Arrangement for controlling power consumption

A network element of a cable television (CATV) network, said network element comprising

• an input for upstream signal transmission;
• one or more diplex filters connectable to said input, the diplex filters comprising bandpass filters for different upstream and downstream frequency bands;
• a plurality of components arranged to form an upstream signal path, wherein at least one of said components is an upstream amplifier and at least one of said components is an upstream attenuator;
• a control circuit configured to;
• detect a frequency range of an upstream filter of the diplex filter connected between said input and the upstream signal path;
• determine an attenuation value of the upstream attenuator;
• determine a control signal for adjusting bias current of the upstream amplifier, wherein the control signal is based on at least the frequency range of the upstream filter of the diplex filter and the attenuation value and a difference between an actual input level and a nominal input level of an upstream receiver of the upstream amplifier;
• and
• adjust the bias current of the upstream amplifier based on the control signal.
