Energy costs continue to increase, a trend that will continue in the future, while broadband penetration is introducing

new active equipment to the network architecture. In this context, and to reflect other environmental aspects of

sustainability, it is vital that the main telecommunication actors implement effective general engineering of fixed and

mobile broadband networks and sites provisioning, managing or using those networks (i.e. operator sites, operator data

centres and customer data centres) in order to respond to critical issues of energy consumption while proposing essential

solutions to true broadband deployment. To guide this process, it is essential that metrics are defined, termed Global

Key Performance Indicators (KPI ), that enable energy usage to be managed more effectively.

• Annex A discusses the roles of different types of Key Performance Indicators i.e. Technical, Objective and

Global in relation to the overall energy management concepts of the present document.

The present document specifies the requirements for a Global KPI for energy management (KPI ) and their

underpinning Objective KPIs addressing the following objectives for the fixed access networks (FANs) of broadband

The requirements are mapped to the general requirements of ETSI ES 205 200-1 [1].

Energy management of fixed access networks comprises a number of independent layers. The present document

addresses performance of infrastructures that supports the normal function of hosted ICT equipment within the fixed

access network (e.g. power distribution, environmental control, security and safety). The present document does not

address other layers such as performance of ICT equipment itself, performance of usage of available processing power,

and layers related to final service delivered (e.g. processing power required per itemized outcome) or overlay layers

The environmental impact and management of different energy sources are outside the scope of the present document.

KPI may be tailored for specific needs by changing weighting of renewable energies. Calculations should be based on

The Global KPI alone is not designed for comparison of fixed networks. It does not define a fixed network as good or

bad unless combined with other parameters considered relevant for a comparison, such as local climatic conditions,
