  • Data communications system, station device, subscriber device, redundant configuration switch determination method, operation control method, and program therefor
    Publication number: 20050019035
    Abstract: A data communications system switches systems without using an OpS. An OLT determines one of ONTs forming a redundant configuration as a current ONT by performing ranging on the ONTs. When a fault occurs between the coupler and the current ONT, the OLT switches from the current ONT to the standby ONT by activating the standby ONT by performing the ranging on the ONTs again.
