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 equipment.
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 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, 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 Conduct for Broadband
Equipment [i.1].

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following definitions 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 telecommunication 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 ADSL2/2plus)
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 transmitted 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 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

telecommunication network: network operated under a license granted by a national telecommunications authority,
which provides telecommunications between Network Termination Points (NTPs) (i.e. excluding terminal equipment
beyond the NTPs)

4 Definition of power consumption
4.1 Definition of power consumption per line of Broadband
Equipment
The power consumption of broadband telecommunication network equipment (i.e. in the case of DSL access
technology, the DSLAM) is defined as:
P = P / N
BBline BBeq subscrib-lines
where:
P is the power consumption (in W) of a fully equipped broadband equipment (DSLAM), measured at the electric
BBeq
power input interface, placed at the premises of the operator or the equipment supplier, which connects multiple
broadband subscribers to a backbone.
P is the power consumption per line in W of the broadband equipment for which the limits are defined in the
BBline
present document.
N is the maximum number of subscriber lines served by the broadband equipment (DSLAM) under test.
suscrib-lines
P is measured in determined environmental conditions defined in clause 5.1.7.
