Method for supplying power to network users in a data communications network employs network users, a central network data distributor and communications devices for data transmission between network users and data distributors.

摘要

A communications device (LKG) like an Ethernet switch, a hub, a media converter, an alarm sensor/actuator or a radio modem feeds current remotely to a network user (NTE) connected to it. A network data distributor (NDV) also feeds current remotely to the LKG as does another LKG. A separate remote current/communications device (FKG) feeds current remotely to the LKG and to a passive remote feeder bus.
