Foreword This Group Specification (GS) has been produced by ETSI Industry Specification Group (ISG) Operational energy Efficiency for Users (OEU). Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should

Introduction Fu
19、rther to the 1997 Kyoto protocol i.6, the European Commission issued Directives in order to improve the energy consumption of telecommunication services. Fixed Broadband Access constitutes one of the most important ICT areas of energy consumption. Therefore suppliers and users of information and com
20、munication technology (ICT) equipment are obliged to implement “Green“ tools (meters, indicators) to monitor the energy efficiency of their networks. The main target of ETSI ISG OEU is the development of the present document defining appropriate energy consumption measurements for operational techni
21、cal equipment of copper and optical access loop as well as technical Measurement Key Performance Indicators (KPIs) to be used for operational Fixed Access Network. The present document has been developed by ISG OEU members and is supported by the CTO Alliance/CRIP to define the most efficient tools.
22、 It is expected that the present document will influence the development of new specifications on energy consumption, measurements of operational technical equipment of copper and optical fixed access under the responsibility of ETSI TC EE. Several standards and technical documents have been taken i
23、nto account during the development of the present document including EC Mandate M/462 i.1, ETSI ES 203 215 V1.2.1 1, JCGM 100:2008 2, ETSI TS 105 174-1 i.2, ETSI TS 105 174-4-1 i.3, ETSI TS 105 174-5-1 i.4 EC DG JRC Code of Conduct for Broadband Networks i.5, and Kyoto Protocol i.6.

24、 002 V1.1.1 (2015-06)5 1 Scope The present document proposes Key Performance Indicators (KPI) applicable by vendors in laboratories or by operators in operational situations. The scope of the present document is exclusively dealing with the Multi-Service Access Node MSAN, configured for both Fiber t
25、o the Home (FTTH) and Digital subscriber line (DSL) usages. Considering the foreseen implementation of energy consumption meters embedded in the MSAN allowing real time knowledge of energy consumption, clause 4 proposes the operational KPIs which should be managed by the Network Management System (N
26、MS). The present document proposes engineering KPIs to evaluate and to model on-field energy consumption. The present document is structured in three clauses: 1) Listing the key parameters which have most impact on the power consumption. 2) Defining a MSAN power consumption model when it is used as
27、a digital subscriber line access multiplexer (DSLAM) to obtain a green Operational KPI, according to the key parameters. 3) Defining the methodology for an optical line termination (OLT). To be noted: The DSLAM is a Digital Subscriber Line Access Multiplexer that could be split in three sets: ATM DS
28、LAM: A DSLAM with an internal ATM bus (which supports xDSL services). IP DSLAM: A DSLAM with an internal IP bus. GE DSLAM: Equipment with GE uplink card. The OLT (Optical Line Termination) is an equipment with internal IP bus which provides FTTH services. The MSAN which is an equipment with internal
29、 IP BUS, provides either DSL services or POTS services or GPON services or any mix together. Figure 1: Definition of nodes In the present document, only the following terms will be used: DSLAM, OLT and MSAN.
