THE DEVICE AND METHOD FOR LIFE-LINE SUPPORTS IN FAILURE OF PON FOR FIBER OPTIC ACCESS SYSTEM AND IT'S CONTROLLING SCHEME

摘要

An object of the present invention is to provide an optical subscriber terminal (ONT: Optical Network Terminal) that can provide a continuous lifeline service in the event of a failure in a passive optical network (PON) and a control method thereof.;According to the present invention, the WDM filter unit for filtering by wavelength-multiplexing the input optical signal; An Ethernet unit for communicating with the Internet; A gigabit Ethernet processor configured to receive the signal filtered by the WDM filter unit and perform Ethernet processing at high speed through the Ethernet unit; Plain Old Telephone Service (POTS) unit for performing lifeline communication; A route switching unit for converting a telephone route via the POTS unit into a copper line; And a power supply unit for supplying power, wherein the power supply unit controls the path switching unit to control the path of the lifeline if the signal using the power to send the alive message is not detected during the value set by driving the timer. An optical subscriber connection device is provided which bypasses and monitors for equipment failure.;Optical Subscriber Interface, Ethernet, POTS, Lifeline
