ABSTRACT:
A method of mapping a virtual container multiplexed with a pointer indicating a first bit position in a transmission frame onto an asynchronous transfer mode cell and transmitting the virtual container thus converted. The method includes the steps of deriving a first bit position of the virtual container in the transmission frame from the value of the pointer of the virtual container, mapping the virtual container onto information fields of cells, deriving a first bit position of the virtual container within a cell information field of the asynchronous transfer mode cell from the first bit position information in the frame, and writing the first bit position information within the cell information field and information contained in the pointer into a field which has a fixed phase relationship with respect to a cell header and transmitting the cells.
