Characteristic of the telephone network is connection-oriented transmission with circuit switching. Communication takes place via explicitly established transmission paths between subscriber interfaces. These dial-up connection paths are set up temporarily and remain in place for the duration of the telephone call. Afterwards, they are removed again.
