16、defines the energy consumption limits and measurement methods for fixed broadband telecommunication network equipment. ETSI ETSI ES 203 215 V1.2.1 (2011-10) 51 Scope The present document defines the power consumption limits, the methodology and the test conditions to measure the power consumption of

17、 broadband fixed telecommunication networks equipment. Some proposal power consumption limits are provided as informative data. The document does not cover all possible configuration of equipment but only homogenous configuration. The types of broadband access technologies covered by the present doc

18、ument are the ones widely deployed at the date of publication. Currently, the present document considers DSLAM DSL, MSAN, GPON OLT, Point to Point OLT equipment. Other access technologies may be included in further versions of the present document. In addition to the full power state, power-saving s

19、tates as defined in DSL standards i.1 and i.2 are also covered. The present document focuses on Network Equipment. The end-user equipment will be handled in another document. 2 References References are either specific (identified by date of publication and/or edition number or version number) or no

30、ons 3.1 Definitions For the purposes of the present document, the following terms and definitions apply: active line: line in operational mode and carrying traffic as specified for that mode of operation (ADSL2plus or VDSL2) broadband telecommunication network equipment: equipment of broadband techn

31、ology that is part of a telecommunication network broadband terminal equipment: equipment of broadband technology that is connected beyond the Network Termination Point of a telecommunication network full-power state: state in which the maximal allowed data transmission is possible NOTE: The maximum

32、 is defined by the physical properties of the line and the settings of the operator (e.g. L0 for ADSL2/2plus). low-power state: state in which a limited power reduction capability and a limited data transmission is allowed NOTE: It is entered automatically from the full power state after the data tr

33、ansmission during a certain time is lower than the limit. If more than the limited data has to be transmitted from either side a state change to the full power state is entered automatically. The low power state may comprise multiple sub-states with history dependant state transition rules (e.g. L2

34、for ADSL2/2plus). power consumption: power used by a device to achieve an intended application performance stand-by state: state in which the largest power reduction capability and no transmission of data is possible NOTE: From this state a direct state change to the full-transmission state is possi

35、ble, if data has to be transmitted from either side (e.g. L3 for ADSL2/2plus). telecommunication network: network operated under a license granted by a national telecommunications authority, which provides telecommunications between Network Termination Points (NTPs) (i.e. excluding terminal equipmen

40、 = PBBeq / NportsWhere: PBBeqis the power consumption (in W) of a fully equipped broadband network equipment, measured at the electric power input interface, placed at the premises of the operator or the equipment supplier, which connects multiple broadband subscribers to a backbone. PBBeqis measure

41、d in determined environmental conditions defined in clause 5.1.1. PBBportis the power consumption per port in W of the broadband network equipment for which the limits are defined in the present document. Nportsis the maximum number of subscriber lines access ports served by the broadband network eq

42、uipment under test. ETSI ETSI ES 203 215 V1.2.1 (2011-10) 84.2 Power consumption taking into account the low-power states The low-power states are intended to reduce the power consumption during periods of no or minimal traffic needs (e.g. low data-rate applications or control signalling only). When

43、 these low-power states are used, the achievable power consumption reduction can be estimated by using profiles based on user traffic assumptions, some example of user hourly traffic as illustrated in annex B. NOTE 1: Example of power-saving states usage. A number of power-saving states are defined

44、in the DSL standards (L2, L3, ITU-T Recommendations G.992.3 i.1 and G.992.5 i.2). These power-saving states are implemented, both in the Network equipment (i.e. the subject of the present document) and the CPE/end-user equipment deployed at the premises of the user of the broadband line; this will e

45、nable the operator to use these to further limit the power consumption of the equipment. Further study is required to optimize the way in which the low-power states are controlled. In particular, to determine the levels of interference that might arise due to the fluctuating crosstalk caused by freq

46、uent multi-state power transitions. It is important to notice that it is only possible for GPON to use stand-by state if all ONU are in stand-by state and not individually as possible for Point-to-Point transmission. NOTE 2: Additional power saving solutions. A number of additional power saving solu

47、tions are available. Some of these are listed below. However the list is not complete and both the developers and users of broadband network equipment are encouraged to investigate and introduce new power saving solutions: square4 Politeness algorithms. square4 Dynamic Spectrum Management. square4 B

48、oards optimized for remote applications (reduced line power). square4 Dynamic power saving for unused components such as line card, chipset, port, etc. 5 Measurement methods This clause describes the methods to measure the power consumption of broadband network equipment and also gives the condition
