An arrangement for line-conducted digital telecommunication between a line termination (1) of a telecommunication network and subscribers (Tln) connected to this network is specified in which at least one subscriber (Tln) equipped with terminals is connected to a network termination (2) via an electrical line (L3), in which the network termination (2) is connected to the line termination (1) via a line (L2) containing metallic conductors and in which the line termination is equipped with a voltage source (SV) for supplying its own power and for supplying power to the network termination (2) and to the terminals of the subscribers (Tln). To increase the operational reliability, two separate power supply units (SVE1, SVE2) are arranged in the network termination (2), one of which is used for feeding the active components of the network termination (2) and the other one of which is used for feeding the terminals of the subscribers (Tln). The two power supply units (SVE1, SVE2) are connected to the voltage source (SV) of the line termination (1) via separate conductors.
