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 cell routing method and apparatus in an ATM processing apparatus. The ATM processing apparatus has two or more routing tables associated with address filters of an ATM switch to store routing information for indicating the destination of cell output, and two or more conversion tables associated with VPI conversion circuits for replacing VPI (Virtual Path Identifier) or VCI conversion circuits for replacing VCI (Virtual Channel Identifier) to store information for indicating the VPI or VCI obtained after conversion. In an input interface circuit, selection information indicating which routing table and conversion table out of the above described two or more routing tables and two or more conversion tables should be selected is written into an occupied area within a cell. In a switch circuit, the selection information is read and one routing table is selected out of the above described two or more routing tables on the basis of the selection information thus read, and cell routing is thus performed based on information in the selected routing table. Further, in an output interface circuit, selection information contained in the cell is read and one conversion table is selected out of the above described two or more conversion tables on the basis of the selection information thus read, and VPI conversion or VCI conversion is thus executed based on information in the selected conversion table.

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.
