Introduction The present document defines the energy consumption limits and measurement m
15、ethods for fixed broadband (DSL) telecommunication network equipment. ETSI ETSI TS 102 533 V1.1.1 (2008-06) 5 1 Scope The present document defines the power consumption limits, the methodology and the test conditions to measure the power consumption of broadband fixed telecommunication networks equi
16、pment. The power consumption limits are based on the European Code of Conduct for Broadband Equipment i.1. The types of broadband access technologies covered by the present document are the ones widely deployed at the date of publication. Other access technologies may be included in further versions
17、 of the present document. In addition to the full power state, power-saving states asdefined in DSL standards i.2 and i.3 are also covered. Currently, the present document only considers DSLAM DSL equipment.Future versions will also include MSAN equipment. Other access technologies (e.g. WiMAX, PLC,
18、 optical) are not yet considered because they are still in an early stage of development/deployment The present document focuses on Network Equipment.The end-user equipment is not handled in the present document.For limits for end-user Equipment please refer to the current revision of the Code of Co
19、nduct for Broadband Equipment i.1. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

30、ions apply: active line: line in operational mode and carrying traffic as specified for that mode of operation (ADSL2plus or VDSL2) broadband terminal equipment: equipment of broadband technology that is connected beyond the Network Termination Point of a telecommunication network broadband telecomm
31、unication network equipment: equipment of broadband technology that is part of a telecommunication network full-power state: state in which the maximal allowed data transmission is possible.The maximum is defined by the physical properties of the line and the settings of the operator (e.g. L0 for AD
32、SL2/2plus) low-power state: allows 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 transmission during a certain time is lower than the limit. If more than the limited data has to be transmitte
33、d 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 for ADSL2/2plus). stand-by state: has the largest power reduction capability and there is no transmission of
34、 data possible NOTE: From this state a direct state change to the full-transmission state is possible, if data has to be transmitted from either side (e.g. L3 for ADSL2/2plus). power consumption: power used by a device to achieve an intended application performance ETSI ETSI TS 102 533 V1.1.1 (2008-

39、 DSLAM) is defined as: PBBline = PBBeq / Nsubscrib-lineswhere: PBBeqis the power consumption (in W) of a fully equipped broadband equipment (DSLAM), measured at the electric power input interface, placed at the premises of the operator or the equipment supplier, which connects multiple broadband sub
40、scribers to a backbone. PBBlineis the power consumption per line in W of the broadband equipment for which the limits are defined in the present document. Nsuscrib-linesis the maximum number of subscriber lines served by the broadband equipment (DSLAM) under test. PBBeqis measured in determined envi
41、ronmental conditions defined in clause 5.1.7. ETSI ETSI TS 102 533 V1.1.1 (2008-06) 8 4.2. Definition of Normalized Power Consumption per line for Broadband Network Equipment In addition to the power PBBlinethat is defined for one equipment, an indication of global network power performance might be
42、 given. The “Normalized Power Consumption“ (NPC) is an indicator of the amount of power required to transport 1 Mbps of data over a 1 kilometre distance NPC = 1000 x PBBline/(bitrate x line length) NPC is expressed in mW/Mbps/km. where: Bitrate is in Mbps and line length is in km. For DSLAM, the NPC
43、 shall be based on the bitrate and reach at full-power state as defined in the measurement method (see clause 5.1.5).The definition of the NPC can be found in TR 102 530 i.5. This NPC enables comparison of different technologies (such as ADSL2(plus) and VDSL2) regarding the efficiency of transportin
44、g information (in terms of power). It shall be calculated at relevant data points for each technology. These data points are derived from the typical or targeted working conditions of these technologies and are given in the clause on measurement methods (clause 5.1.5). For instance, ADSL2plus might
45、be deployed with a loop length of around 3 km with a data rate of 5 Mbps, or with shorter loops of 1 km with a data rate of 20 Mbps. NOTE: NPC can be used for comparing different products with the same technology, different products in different technologies or different generations of the same tech
46、nologies. Using the NPC to compare the different working states (e.g. L0 with L2 or L3) is not recommended as the intention of some of these working states is to save energy at times of no or low-rate transmission - i.e. when there is no need to transmit high data rates. NPC is not the only paramete
47、r to compare power consumption at service level. For comparing power consumption of certain service types (e.g. VoIP vs. PSTN) a different parameter might be more relevant. 4.2.1 Power consumption taking into account the low-power states The low-power states are intended to reduce the power consumpt
48、ion during periods of no or minimal traffic needs (e.g. low data-rate applications or control signalling only). When these low-power states are used, the achievable power consumption reduction can be estimated by using profiles based on user traffic assumptions, as illustrated in annex A. NOTE 1: Us
49、age of power-saving states. A number of power-saving states are defined in the DSL standards (L2, L3, ITU-T Recommendation G.992.3 i.2, ITU-T Recommendation G.992.5 i.3).These power-saving states shall be implemented, both in the Network equipment subject of the present document and the CPE/end-user equipment deployed at the premises of the user of the broadband line; this will enable 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 a
