General

The present document defines the power consumption metrics, the methodology and the test conditions to measure the 
power consumption of broadband fixed telecommunication networks equipment. The present document does not cover 
all possible configuration of equipment but only homogenous configurations. 
The types of broadband access technologies covered by the present document are the ones widely deployed at the date 
of publication. Currently, the present document considers DSLAM DSL, MSAN, PON OLT and Point to Point OLT 
equipment. Other access technologies may be included in further versions of the present document. 
The present document also considers measurement methodology for VDSL2 equipment with vectoring functionality. 
In addition to the full power state, power-saving states as defined in DSL standards [i.1] and [i.2] are also covered. 
The present document focuses on Network Equipment. The end-user equipment is handled in other documents, see 
ETSI EN 301 575 [i.6] for CPE [i.6] and ETSI EN 303 423 [i.9] for network standby. 

The present document is based upon Energy Efficiency Benchmark for Data storage products. 
The present document specifies: 
1) an active state metric, test conditions and product family configuration for the assessment of energy efficiency 
of DSE using reliable, accurate and reproducible measurement methods; 
2) an idle state metric and the calculation of the idle state power; 
3) a measurement method of the active state power; 
4) a measurement method of the idle state power; 
5) the measurement and calculation of the maximum power; 
6) the measurement and calculation of the operating condition class, the ASHRAE validation, using reliable, 
accurate and reproducible measurement methods, which take into account the recognized state of the art; 
7) requirements for equipment to perform the measurements and analysis; 
8) documentation and reporting requirements; 
9) evaluation methodology for energy saving level from the perspective of supported energy saving features. 
The present document addresses DSE. 
The present document is applicable at the energy efficiency of: 
• online storage; 
• nearline storage. 
The present document defines metric for the assessment of energy efficiency of DSE and related testing methodology 
considering data storage equipment HW and system.

This standard specifies the requirements for the equipment and activities associated with the safe 
storage and transfer of LPG under pressure at ambient temperatures in fixed and in skid mounted 
pressure vessels with a water capacity greater than 150 litres.
