Abstract
In a PON system in which communication is performed at a plurality of types of transmission rate (L, M, and H) in an upstream direction from a plurality of terminals connected to a station apparatus through optical fibers, within a discovery period for allowing an unregistered terminal to be recognized by station apparatus, the terminal makes a discovery response at one type of transmission rate (L). With this configuration, station apparatus can wait for a discovery response with a receive function being allowed to support transmission rate (L).
Claims4
A device for a passive optical network system in which communication is performed at a plurality of types of transmission rate in an upstream direction from a plurality of terminals connected to a station apparatus through optical fibers, the device comprising:
- a receiver for receiving a discovery gate message transmitted by the station apparatus;
- and
- a transmitter for transmitting a discovery response, wherein:
- within a discovery period for allowing an unregistered terminal to be recognized by the station apparatus, the transmitter is configured to make the discovery response at a limited predetermined transmission rate among the plurality of types of transmission rate, and
- the predetermined transmission rate is specified by the station apparatus.
