Abstract
An arbitrary signal is converted to IP packets, which are routed by an IP packet routing part to Optical path signal conversion parts. Optical path signals from the Optical path signal conversion parts are provided directly to an optical path route switching part of an IP packet transmission equipment. By the optical path route switching part, optical path signals, obtained by wavelength-demultiplexing of OTM signals from optical backbone transmission lines by OTM/optical path signal conversion parts, and optical path signals from the Optical path signal conversion parts are cross-connected to output routes according to their destinations.
