Method of providing a remote power feed to a terminal in a local area network, and corresponding remote power feed unit, concentrator, repeator, and terminal

A terminal adapted to be connected to a local area network and to receive a remote power feed via a line, wherein the terminal includes at least one predetermined impedance connected to at least two conductors of the line and which identifies terminals adapted to receive a remote power feed, wherein the predetermined impedance is a very much higher capacitance than that of terminations routinely connected to the ends of the lines in terminals that are not adapted to receive a remote power feed but are adapted to be connected to the local area network.

A repeater adapted to receive a remote power feed and adapted to be included in a line between a network equipment unit including a remote power feed unit and another network equipment unit in a local area network,

• the repeater including a power supply unit powered by a remote power feed and whose input is connected in parallel with the power supply input of the other network equipment unit to the conductors of the line that provide the remote power feed, and
• the power supply unit having an input impedance whose modulus is very much higher than the modulus of the input impedance of the power supply unit which is characteristic of equipment units adapted to receive a remote power feed likely to be connected downstream of that repeater.
