METHOD FOR SUPPLYING POWER SOURCE TO MULTIPLEXER IN HOUSE TERMINAL BOX

摘要

A method for supplying power to a multiplexer within a house terminal box is provided to save a space and secure convenience of wiring by using an inverted PoE(Power of Ethernet) method. A method for supplying power to a multiplexer(7) within a house terminal box includes the steps of: transforming AC power supplied from a power outlet terminal(11) into DC power by an internal power supply unit built in a rear side of a wall to which the power outlet terminal(11) is installed; transmitting the DC power originated in the internal power supply unit via a telephone(15) or LAN port(16) installed in each room; and applying the transmitted DC power to the multiplexer(7) in the house terminal box.
