Abstract: A collective packet generator forms collective Internet Protocol (IP) data packets, each of which contains several IP data packets of different communication data streams, for encrypted transmission of each of the communication data streams as a sequence of IP data packets. A particular collective IP data packet is encrypted by an encryption module for encrypting IP data packets.

Abstract: The circuit-oriented components of at least one function area of a communication system are combined on at least one area module. For a configuration of the communication system, a combination--determined by the central controller and stored in this controller--of a circuit technology identification and at least one function identification is transmitted to the respective area module and is stored there in the sense of a specification of the circuit-oriented and procedural functions of the area module. At least one program module allocated to the combination of a circuit technology identification and at least one function identification is transmitted to the respective area module, using the central controller, and is stored in this controller.

Abstract: A system is provided for connection of terminal equipment units of wireless telephone systems. A communication system is connected by trunk lines to a plurality of base stations. Each base station has a radio module for communicating with a plurality of terminal equipment units. The communication system has a plurality of base station line modules, with each base station line module having a switching unit for effecting a switching of the communication terminal equipment units wirelessly connected to the base station. Furthermore, in each base station line module, the switching unit is connected to a transmission unit which in turn connects to the trunk lines, said trunk lines connecting to the base stations. The transmission unit in each base station line module and its respective trunk lines communicate digitized voice and signalling information according to a burst-operation transmission method.

Abstract: The base stations (BS) in a multicellular, wireless telephone system are connected via trunk lines (VL) to a communication system (KS), particularly to a telephone private branch exchange. The base stations (BS) are arranged at such a distance from one another that synchronization information (si) wirelessly transmitted from one base station (BS) can be at least partially received in a neighboring base station (BS). Both the initial, wireless synchronization as well as the synchronization during operation are controlled by the communication system such that respectively one base station (BS) is synchronized to the synchronization information (si) transmitted from a neighboring base station (BS). Compared to a synchronization of the base stations (BS) via trunk lines (VL), these deviations due to running times and different processing speeds in the synchronization unit realized in circuit-oriented terms are avoided in the wireless synchronization.
