A communication apparatus is provided which comprises: extraction means for extracting a virtual path identifier and a virtual channel identifier stored in a first header of first cells output from a terminal; preparation means which, based on the extracted virtual path identifier and virtual channel identifier, refers to a conversion table to prepare a second header containing a corresponding identifier; cell generation means for generating second cells containing the prepared second header and the user information of the first cells; multiplexing/generation means for multiplexing the generated second cells so as to have a fixed length, thereby generating third cells; and send means for sending the generated third cells to other communication apparatus through a virtual channel. By virtue of this construction, the usage charge of communication lines, such as ATM lines, can be reduced.
