Abstract
A switching system transfers information cells from time positions on incoming TDM channels to selected time positions on a particular outgoing TDM channel. Each information cell contains an address which controls the switching and data which is the transmitted message. A first time buffer delays the incoming information cell from the time position which in occupies on the incoming channel to a time position which is appropriate for the switching. After a switching, a second time buffer delays the outgoing signal unit the time position designated by the address. The alignments of the time positions on the outgoing channels are such that there is no conflict if a plurality of switching systems simultaneously feed information cells to the same outgoing channel.
