摘要： The station-side terminal apparatus for the optical access network includes: the station-side terminal apparatus; the subscriber-side terminal apparatuses connected to the station-side terminal apparatus via the optical transmission line; the terminal devices to which mutually different wavelengths are assigned; and the communication failure detecting unit. Each of the terminal devices includes the uplink communication state monitoring unit configured to monitor a state of uplink communication for each registered subscriber-side terminal apparatus, on the basis of the input uplink signal, and the downlink communication failure information extracting unit configured to extract information of a state of downlink communication, which is transmitted from the registered subscriber-side terminal apparatus. The communication failure detecting unit detects a failure of the uplink communication and a failure of the downlink communication, on the basis of the state of the uplink communication and the state of the downlink communication.

摘要： A central-office termination apparatus includes plural termination devices and a termination device distributor. Each termination device includes a buffer, a subscriber-terminal terminator distributor and a scheduler. The buffer has a through queue and one or more switching queues. The subscriber-terminal terminator distributor transfers a packet meant for one subscriber-terminal terminator under switching to the switching queue, and transfers another packet meant for another subscriber-terminal terminator not under switching to the through queue. The scheduler reads out packets from the switching and through queues. The termination device distributor transfers a received packet to a termination device having the subscriber-terminal terminator registered for which that packet is meant.
