ATM communication terminal devices (KE ) of a communication network that is designed according to ATM can be inventively allocated to a ring network structure, whereby a ring network address (EA,GA) is respectively assigned to these ATM communication terminal devices (KE ), and the ring network access and the ring network communication are controlled in a ring-network-specific manner. On the basis of the imaging, into the virtual channel identification (VCI) of ATM cells, of a ring network address (EA,GA) identifying one or more ATM communication terminal devices (KE ), an emulated ring network structure (LAN emulation) is realized easily.

When an external terminal is signed on to a communications system, a voice link is set up between the external terminal and a teleworking subscriber line module of the communications system. Control information which is transferred in the form of DTMF signals from the external terminal via the voice link is converted at the teleworking subscriber line module into signaling information such as is usually available within the scope of a signaling protocol between internal terminals and the communications system.

When an external terminal is signed on to a communications system, a short message service link is set up between the external terminal and a teleworking computer connected to the communications system. Control information which is transferred from the external terminal via the short message service link is converted by the teleworking computer into signaling information that is usually available within the scope of a signaling protocol between internal terminals and the communications system. The converted short message control information is then transferred on to a control unit of the communications system.

In a transmission of voice data, the stream of voice data is first decomposed into phonemes. For each phoneme a code symbol which is assigned to that specific phoneme in a selectable voice-specific and/or speaker-specific phoneme catalog is transmitted to a voice synthesizer at the transmission destination. The amount of data which has to be transmitted is generally greatly reduced. The decomposition of the stream of voice data into phonemes is carried out by a neural network which is trained to detect the phonemes stored in the selected voice-specific and/or speaker-specific phoneme catalog. The voice synthesizer reconverts the stream of received code symbols into a sequence of phonemes and outputs it.

In response to a connection setup initiated by a time-division-multiplex-oriented component, an ATM-communications-network-specific destination information item is derived from a specified signaling information item, and an ATM switched connection is automatically set up in the ATM communications network. After a transparent transfer of signaling and useful information via the switched connection that has been set up, the ATM switched connection in question is released. This provides more efficient use of the ATM communications network.
