Access, Terminals, Transmission and Multiplexing (ATTM); Energy management; Global KPIs; Operational infrastructures; Part 2: Specific requirements; Sub-part 2: Fixed broadband access networks

Scope

The present document specifies the requirements for a Global KPI for energy management (KPIEM) and their
underpinning Objective KPIs addressing the following objectives for the fixed access networks (FANs) of broadband
deployment:
• energy consumption;
• task effectiveness;
• renewable energy.
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
(e.g. energy consumption required per itemized outcome).
The environmental impact and management of different energy sources are outside the scope of the present document.
KPIEM may be tailored for specific needs by changing weighting of renewable energies. Calculations should be based on
a significant sample of network elements.
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,
availability requirements or purpose of fixed networks.
