  • 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
    Patent number: 6715087
    Abstract: A method for sending a remote power feed to a terminal in a local area network. A repeater of the local area network produces a detection signal in a line to which a remote terminal is connected, and the signal has an energy level that will not damage the terminal. The presence of a remote terminal adapted to receive a remote power feed via the repeater is detected by detecting the presence of a predetermined impedance in the terminal, and power is supplied to the terminal via the repeater in response to detection of the presence of the terminal.

    Patent number: RE44325
    Abstract: A method for sending a remote power feed to a terminal in a local area network. A repeater of the local area network produces a detection test signal in a line to which a remote terminal is connected, and the signal has an energy level that will not damage the terminal. The presence of a remote terminal adapted to receive a remote power feed via the repeater is detected by detecting the presence of a predetermined impedance in the terminal, and power is supplied to the terminal via the repeater in response to detection of the presence of the terminal.
