Abstract

A technology for improved power distribution between subscriber lines fed from an RU unit receiving power from an EU unit through a DSL line, the technology comprising: - defining a maximal value of a current Idsl (Idslmax) allowed to be input to the RU unit from the DSL line; - monitoring the input current Idsl of the RU unit and producing a control signal when said input current exceeds the value Idslmax; - dynamically distributing output current of the RU unit between the subscriber lines according to their respective consumption as long as the input current is in the range 0≤ Idsl ≤ Idslmax, while limiting the output current consumption by said subscriber lines upon receiving the control signal that said Idslmax is exceeded.
