Abstract: The present invention provides a method for managing a terminal device in a PON network. When a layer 3 network between an OLT and an ONU is disconnected, a layer 2 channel is established between the OLT and the ONU by extending an OAM protocol, and the ONU is managed by using the layer 2 channel. In this way, maintenance personnel do not need to go to a site to perform commissioning, and therefore, maintenance costs can be reduced.
