Dostop, priključki, prenos in multipleksiranje (ATTM) - Upravljanje z energijo - Globalni ključni kazalniki uspešnosti (KPI) - Operativne infrastrukture - 2. del: Posebne zahteve - 2. poddel: Fiksna širokopasovna dostopovna omrežja
Ta dokument določa zahteve za globalni KPI za upravljanje z energijo (KPIEM) in njegove temeljne ciljne KPI-je, ki naslavljajo naslednje cilje za širokopasovna omrežja s fiksnim dostopom (FAN):
• poraba energije;
• učinkovitost opravil;
• obnovljiva energija.
Zahteve so preslikane v splošne zahteve ETSI ES 205 200-1 [1].
Upravljanje z energijo omrežij s fiksnim dostopom je sestavljeno iz več neodvisnih slojev. Ta dokument naslavlja učinkovitost infrastruktur, ki podpirajo običajno delovanje gostujoče opreme ICT znotraj fiksnega dostopovnega omrežja (npr. distribucija električne energije, okoljski nadzor, zaščita in varnost). Ta dokument ne naslavlja drugih slojev, kot so učinkovitost same opreme ICT, učinkovitost uporabe razpoložljive zmogljivosti procesorja,
in sloji, povezani s končno dostavljeno storitvijo (npr. potrebna zmogljivost procesorja glede na rezultat po elementih) ali prekrivni sloji (npr. poraba energije glede na rezultat po elementih).
Učinek na okolje in upravljanje različnih virov energije ne spadata na področje uporabe tega dokumenta.
KPIEM se lahko prilagodi posebnim zahtevam s spreminjanjem vrednotenja obnovljivih energij. Izračuni morajo temeljiti na značilnem vzorcu omrežnih elementov.
Globalni KPI ni zasnovan za samostojno primerjavo fiksnih omrežij. Fiksno omrežje ne opredeli kot dobro ali slabo, razen če se združi z drugimi parametri, ki se obravnavajo kot pomembni za primerjavo, kot so lokalne podnebne razmere, zahteve glede razpoložljivosti ali namen fiksnih omrežij.

Introduction
Energy costs continue to increase, a trend that will continue in the future, while broadband penetration is introducing
new active equipment to the network architecture. In this context, and to reflect other environmental aspects of
sustainability, it is vital that the main telecommunication actors implement effective general engineering of fixed and
mobile broadband networks and sites provisioning, managing or using those networks (i.e. operator sites, operator data
centres and customer data centres) in order to respond to critical issues of energy consumption while proposing essential
solutions to true broadband deployment. To guide this process, it is essential that metrics are defined, termed Global
Key Performance Indicators (KPI ), that enable energy usage to be managed more effectively.
EM
The ETSI ES 205 200 series of standards comprises:
• ETSI ES 205 200-1 [1]: a generic requirements document addressing Global KPIs for operational
infrastructures;
NOTE: Global KPIs do not address design/operation of components or subsystems of broadband deployment
networks.
• a sub-series ETSI ES 205 200-2 that defines the Global KPIs, and drives energy management targets, for
specific operational networks and sites and which describes how the Global KPIs are to be applied (which may
be used to support future regulatory objectives):
- ETSI ES 205 200-2-1 [i.11]: Data centres;
- ETSI ES 205 200-2-2 (the present document): Fixed broadband access networks;
- ETSI ES 205 200-2-3 [i.12]: Mobile access networks;
- ETSI ES 205 200-2-4 [i.13]: Cable Access Networks.
These documents do not define KPI limits or targets (which is outside the scope of the ETSI ES 205 200 series
of standards).
These documents will accelerate:
• availability of operational infrastructure architectures and network implementations that use energy more
efficiently;
• the definition and attainment of sustainability objectives for operational broadband networks.
Within the present document:
• clause 4 explains the definition of a Broadband access network in terms of the systems it comprises and the
boundaries that apply;
• clause 5 describes how the Objective KPIs of the present document meet the requirements of ETSI
ES 205 200-1 [1];
• clause 6 describes the specific requirements of the Global KPI and the supporting Objective KPIs for fixed
access networks;
• Annex A discusses the roles of different types of Key Performance Indicators i.e. Technical, Objective and
Global in relation to the overall energy management concepts of the present document.

1 Scope
The present document specifies the requirements for a Global KPI for energy management (KPI ) and their
EM
underpinning Objective KPIs addressing the following objectives for the fixed access networks (FANs) of broadband
deployment:
• energy consumption;
• task effectiveness;
• renewable energy.
The requirements are mapped to the general requirements of ETSI ES 205 200-1 [1].
Energy management of fixed access networks comprises a number of independent layers. The present document
addresses performance of infrastructures that supports the normal function of hosted ICT equipment within the fixed
access network (e.g. power distribution, environmental control, security and safety). The present document does not
address other layers such as performance of ICT equipment itself, performance of usage of available processing power,
and layers related to final service delivered (e.g. processing power required per itemized outcome) or overlay layers
(e.g. energy consumption required per itemized outcome).
The environmental impact and management of different energy sources are outside the scope of the present document.
KPI may be tailored for specific needs by changing weighting of renewable energies. Calculations should be based on
EM
a significant sample of network elements.
The Global KPI alone is not designed for comparison of fixed networks. It does not define a fixed network as good or
bad unless combined with other parameters considered relevant for a comparison, such as local climatic conditions,
availability requirements or purpose of fixed networks.

The present document considers:
• Figure 1 to be an effective basis for establishment of KPI and is consistent with the AN technologies defined
EM
in Recommendation ITU-T G.992.5 [i.5], Recommendation ITU-T G.984 [i.6], Recommendation ITU-T
G.987 [i.7], Recommendation ITU-T G.989 [i.8]) and Recommendation ITU-T G.993.2 [i.4].
• The term OS shown in Figure 1 represents the operator sites containing the fixed broadband access nodes,
under the generic name of FAN. It may be based on MSAN, DSLAM and OLT according to the access
technology.
For the purposes of energy management, the fixed broadband access network comprises all sites/elements between the
the OSes (included) and the LOCs (not included), as shown in Figure 1. Thus:
• There can be a simple FAN without NDN and the FAN will be in the OS.
• Or there can be several NDN between the OS and the LOC.
An OS could be located either indoors or at an outdoor site (in a street cabinet, for instance).

Introduction
Energy costs continue to increase, a trend that will continue in the future, while broadband penetration is introducing
new active equipment to the network architecture. In this context, and to reflect other environmental aspects of
sustainability, it is vital that the main telecommunication actors implement effective general engineering of fixed and
mobile broadband networks and sites provisioning, managing or using those networks (i.e. operator sites, operator data
centres and customer data centres) in order to respond to critical issues of energy consumption while proposing essential
solutions to true broadband deployment. To guide this process, it is essential that metrics are defined, termed Global
Key Performance Indicators (KPI ), that enable energy usage to be managed more effectively.
EM
The ETSI ES 205 200 series of standards comprises:
• ETSI ES 205 200-1 [1]: a generic requirements document addressing Global KPIs for operational
infrastructures;
NOTE: Global KPIs do not address design/operation of components or subsystems of broadband deployment
networks.
• a sub-series ETSI ES 205 200-2 that defines the Global KPIs, and drives energy management targets, for
specific operational networks and sites and which describes how the Global KPIs are to be applied (which may
be used to support future regulatory objectives):
- ETSI ES 205 200-2-1 [i.11]: Data centres;
- ETSI ES 205 200-2-2 (the present document): Fixed broadband access networks;
- ETSI ES 205 200-2-3 [i.12]: Mobile access networks;
- ETSI ES 205 200-2-4 [i.13]: Cable Access Networks.
These documents do not define KPI limits or targets (which is outside the scope of the ETSI ES 205 200 series
of standards).
These documents will accelerate:
• availability of operational infrastructure architectures and network implementations that use energy more
efficiently;
• the definition and attainment of sustainability objectives for operational broadband networks.
Within the present document:
• clause 4 explains the definition of a Broadband access network in terms of the systems it comprises and the
boundaries that apply;
• clause 5 describes how the Objective KPIs of the present document meet the requirements of ETSI
ES 205 200-1 [1];
• clause 6 describes the specific requirements of the Global KPI and the supporting Objective KPIs for fixed
access networks;
• Annex A discusses the roles of different types of Key Performance Indicators i.e. Technical, Objective and
Global in relation to the overall energy management concepts of the present document.

7 Final draft ETSI ES 205 200-2-2 V1.1.0 (2018-03)
1 Scope
The present document specifies the requirements for a Global KPI for energy management (KPI ) and their
EM
underpinning Objective KPIs addressing the following objectives for the fixed access networks (FANs) of broadband
deployment:
• energy consumption;
• task effectiveness;
• renewable energy.
The requirements are mapped to the general requirements of ETSI ES 205 200-1 [1].
Energy management of fixed access networks comprises a number of independent layers. The present document
addresses performance of infrastructures that supports the normal function of hosted ICT equipment within the fixed
access network (e.g. power distribution, environmental control, security and safety). The present document does not
address other layers such as performance of ICT equipment itself, performance of usage of available processing power,
and layers related to final service delivered (e.g. processing power required per itemized outcome) or overlay layers
(e.g. energy consumption required per itemized outcome).
The environmental impact and management of different energy sources are outside the scope of the present document.
KPI may be tailored for specific needs by changing weighting of renewable energies. Calculations should be based on
EM
a significant sample of network elements.
The Global KPI alone is not designed for comparison of fixed networks. It does not define a fixed network as good or
bad unless combined with other parameters considered relevant for a comparison, such as local climatic conditions,
availability requirements or purpose of fixed networks.

The present document considers:
• Figure 1 to be an effective basis for establishment of KPI and is consistent with the AN technologies defined
EM
in Recommendation ITU-T G.992.5 [i.5], Recommendation ITU-T G.984 [i.6], Recommendation ITU-T
G.987 [i.7], Recommendation ITU-T G.989 [i.8]) and Recommendation ITU-T G.993.2 [i.4].
• The term OS shown in Figure 1 represents the operator sites containing the fixed broadband access nodes,
under the generic name of FAN. It may be based on MSAN, DSLAM and OLT according to the access
technology.
For the purposes of energy management, the fixed broadband access network comprises all sites/elements between the
the OSes (included) and the LOCs (not included), as shown in Figure 1. Thus:
• There can be a simple FAN without NDN and the FAN will be in the OS.
• Or there can be several NDN between the OS and the LOC.
An OS could be located either indoors or at an outdoor site (in a street cabinet, for instance).

1 Scope
The present document specifies the requirements for a Global KPI for energy management (KPI ) and their
EM
underpinning Objective KPIs addressing the following objectives for the fixed access networks (FANs) of broadband
deployment:
• energy consumption;
• task effectiveness;
• renewable energy.
The requirements are mapped to the general requirements of ETSI ES 205 200-1 [1].
Energy management of fixed access networks comprises a number of independent layers. The present document
addresses performance of infrastructures that supports the normal function of hosted ICT equipment within the fixed
access network (e.g. power distribution, environmental control, security and safety). The present document does not
address other layers such as performance of ICT equipment itself, performance of usage of available processing power,
and layers related to final service delivered (e.g. processing power required per itemized outcome) or overlay layers
(e.g. energy consumption required per itemized outcome).
The environmental impact and management of different energy sources are outside the scope of the present document.
KPI may be tailored for specific needs by changing weighting of renewable energies. Calculations should be based on
EM
a significant sample of network elements.
The Global KPI alone is not designed for comparison of fixed networks. It does not define a fixed network as good or
bad unless combined with other parameters considered relevant for a comparison, such as local climatic conditions,
availability requirements or purpose of fixed networks.
