Foreword
This Technical Report (TR) has been produced by ETSI Technical Committee Access, Terminals, Transmission and
Multiplexing (ATTM).
The present document is part 5-2 of a multi-part deliverable. Full details of the entire series can be found in part 1 [i.13].
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. 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 5-2 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 office premises
(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 office premises (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.
