Introduction
ICT energy needs and costs will continue to increase in the future, while new fixed generations will be deployed and
will introduce new active dedicated equipment in the global network architecture.
In this context, and to reflect environmental aspects of sustainability, it is essential for telecommunications network
operators to implement effective general engineering of fixed broadband networks and sites provisioning, managing or
using those networks (i.e. ICT sites) in order to respond to critical issues of energy consumption. To guide this process,
it is essential that metrics are defined that enable energy usage to be managed more effectively.
The Global Key Performance Indicators (KPIs) of the ETSI EN 305 200 series [1] address operational infrastructures
and do not consider design or operation of individual components comprising those infrastructures.
The present document specifies the deployment of Global KPIs for energy management (KPIEM) for the fixed access
networks of broadband deployment specified in ETSI EN 305 200-2-2 [2].
The fixed access network described in ETSI EN 305 200-2-2 [2] includes all the active components or parts of the
access network.

1 Scope
The reporting of Global KPIs in accordance with ETSI EN 305 200-2-2 [2] requires the collection of data to enable the
calculation of the following aspects:
• Objective KPI relating to task efficiency (KPI ) based on data_volume and total energy consumption (KPI ).
TE EC
• Objective KPI relating to the use of renewable energy (KPI ).
REN
The present document supports the requirements of ETSI EN 305 200-2-2 [2] providing a framework for, and detailing,
the implementation procedures including any necessary techniques for estimation of energy consumption together with
clarification and treatment of different types of data volume.

Figure 1: Fixed access network implementations
Within the Fixed Access Network (FAN), the term Network Distribution Node (NDN) is employed to describe a variety
of aggregations of Network Telecommunications Equipment (NTE) at locations between the Operator Site (OS) and the
Terminal Equipment (TE) in the Customer Premises (CP).
The Last Operator Connection point (LOC) is shown as a specific example of an NDN and is the closest NDN
containing NTE to a CP.
Figure 1 shows certain NDNs within dashed boxes to indicate that they are:
• optional;
• not restricted in number to the configurations shown.
4.2 KPIs for energy management
4.2.1 Global KPI (KPI ) for fixed access networks
EM
From ETSI EN 305 200-2-2 [2], KPI is a combination of two separate KPIs, in a common assessment period, as
EM
follows:
1) the Objective KPI for task effectiveness expressed as KPI (see clause 4.2.2.2);
TE
2) the Objective KPI for renewable energy contribution expressed as KPI (see clause 4.2.2.3);
REN
and both of these Objective KPIs incorporate a third Objective KPIs for energy consumption expressed as KPI (see
EC
clause 4.2.2.1).

From ETSI EN 305 200-2-2 [2], KPI is defined as:
EM
data _ volume
in conjunction with KPI
REN
KPI =
TE

EC
The Global KPI, KPI , and the underpinning Objective KPIs are primarily intended for trend analysis - not to enable
EM
comparison between fixed access networks.
4.2.2 Objective KPIs
4.2.2.1 Energy consumption (KPI )
EC
4.2.2.1.1 General
The present document supports the evaluation of the energy consumption required to provide a given level of service as
a primary objective.
From ETSI EN 305 200-2-2 [2], KPI , for a given assessment period, is defined mathematically as:
EC

∑ ∑
 =+

where, for the assessment period:
i = index of OS
j = index of NDN sites
N = total number of OS
M = total number of NDN sites
C
= energy consumption of all the fixed access network NTE at OS
i
OS
i
NOTE 1: C includes the energy consumption of the supporting infrastructure at OSs where all the NTE is under
OS
common governance.
C = energy consumption of all the fixed access network NTE at NDN supplied from the utility, from
j
NDN
j
upstream sources or generated on-site
NOTE 2: C includes the energy consumption of the supporting infrastructure at NDNs where all the NTE is
NDN
under common governance.
The note text in the explanations of the parameters are taken from ETSI EN 305 200-2-2 [2]. However, it should be
noted that network and location sharing (see clause 5.2.1.5) implies that not all NTE at OS and NDN sites is under
common governance and the present document refines the approach taken in such situations.
The above formula and terms do not take account of equipment that is powered by third parties including Access
Gateways (AG), Fiber To The distribution point (FTTdP) equipment (G-FAST) and Optical Network Termination
(ONT) equipment powered by the end-user. This is not addressed in ETSI EN 305 200-2-2 [2] and the inclusion of such
equipment requires a modification to the above formula (see clause 4.2.2.1.2).
It has to be considered that a fixed access network is complex and consists of a large number of distributed sites
accommodating ultra-broadband equipment. A typical Operator has many thousand sites, up to tens of thousands. The
number of sites is predicted to increase further with the development of higher speed networks such as G-FAST and of
Fixed Wireless Access (FWA).
KPI can be either measured or estimated:
EC
• KPI is the energy consumption obtained through direct measurement by the MNO or electricity
EC-measured
supplier, or provided by another MNO if equipment is co-located in the OS or the NDN;
ETSI

---------------------- Page: 12 ----------------------
13 ETSI TS 105 200-2-2 V1.3.1 (2019-12)
• KPI is the energy consumption obtained through direct measurement by the MNO or electricity
EC-estimated
supplier, or provided by another MNO if equipment is co-located in the OS or the NDN.
NOTE 3: This is applied in mixed, "access/core", network sites where equipment of other network segments is
present (core, fixed access, etc.) and the energy split is not made through continuous measurement.
Estimation is also needed for the energy consumed by network equipment in small cells, powered from
CP as described in clause 4.2.2.1.2.
4.2.2.1.2 CP-powered equipment within the calculation of KPI
EC
4.2.2.1.2.1 General
The presence of CP-powered equipment within the fixed access network requires an amendment of the formula for
KPI of clause 4.2.2.2.1 as follows:
EC

 = ∑+ ∑+

with:

= ∑


where, for the assessment period:
k = index of AG, FTTdp and ONT equipment
P = total number of AG, FTTdp, ONT equipment under consideration
= energy portion of the consumption of CP-powered AG, FTTdp, FTTH ONT or FWA equipment k

(see clauses 4.2.2.1.2.2, 4.2.2.1.2.3, 4.2.2.1.2.4, 4.2.2.1.2.5 and 4.2.2.1.2.6 respectively)
4.2.2.1.2.2 AG FXS VoIP
The progressive trend towards the dismission of legacy narrowband platforms (the digital switches) should be
considered.
The digital switches represent the majority of the energy consumption of many operators. They are coming of age as
they were installed in the early "nineties". Furthermore, the progressive use of broadband services, of Voice over IP
(VoIP) and of mobile telephony for voice calls has drastically reduced the number of customers to these legacy services.
Switching off the digital switches can produce huge reduction in energy use of fixed access networks.
Although drastically reduced, Public Switched Telephone Network (PSTN) is still widely used (elderly people, Point of
Sale (PoS) equipment, alarms, etc.). It is then normal to replace the original service from the digital switch with VoIP
delivery via the Foreign eXchange Service (FXS) port of an AG. Such provision of the PSTN service needs the
following considerations:
• the AG needs to be always on. It cannot be switched off when broadband service is not in use;
• the energy to support such service is provided by the customer (legacy equipment was powered by the
operator);
• "lifeline" service can be a problem. Need to install an opportune power backup (e.g. UPS) at the AG in case
lifeline service needs to be guaranteed.
The consumption of such equipment even if it is not directly accounted for by the operator, has an integral role in
providing the fixed access network services and should be part of the KPI .
EC
The AG module dedicated to the delivery of VoIP via FXS needs to remain active at all times and its consumption can
be estimated as 25 % of the maximum AG energy consumption (as specified in the equipment's technical specification).
