OPTICAL LINE TERMINAL, AND FRAME TRANSFER METHOD

摘要

A set of identifier information (LLID) of an ONU and a set of transfer command information indicating the transmission system of the output destination of a downlink frame are registered to a table (22) for each user device connected to the ONU or for each address ID of the ONU. When a downlink frame is received from a high order device, a frame transfer processing unit (20) acquires from the table (22) the transfer command information and the LLID corresponding to the address ID of the downlink frame.
