Abstract:
An optical line terminal (OLT) (20), which is connected to a higher-level network, is provided with: a passive optical network (PON) control unit (110) that acquires information indicating the state of an optical network unit (ONU) on the basis of a PON protocol; an ONU state management unit (111) that acquires the information indicating the state of the ONU from the PON control unit (110), and retains said information as state information; an Ethernet Operations, Administration, and Maintenance (EOAM) processing unit (113) that communicates with the higher-level network on the basis of EOAM; and a protocol conversion unit (112) that sets, for the EOAM processing unit (113), an alternate point, which responds in an equivalent manner to the case in which a monitoring point has been set in EOAM in the ONU on the basis of the state information.
