Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpre

Introduction The increasing interaction between the different elements of the Information Communi

19、cation Technology (ICT) sector (hardware, middleware, software, services, etc.) supports the concept of convergence in which: a variety of multi-service packages can be delivered over a common infrastructure; a variety of infrastructures is able to deliver these packages; a single multi-service-pack

20、age may be delivered over several different infrastructures. As a result of this convergence, the development of new services, applications and content there is an increasing demand for bandwidth, reliability, quality and performance. The consequent increase in the demand for energy which implicatio

21、ns for cost and, in some cases, availability. It is therefore important to maximize the energy efficiency of network equipment at all levels. New technologies and infrastructure strategies are expected to enable operators to decrease the energy consumption, for a given level of service, of their exi

22、sting 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 4, sub-part 1 of a multi-part set which has been produced by ETSI Technical Committee Access, Terminals, Transmis

23、sion and Multiplexing (ATTM) in close collaboration with CENELEC via the Co-ordination Group on Installations and Cabling (CGIC). The document set offers a contribution to the required standardization process by establishing an initial basis for work on ICT networks and transmission engineering, wit

24、h active collaboration from a number of other ETSI and CENELEC Technical Bodies. When complete, the document set contains information that has been jointly evolved to present developments in installations and transmission implementation, and describing their progress towards energy efficiency in nex

25、t generation networks (NGN). ETSI ETSI TS 105 174-4-1 V1.2.1 (2015-09) 5 The present document analyses the work on Fixed Access Networks whilst details of each of the other parts of the document set can be found in Part 1 i.10. Clearly the energy efficiencies of Operator Sites, Data Centres, the Cor

26、e Networks and Customer Network Infrastructures are also important in maximizing the end-to-end energy efficiency of broadband communications and these issues are covered in other parts of the document set. However, Access Networks differ from the other network components in that they are likely to

27、include a very large number of locations each consuming a relatively low amount of energy. Not only do such small installations tend to be inefficient in their power utilization but when multiplied by their number, their total energy usage becomes considerable. Thus any energy saving which can be ac

28、hieved becomes significant when the number of sites is taken into account. ETSI ETSI TS 105 174-4-1 V1.2.1 (2015-09) 6 1 Scope The present document details measures which may be taken to improve the energy efficiency of access networks for broadband deployment. The present document: identifies the s

29、tandardization bodies working on diverse aspects of the access networks infrastructures interfaces, cabling, installation, operation, etc.; outlines some of the principal access network topographies and their differences in respect of energy consumption; provides strategic analysis of energy consump

30、tion trends within access networks. This enables the proper implementation of services, applications and content on an energy efficient infrastructure, though it is not the goal of the present document to provide detailed standardized solutions for network architecture. 2 References 2.1 Normative re
