ABSTRACT:
A switching equipment accommodates lines and includes a line interface for processing data from the line on the unit of cell. The line interface has a basic processing unit and an additional processing unit. The basic processing unit performs a basic process on the cell. The additional processing unit separated from the basic processing unit but disconnectably connected to the basic processing unit executes an additional process on the cell. The additional processing unit includes a plurality of processing blocks for effecting a plurality of additional processes on the cells. Each processing block is individually disconnectably connected to the basic processing unit. The basic processing unit includes a selecting portion for selecting, when one or more processing blocks within the additional processing unit are connected, the connected processing blocks and performing the additional process on the cell.
