Foreword
This Technical Report (TR) has been produced by ETSI Technical Committee Access, Terminals, Transmission and
Multiplexing (ATTM).
The present document is part 5-1 of a multi-part deliverable. Full details of the entire series can be found in part 1 [i.36].
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 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. It is therefore important to maximize the energy efficiency of
all the network elements necessary to deliver the required services.
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 present document is part 5-1 of a multi-part deliverable which has been produced by ETSI Technical Committee
Access, Terminals, Transmission and Multiplexing (ATTM) in close collaboration with CENELEC via the Co-
ordination Group on Installations and Cabling (CGIC). It offers a contribution to the required standardization process by
establishing an initial basis for work on ICT networks and transmission engineering, with active collaboration from a
number of other ETSI and CENELEC Technical Bodies. When complete, the documents will contain information that
has been jointly evolved to present developments in installations and transmission implementation, and describing their
progress towards energy efficiency in Next Generation Networks (NGN).

1 Scope
The present document details measures which may be taken to improve the energy efficiency within homes
(single-tenant) by virtue of broadband deployment. Clauses 2 and 3 contain references, definitions 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.
Within the present document:
• clause 4 describes the nature of customer premises networks in homes (single tenant), defines the interfaces to
those networks and identifies the standardization bodies working on the design and installation of those
networks;
• clause 5 describes the strategies that may be employed within homes (single tenant) to both increase the
energy efficiency of installed information technology equipment and to use the facilities offered by
information technology services to reduce overall energy consumption.
This will enable the proper implementation of services, applications and content on an energy efficient infrastructure,
though it is not the goal of this multi-part deliverable to provide detailed standardized solutions for home broadband
network architecture.

4 Customer networks in homes (single-tenant)
4.1 Overview of home network infrastructures
4.1.1 General
Homes, both as single-tenant and multi-tenant premises, are unique with respect to cabling infrastructures for the
following reasons:
• they represent the largest constituency for broadband services;
• there are limited or non-existent cabling infrastructures within the home for the distribution of external
network telecommunications services or internally generated information technology services;
• residents are either willing to physically move within the home, or install service-specific wireless systems to
access the primary telecommunications equipment;
• residents tend to situate their living space(s) according to the availability of the BCT service;
• the ongoing development of BCT services and the consequent requirements of the local cabling (HDMI etc.)
restrict distribution of those services within the home since a significant percentage of installations have been
changed by the user and which restrict the capability of the infrastructure to support upgraded services.
The growth of ICT applications within the home and the advent of broadband services allowing access to BCT services
using ICT applications has failed to encourage large scale installation of home cabling infrastructures as a means of
distribution since:
• aesthetic considerations have prominence in domestic premises;
• refurbishment of the building structures is uncommon;
• residents expect temporal flexibility in access to services.
Instead there has been a substantial investment in wireless infrastructures within the home. These systems lie outside
the scope of this multi-part document.
4.1.2 Network convergence
Within the home, telecommunications services fall into three groups:
• ICT (also referred to as HBES Class 2): for example, telephone, local area network;
ETSI
10 ETSI TR 105 174-5-1 V1.1.1 (2009-10)
• BCT (also referred to as HBES Class 3): for example, broadcast television;
• CCCB (also referred to as HBES Class 1): for example, security alarms, surveillance and door access control,
environmental controls.
Annex A includes details of the types of services and the group into which they fall.
Access networks providing ICT services are also supporting BCT and CCCB services using ICT applications. Access
networks providing BCT services also support ICT services using embedded ICT applications.
Within customer premises, the range of networks has, in the past, reflected the diversity of the services with:
• ICT services being delivered over a variety of cabling infrastructures ranging from those suitable only for
basic telephony through to those used for generic cabling (see clause 4.2.1);
• BCT services being delivered over application-specific coaxial cabling systems;
• CCCB services being delivered over a variety of cabling infrastructures ranging from application-specific
solutions described in general terms in clause 4.2.2, often including those combining power with control
systems, through to those used for generic cabling (see clause 4.2.1).
However, the network convergence seen in the access network may also extend into the customer premises. Within
customer premises, the opportunity for network convergence is further enhanced by the development of ICT networking
standards that support delivery of Power over Ethernet (PoE). These can typically provide approximately 13 W via
IEEE 802.3af [i.31] and approximately 25 W via IEEE 802.3at [i.32]) when using ICT applications such as
10/100/1000BASE-T.
The emergence and further development of PoE is expected to encourage the use of cabled infrastructure installations
since:
• both existing residents and developers of new homes will recognize the benefits of being able to control and
provide power to a wide range of equipment (for example, surveillance systems, door access control,
environmental control system) that can be managed from a central location and via a common infrastructure;
• residents will see an increase in equipment specified for connection to PoE without the need for external
power supplies and with a common connection style (EN 60603-7 series [i.37], also known as the RJ-45).
By these means, ICT applications, such as 10/100/1000BASE-T, are able to support ICT, BCT and CCCB services
within the home.
In order to meet the potential need for a common infrastructure to support network convergence within the home,
CENELEC TC215 developed EN 50173-4 [i.4], covering the design and specification of generic cabling.
4.2 Infrastructure standardization activities
4.2.1 Generic cabling designs in accordance with EN 50173-4
NOTE: EN 50173-4 [i.4], first published in 2007, has a similar scope to that of ISO/IEC 15018 [i.34] produced by
ISO/IEC JTC1 SC25. However, the two documents contain different requirements and are therefore not
identical at a technical level.
4.2.1.1 Infrastructure layers
EN 50173-4 [i.4] specifies two layers of infrastructure as shown in figure 1 (modified from EN 50173-4 [i.4]). Both
layers are fed from a Home Distributor (HD) or, if the dimensions of the home, its configuration or the complexity of
the network supports their use, Secondary Home Distributors (SHD) as shown in figure 2 (modified from
EN 50173-4 [i.4]). Figure 2 (modified from EN 50173-4 [i.4]) shows that generic cabling of EN 50173-4 [i.4] not only
provides distribution of broadband services delivered over cabled media via the access network but also supports the
reception of BCT services using antennae.
