Abstract
A transmission speed of a protection (backup) line using 1G-OLT unit and 1G-ONU unit is set to be lower than a transmission speed of a working (primary) line using 10G-OLT unit and 10G-ONU unit. A priority and band of each communication service in ONU are preset individually and separately every LLID for a working (primary) line and a protection (backup) line. When bands are allocated to the protection (backup) line, the band allocation is performed so as to secure a minimum number of bands of each communication service. A monitoring controller refers to a predetermined band information table according to an operation state of the working (primary) line or the protection (backup) line with respect to a downstream signal packet.
