Abstract
In a network that includes one or a plurality of optical line terminals, a plurality of branches, and an optical routing unit, the optical network unit registration method includes a first process in which the optical line terminals transmit a discovery gate to the optical network units, and a second process in which, in response to the discovery gate, an unregistered optical network unit transmits a register request to a separate optical line terminal from the terminal that transmitted the discovery gate. A discovery window is provided in the optical line terminal that receives the register request. This optical line terminal receives the register request in the discovery window.
