ETSI ES 205 200-2-4规定了固定资产绩效方面的全球关键绩效指标（KPI） 宽带电缆接入网（CAN）。KPI以传输的数据量表示，数据量与 家庭用户终端和网络前端之间的配电网消耗的能量。这个 KPI考虑了欧洲有线网络主要部署的HFC接入网络拓扑 接线员。本文件阐述了ETSI ES 205 200-1[1]中规定的目标1至4，以鼓励减少能源消耗；提高工作效率；扩大能源再利用；可再生能源的应用。全球KPI的定义符合ETSI ES 205 200-1[1]中与以下方面有关的要求:基础设施可扩展性；基础设施演变；术语的公式和定义； 测量点和程序。本文件参考并介绍了全球KPI“能源绩效”，符合 与上述目标相关的ETSI ES 205 200-1[1]。随着服务趋向于独家使用数字传输技术，本文件仅考虑 与数字服务支持相关的网络KPI。连接到客户场所网络接口单元（NIU）的所有家用设备的贡献，例如 电缆调制解调器（CM）、网关（GW）和机顶盒（STB）可以满足能源消耗和任何其他客户的需求 连接到家庭网络的房屋设备不在本文件的范围内。本文件 仅考虑接入网络的组件，以定义和测量能耗 绩效指标。

ETSI ES 205 200-2-4 specifies Global Key Performance Indicators (KPIs) in terms of the performance of the fixed broadband Cable Access Network (CAN). The KPIs are expressed in terms of transmitted data volume in relation to the energy consumed by the distribution network between the in-home subscriber termination and network headend. The KPIs are taking into account the predominantly deployed HFC access network topologies by European cable network operators.The present document addresses the objectives 1 to 4 as set out in ETSI ES 205 200-1 [1] to encourage:reduction in energy consumption;improvements in task efficiency;extension of energy re-use;application of renewable energy.The definition of the Global KPIs is in accordance with requirements of ETSI ES 205 200-1 [1] in relation to:infrastructure scalability;infrastructure evolution;formulae and definition of terms;measurement points and procedures.The present document refers to and introduces the Global KPI 'Energy Performance' in accordance with requirements of ETSI ES 205 200-1 [1] in relation to the above objectives.With services trending towards exclusive use of digital transmission technologies, the present document considers only the network KPIs relevant for the support of digital services.The contribution of all in-home equipment connecting to the customer premises network interface unit (NIU) such as the cable modem (CM), gateway (GW) and settop box (STB) to energy consumption as well as any other customer premises equipment connected to the in-home network are out of scope of the present document. The present document only considers components of the access network for the purpose of defining and measuring energy consumption key performance indicators.
