35、verables except when used in direct citation. 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 deli
36、vered 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
37、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 s
38、ervices. 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 onl
39、y standards can produce. The present document is part 2 of a multi-part deliverable which has been produced by ETSI Technical Committee Access, Terminals and Transmission, Multiplexing (ATTM) in close collaboration with CENELEC via the Co-ordination Group on Installations and Cabling (CGIC). It offe
40、rs a contribution to the required standardization process by establishing an initial basis for work on ICT general engineering, with active collaboration from a number of other ETSI and CENELEC Technical Bodies. ETSI ETSI TS 105 174-2 V1.2.1 (2017-01)7 When complete, the multi-part deliverable will
41、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). In order to monitor the implementation and operation of energy efficient broadband de
42、ployment, the present document also discusses Data processing and Communication Energy Management (DCEM) for energy efficiency and focus on the possible consequences of standardization of installations, cabling techniques and equipment. In particular, the study will investigate possibilities and sug
43、gest solutions for development of processes for optimization in installation techniques and energy consumption. ETSI ETSI TS 105 174-2 V1.2.1 (2017-01)8 1 Scope The present document details measures which may be taken to improve the energy efficiency within ICT sites for broadband deployment. Clause
44、s 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 introduces ICT sit
45、e concepts including those specifically related to network operators; clause 5 develops the concept of Data processing and Communication Energy Management (DCEM), introduced in ETSI GS OEU 001 i.2; clause 6 details the approaches that may be employed to improve energy efficiency within the informati
46、on technology infrastructure; clause 7 details the approaches that may be employed to improve energy efficiency within the communication technology infrastructure; clause 8 details the approaches that may be employed to improve energy efficiency within the environmental control systems; clause 9 det
47、ails the approaches that may be employed to improve energy efficiency within the power distribution system; clause 10 details the approaches that may be employed to improve energy efficiency within the physical infrastructure; clause 11 provides a summary of energy efficiency approaches within ICT s
48、ites; annex A provides indications of the first order effect of applying the approaches outlined in clauses 6, 7 and 9; annex B contains the recommendations of the present document. This will enable the proper implementation of services, applications and content on an energy efficient infrastructure
49、, though it is not the goal of this multi-part deliverable to provide detailed standardized solutions for network architecture. The present document focuses on energy efficiency. The CO2footprint is not taken in account to the present document but in the near future a regulation on CO2footprint will be will be created. Two separate aspects of energy efficiency are considered as shown in figure 1: actions to improve energy efficiency in existing ICT sites in the short or medium term; actions to improve energy efficiency in new ICT sites, in mediu
