of Table 1). However, it is expected that the majority of IoT-SH services will b

ETSI ETSI EN 305 174-5-1 V1.3.1 (2018-07)8 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 the 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. The 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 5, sub-part 1 of a multi-part deliverable and specifies requirements for customer network infrastructures within homes (single-tenant) as recipients of broadband deployment in response to the increasing amount of ICT equipment and demand for services. As energy costs in homes continues to rise, strategies are required to optimize energy consumption of all segments of ICT. 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).

Figure 1: Network sub-systems of fixed broadband access network infrastructure Broadband provision is an enabling technology capable of supporting a reduction of global energy consumption (for example, by providing facilities such those listed in Table 1 which may reduce the demand for travel). This requires an increasing amount of ICT equipment that often needs to be always active (and consuming energy). 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 ETSI EN 305 174-2 [i.13] are expected to be substantial but apply in only a relatively small number of locations (i.e. Operator Sites (OS) and Network Data Centres (NDC)) and may prove vital where availability of power is restricted at those locations. These clearly defined premises are provided with appropriate Key Performance Indicators (KPIs) to determine relative performance levels in terms of energy management (see ETSI EN 305 200 series [i.14]). 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 savings 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 presented. Within customer premises, it is generally the customer rather than the operator that funds the energy costs. Potential reductions in energy consumption may well be identifiable in design terms but they are generally not individually quantifiable due to the diversity of customer networks.

It is important to differentiate between the "service" delivered in the home and the "application" used to deliver it. EXAMPLE: Many people receive television (a BCT service) via their personal computers or tablet device using wired or wireless Ethernet connection (an ICT application). Similarly, homes connected to cable access networks may use DOCSIS (a BCT application) to communicate data (an ICT service). However within the home, the distribution of the ICT services within DOCSIS is generally implemented via an ICT application. Until recently, CCCB services have been dominated by CCCB applications which have tended to be proprietary with each one implemented using a particular infrastructure design. The reluctance of the CCCB industry to adopt a common infrastructure has restricted the concept of pre-cabling within homes - which is a foundation of the generic cabling concept adopted by both BCT and ICT applications. The extension of Ethernet applications to support remotely powered devices - using the standardized 4-pair balanced cabling infrastructure already specified for ICT applications - has resulted in a massive increase in the number of services that the ICT applications can support. Future developments include the use of 1-pair applications, also providing remote powering, which will allow support for devices to support the "Internet of Things" and which are integral to Sustainable Digital Multi-Service ("Smart") City concepts. This convergence of delivery of ICT and CCCB services using common applications and a common cabling infrastructure provides the opportunity for the holistic management of the entire home environment - including energy management. An extension of this convergence between ICT and CCCB services is now recognized, particularly within the home, within the concepts of Internet of Things and Smart Home (IoT-SH) as described in HGI-GD035 [i.24]. As can be seen in Table 1, BCT applications are restricted to the delivery of BCT services by virtue of their coaxial cabling background - but are important due to their dominance in the market. IoT services are generally delivered using ICT applications whereas SH services may be delivered using ICT applications or specific SH applications (as reflected in the contents of Table 1). However, it is expected that the majority of IoT-SH services will be delivered using ICT applications. As a result, ICT applications are capable of support all the service types and standards have been developed to specify the design and installation of generic cabling for these applications (see clause 5). For this reason, clause 6 of the present document focuses on the following aspects: • the planning of pathways and spac
