ETSI ES 203 184 V1.1.1 (2012-12) - Environmental Engineering (EE); Measurement Methods for Power Consumption in Transport Telecommunication Networks Equipment
ETSI ES 203 184 V1.1.1 (2013-03) - Environmental Engineering (EE); Measurement Methods for Power Consumption in Transport Telecommunication Networks Equipment
kSIST prES 203 184 V1.1.1:2013 is the SIST version of ETSI ES 203 184 V1.1.1 from ETSI. It specifies how to describe transport telecommunication network equipment, how to measure its power consumption, and how to calculate the Equipment Energy Efficiency Ratio (EEER). Engineers, test labs, quality teams and buyers can use it to compare equipment at the same functional level, at equipment level rather than node or network level.
What does kSIST prES 203 184 V1.1.1:2013 specify?
kSIST prES 203 184 V1.1.1:2013 specifies the metric, the test conditions and the methodology for EEER of transport equipment. It covers wired transport equipment used in telecommunications, mainly at OSI level 1 and also some OSI level 2 transport equipment such as MPLS-TP, but only at equipment level.
The scope includes transport systems connected by copper or fiber and excludes radio or wireless transport interfaces. In practice, that means the document is aimed at equipment such as SDH, OTN and DWDM transport products, not at wireless backhaul systems or network-level assessments.
The document is organized into seven clauses and two informative annexes. Clause 4 defines how to describe a system, clause 5 defines a system configuration, clause 6 defines EEER, and clause 7 defines the measurement method. Annex A gives worked examples of EEER evaluation, and Annex B lists bibliography.
| Annex | What it covers |
|---|---|
| Annex A | Informative examples of EEER evaluation for an optical amplifier and a ROADM WSS-based system |
| Annex B | Informative bibliography |
What are the key requirements of kSIST prES 203 184 V1.1.1:2013?
System description and configuration
Clause 4 requires an implementation-independent System Description. A System Description identifies the system category, the equipment type, capacity, interfaces, redundancy, other functions and expansion needs. This matters because the same product family can be built in several ways, and the EEER has to be tied to a clear functional description.
Clause 4 also defines three system categories. Category A covers terminal and signal conditioning equipment, Category B covers switch and ADM equipment without tributary add/drop ports, and Category C covers switch and ADM equipment with tributary add/drop ports. That distinction matters because Category C counts both network and tributary ports when capacity is calculated.
Clause 5 defines a System Configuration as one physical implementation of a System Description. If no System Description is available, the configuration has to meet basic utilization rules: the system must be used at least at 80 % of nominal capacity, and Category C equipment must allocate at least 20 % of that utilization to tributary ports. For a buyer or test lab, this prevents efficiency claims based on unrealistically empty systems.
Clause 5 also requires one card of each type when applicable, and redundancy cards must be provided according to the equipment maker’s recommended resiliency scheme. Common parts such as control, fan and power modules must be sufficient for the stated capacity, and expansion parts should be easy to add later. For optical amplifiers, the configuration uses the highest-power amplifier.
EEER calculation
Clause 6 defines EEER as total capacity divided by power consumption, with units of Mbps/W. For Category C equipment, both network and tributary ports count in the capacity figure. The practical meaning is simple: a higher EEER indicates more capacity delivered per watt.
Clause 6 also gives a gain-adjusted EEER for optical amplifiers. This variant multiplies capacity by optical amplifier gain before dividing by power, so equipment with the same functional configuration but different gain can be compared more fairly. That is useful when amplifier gain changes the usable reach of the system.
For Variable Bit Rate (VBR) interfaces, clause 6 uses power measurements at 0 %, 50 % and 100 % traffic load and averages the results. The document also applies the complete IMIX packet mix to VBR load. In practice, this makes the measurement reflect different packet sizes and processing effort, not just a single traffic pattern.
Measurement conditions
Clause 7.1 sets the laboratory conditions for power measurement. Measurements are made in a controlled room environment, with defined temperature, humidity and atmospheric pressure limits. The equipment must be powered from a stable source, with specific DC or AC test voltages depending on the supply type.
Clause 7.1 also sets quality requirements for the measuring setup. Instruments must be calibrated, within their calibration date and within ±1 % tolerance. The power source must be able to supply at least 1.5 times the equipment power rating, and AC power instruments need sufficient sample rate, bandwidth and waveform handling capability. In practice, this reduces the risk of underpowered tests or inaccurate readings.
Fixed and flexible methods
Clause 7.2 defines the Fixed configuration method. The power consumption is measured on the whole system as built, under the clause 7.1 conditions. This method matches the Certified TEER model referenced from ATIS.
Clause 7.3 defines the Flexible configuration method. Here, the power consumption of known subparts is measured separately and then summed for the chosen configuration. This method is useful when a manufacturer wants to evaluate several system builds without testing every complete system, and it matches the Declared TEER model referenced from ATIS.
Clause 7.3.1 sets the rules for subpart measurements. Fan modules are measured at full load, power modules at rated power and other common parts at full load. That makes the flexible result conservative, meaning it should not understate the expected consumption of the complete system.
What terms does kSIST prES 203 184 V1.1.1:2013 define?
- Equipment Energy Efficiency Ratio (EEER) - the ratio of total capacity to power consumption, used to compare transport equipment efficiency.
- System Description - an implementation-independent definition of the transport system, including category, type, capacity, interfaces and expansion.
- System Configuration - one physical realization of a System Description, such as a rack or multi-rack build.
- Variable Bit Rate (VBR) - traffic whose power draw can vary with load, so the test uses several load points and an average.
- Constant Bit Rate signal (CBR) - traffic treated as constant at its nominal load during the EEER calculation.
- Reconfigurable OADM (ROADM) - an add/drop optical node that can be changed by control or management commands.
- IMIX - the packet-size mix used for VBR load testing, so the measurement reflects realistic traffic diversity.
Who uses kSIST prES 203 184 V1.1.1:2013?
kSIST prES 203 184 V1.1.1:2013 is used by transport equipment manufacturers, test laboratories, network operators and procurement teams. Manufacturers use it to define a valid system description, choose a fixed or flexible configuration, and publish an EEER value for products such as optical amplifiers, WDM terminals, ROADMs, SDH/OTN equipment and packet transport switches.
Quality managers and buyers use it to compare equipment on a consistent basis. Lab teams use it to set up the power test, select the correct load condition for CBR and VBR interfaces, and document the resulting EEER. It is also relevant for multi-service transport platforms and integrated OTN-WDM systems where both capacity and power consumption matter.
Which standards are used with kSIST prES 203 184 V1.1.1:2013?
- ATIS-0600015.2009 - the main companion document for energy-efficiency measurement and reporting; this standard follows its EEER/TEER approach and transport requirements.
- ETSI EN 300 132-2 - provides the -48 V DC power supply interface conditions used for DC-powered equipment tests.
- ATIS-0600015.02.2009 - the transport requirements reference that the document explicitly follows for the transport-equipment methodology and for the TEER comparison model.
What does the kSIST prES 203 184 V1.1.1:2013 document contain?
The document contains the system classification framework, the system description rules, the system configuration rules and the EEER definition. It also includes the laboratory measurement conditions, the fixed and flexible measurement methods, and the handling of CBR and VBR interfaces.
Annex A contains two worked examples: an optical amplifier case and a ROADM WSS-based case. These examples show how the same system description can be implemented in different configurations and how EEER changes between fixed and flexible methods. Annex B provides the bibliography used by the standard.

Foreword
This final draft ETSI Standard (ES) has been produced by ETSI Technical Committee Environmental Engineering (EE),
and is now submitted for the ETSI standards Membership Approval Procedure.
Introduction
The present document defines the metric, methodology and the test conditions to evaluate the Equipment Energy
Efficiency Ratio (EEER) of Transport equipments. Energy efficiency is, in fact, becoming a relevant issue in
Telecommunication area, and increasing efficiency is a commitment in the Transport segment of the network too.
The present document adopts a "two steps" approach, with a system "description" (high level description of the
application, e.g. general characteristics like whole capacity, client and network interfaces with type and number, optical
features like gain, reach, noise figurer, etc.) and a system "configuration" (one of the possible
configuration/implementation of a given system description), as done in ATIS standard on Transport equipment
(see ATIS-0600015.02.2009 [2]).
The EEER is calculated with the same formula of the ATIS standard [2] but with the measurement conditions defined in
the present document. The EEER is evaluated according to the present document for a given fixed or flexible
configuration.

1 Scope
The present document defines the metric, methodology and the test conditions to evaluate the Equipment Energy
Efficiency Ratio (EEER) of Transport equipments. The Transport equipments covered will include all the transmission
equipment connected to the network by means of wired medium (i.e. copper or fiber), typically running at the network
OSI level 1. The present document also covers the equipment running at the network OSI level 2 (e.g. MPLS-TP) that
are not included in the ETSI standard on "Measurement Methods for Energy Efficiency of Router and Switch
Equipment" (the same approach is followed by ATIS standard on Transport equipment,
see ATIS-0600015.02.2009 [2]).
The present document is not applicable at node/network level but only at equipment level.
Examples of typical wired Transport equipments covered by the present document are switches or crosses connects
(SDH, OTN) and add/drop multiplexers (DWDM). The present document covers also simpler systems as
multiplexers/demultiplexers (DWDM), optical amplifiers, transponders.
Transport equipments that exploit radio or wireless interfaces (e.g. free space optics and point to point
wireless/microwave transport) are out of the scope of the present document. It is highlighted that ATIS standard for
transport equipment [2] includes wireless transport equipment.

Foreword
This ETSI Standard (ES) has been produced by ETSI Technical Committee Environmental Engineering (EE).
Introduction
The present document defines the metric, methodology and the test conditions to evaluate the Equipment Energy
Efficiency Ratio (EEER) of Transport equipments. Energy efficiency is, in fact, becoming a relevant issue in
Telecommunication area, and increasing efficiency is a commitment in the Transport segment of the network too.
The present document adopts a "two steps" approach, with a system "description" (high level description of the
application, e.g. general characteristics like whole capacity, client and network interfaces with type and number, optical
features like gain, reach, noise figurer, etc.) and a system "configuration" (one of the possible
configuration/implementation of a given system description), as done in ATIS standard on Transport equipment
(see ATIS-0600015.02.2009 [i.2]).
The EEER is calculated with the same formula of the ATIS standard [i.2] but with the measurement conditions defined
in the present document. The EEER is evaluated according to the present document for a given fixed or flexible
configuration.

1 Scope
The present document defines the metric, methodology and the test conditions to evaluate the Equipment Energy
Efficiency Ratio (EEER) of Transport equipments. The Transport equipments covered will include all the transmission
equipment connected to the network by means of wired medium (i.e. copper or fiber), typically running at the network
OSI level 1. The present document also covers the equipment running at the network OSI level 2 (e.g. MPLS-TP) that
are not included in the ETSI standard on "Measurement Methods for Energy Efficiency of Router and Switch
Equipment" (the same approach is followed by ATIS standard on Transport equipment,
see ATIS-0600015.02.2009 [i.2]).
The present document is not applicable at node/network level but only at equipment level.
Examples of typical wired Transport equipments covered by the present document are switches or crosses connects
(SDH, OTN) and add/drop multiplexers (DWDM). The present document covers also simpler systems as
multiplexers/demultiplexers (DWDM), optical amplifiers, transponders.
Transport equipments that exploit radio or wireless interfaces (e.g. free space optics and point to point
wireless/microwave transport) are out of the scope of the present document. It is highlighted that ATIS standard for
transport equipment [i.2] includes wireless transport equipment.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
Add Drop Multiplexer (ADM): network element that provides access to all, or some subset of the constituent signals
contained within an STM-N signal (in SDH) or in an OTU-k signal (in OTN) the ODUk and ODUflex can be accessed
in a similar way in the OTU. The constituent signals are added to (inserted), and/or dropped from (extracted) the
STM-N or OTU-k in OTN the OTU signal, as it passes through the ADM
card: part of an equipment implementing a given functionality (i.e. data interfaces, switching, control). Line cards with
data interfaces can have more ports
cross connect: apparatus enabling the termination of cable elements and their cross-connection, primarily by means of
patch cords or jumpers
Dense WDM (DWDM): WDM system characterised by an high density of optical signals on a given bandwidth
Digital Cross Connect (DXC): apparatus enabling the termination and the cross connection of signals (including
multiplexing and demultiplexing of signals according to a certain hierarchy) at electrical level
Forward Error Correction (FEC): technique which consists of transmitting the data in an encoded form such that the
redundancy added by the coding allows the decoding to detect and correct errors (e.g. in actual application the FEC is
used to extend the distance of transmission of optical signal)
hot-standby: state in which redundancy cards are not in use (stand-by), but are ready to work immediately when
needed
multi service protocol platform: transport equipment that is able to terminate and switch signals with more than one
protocol transport technology framing
Optical Add Drop Multiplexer (OADM): wavelength selective branching device (used in WDM transmission
systems) having a wavelength "drop" function in which one or more optical signals can be transferred from an input
port to either an output port or drop port(s) depending on the wavelength of the signal and also having a wavelength
"add" function in which optical signals presented to the add port(s) are also transferred to the output port (in OTN these
are the OCh signals)
optical amplifier: devices or subsystems in which optical signals can be amplified by means of the stimulated emission
taking place in a suitable active medium
Optical Cross Connect (OXC): apparatus enabling the termination and the cross connection of signal at optical level
(Optical) regenerator: transmitter-receiver combination device that performs the regeneration of an input optical
signal by means of conversion in the electrical domain and applying an FEC
(Optical) transponder: transmitter-receiver combination with or without pulse shaping and retiming that converts an
optical signal into another optical signal by a conversion into the electrical domain
passive (chromatic) dispersion compensator: passive component used to compensate the chromatic dispersion of an
optical path
port: part of a card in which a cable (typically a fiber) or a transceiver can be plugged to interconnect an equipment to
another compatible one
rack: free-standing or fixed structure for housing electrical and/or electronic and/or optical equipment, usually
organized in a number of slots
Reconfigurable OADM (ROADM): flexibly reconfigurable by means of control or management commands on the
node
slot: part of a rack for housing a card
switch: node that is capable of switching slots or packets/frames from one interface to another
ETSI

transcesiver: combination of transmitter and receiver in a single package that is pluggable on a port of a line card with
compatible characteristics (in terms of rate and framing, for instance 40 GbEthernet)
transport equipment: transport equipment enables information transfer capabilities between originating and
terminating access service facilities
Wavelength Division Multiplexing (WDM): bidirectional multiplexing using different optical wavelength for up and
downstream signals

4.1 Transport System categories
The following three Transport system categories are defined in order to properly provide the System Description.
Category A: terminal and signal conditioning equipment
This category, as regards signal handling by the system, is characterized by two sides: side a and side b (sometimes with
the meaning of Input and Output) as depicted in figure 1. The signals may be uni- or bi- directionally handled on each
of the two sides of the equipment.
The following equipments are examples of the category A:
