Abstract
A digital mobile communication network and a switching system for a digital mobile communication network are provided. A traffic frame may include speech signals converted into a parameter group by a speech encoder and, as a whole, may be inserted into a payload part of a data packet. The data packet can be sent to a destination via a transmission network. At the destination, the traffic frame is separated from the payload of the received data packet and the traffic frame is passed to a transcoder unit for restoring the original speech signal. The transmission network can be an asynchronous transfer mode network and the data packet can be an asynchronous transfer mode cell.
