摘要： An optical transmission system accomplishes optical transmission over a long distance by combining a multiplexing line terminal with optical amplifiers, linear repeaters, and regenerators with optical amplifiers combined together. The system also accomplishes the optical transmission over a short distance by directly connecting the linear terminals therebetween, with an electric-to-optic converter replaced by an electric-to-optic converter having a semiconductor amplifier, with an optic-toelectric converter by an optic-to-electric converter having an avalanche photodiode as light receiver, and with no use of any optical booster amplifier and optical preamplifier in multiplexing line terminal. With these, the optical transmission system can be easily constructed depending on the transmission distance required.

摘要： An ATM switch has a plurality of concentration space-division switches each constituted with an S-stage connection of switch modules. Each of the switch modules includes M buffers and a selector for selecting an arbitrary one of outputs from the M buffers. Each stage includes switch modules of which the number is obtained by multiplying by at most M a number of switch modules disposed in a stage succeeding thereto. The S stages include a final stage constituted with a switch module.

摘要： A method of switching a route path of a ring network having a plurality of route paths for signal transmission, in which a transmission station on a transmission side transmits information of a same content to said plurality of route paths, a transmission station on a reception side selects one of the plurality of route paths, and a failure on the selected route path is automatically retrieved. The method includes the steps of: monitoring whether a signal received on each route path is normal or not; loading failure information as a path status identifier in a predetermined field of the signal received on each route path, the failure information indicating whether the monitoring step has detected a failure; and selecting one of the plurality of route paths in accordance with the failure information and predetermined logic.
