Abstract

Switching equipment in provided for performing a switching process of a fixed length cell consisting of data and a cell header. A line interface provided in the switching equipment accommodates a plurality of lines and, at the same time, processes the data from each line on a cell unit. The line interface includes individual units and a common unit. The individual units are individually connected to the plurality of lines accommodated therein and individually process the cells. The common unit is connected to the individual units and, at the same time, effects batch-processing of the cells processed by the individual units.
