Abstract:
An optical line terminal is provided which includes an upward band allocating unit configured to send an upward bandwidth allocation map to an optical network unit and to determine a sleep mode of the optical network unit according to whether a response message corresponding to the upward bandwidth allocation map is received; and an alarm unit configured to determine an upward bandwidth allocation map transfer operation as a normal operation according to an operation of the sleep mode.
