按适用供应商列出的关键绩效指标 在作战情况下。本文件的范围仅涉及多服务接入节点 MSAN，配置用于光纤到户（FTTH）和数字用户线（DSL）使用。考虑到MSAN中嵌入的能耗表的预期实现，允许实时 关于能源消耗的知识，第4条提出了应由网络管理的运营KPI 管理系统（NMS）。本文件提出了工程KPI，以评估和模拟现场能耗。

ETSI GS OEU 002 proposes Key Performance Indicators (KPI) applicable by vendors in laboratories or by operators in operational situations. The scope of the present document is exclusively dealing with the Multi-Service Access Node MSAN, configured for both Fiber to the Home (FTTH) and Digital subscriber line (DSL) usages.Considering the foreseen implementation of energy consumption meters embedded in the MSAN allowing real time knowledge of energy consumption, clause 4 proposes the operational KPIs which should be managed by the Network Management System (NMS).The present document proposes engineering KPIs to evaluate and to model on-field energy consumption.
