Abstract:
1. A node system, comprising: a high-speed interface unit which mounts a first high-speed interface transforming a first high-speed optical signal to a high-speed electric signal and a second high-speed interface transferring a serial high-speed electric signal to a second high-speed optical signal; a low-speed interface unit which mounts a first low-speed interface transforming a first low-speed optical signal to a low-speed electric signal and a second low-speed interface transferring a serial low-speed electric signal to a second low-speed optical signal; a time division switch which exchanges a parallel high-speed electric signal and a parallel low-speed electric signal; a switch unit which mounts a high-speed multiplex circuit multiplexing the parallel high-speed electric signal to the serial high-speed electric signal, a low-speed multiplex circuit multiplexing the parallel low-speed electric signal to the serial low-speed electric signal, a high-speed demultiplex circuit demultiplexing the high-speed electric signal to the parallel high-speed electric signal, and a low-speed demultiplex circuit demultiplexing the low-speed electric signal to the parallel low-speed electric signal; and a controller which controls transmissions between said first high-speed interface and said time division switch, between said first low-speed interface and said time division switch, between said time division switch and said second high-speed interface, and between said time division switch and said second low-speed interface; wherein said high-speed interface unit, said low-speed interface unit, and said switch unit can mount on a system lack and are composed by building block method in necessary numbers, depending upon demanding function and scale.
