Abstract
A network element of a cable television (CATV) network, said network element comprising one or more amplifier units for amplifying downstream signal transmission for digital output into one or more output channels; means for detecting output power of all active digital output channels; means for providing a predetermined correlation between the detected output power of said active digital output channels and a corresponding minimum bias current for said one or more amplifier units; and means for adjusting the bias current of said one or more amplifier units on the basis of the predetermined correlation.
