Abstract
An MC-ONU is an ONU installed at a subscriber's home. The MC-ONU includes: a receiving unit which receives signals transmitted from an OLT at a telecommunications carrier site which has not established a link; a determining unit which determines the OLT, which has not established a link, to be a remote-end device in point-to-point communication on the condition that the signal received for a predetermined period of time is idle signal only; and a transmitting unit which starts transmitting signals to the OLT from the subscriber's home on the condition that it has been determined by the determining unit that the OLT is the remote-end device in point-to-point communication.
