A method and system for transmitting data between two communication devices via a packet-oriented communication network, wherein the communication devices are, in each case, connected to the packet-oriented communication network via a conversion device. Time-slot-oriented signaling and user information allocated to a connection between the communication devices are separated at the transmitter end by the conversion devices. The signaling information is then transmitted transparently via a first link via the packet-oriented communication network. The user information is converted into a data format supported by the packet-oriented communication network for transmission via the packet-oriented communication network and is then transmitted via a second connection. Finally, the user information is converted back at the receiver end and joined together with the signaling information.

Method and system for transmitting data between two communication devices via a packet-oriented communication network

ISDN basic interface S.sub.o of an ISDN communication system that can be connected to an S.sub.o interface of an ISDN communication terminal equipment or of an ISDN terminal of a public communication network (ISDN-PSTN) is provided. For automatic recognition and commissioning of such an ISDN terminal, this is first initialized as one of the possible connection modes and the processes of layer 1 and layer 2 are activated in interaction with the administration and maintenance and dependability processes. When it occurs from the message traffic of the individual components that a commissioning is not possible, then the appertaining S.sub.o terminal is initiated with the next connection mode and the commissioning is restarted. The controller previously made the corresponding, new configuring data available. After a successful commissioning, the S.sub.o terminal is ultimately configured in the corresponding connection mode and the messages required for this purpose are communicated to the switching-oriented and administration and maintenance components. After unsuccessful commissioning attempts (line not plugged), the commissioning of all connection modes is again cyclically implemented after a predetermined time.
