Abstract: A distributed communication system consisting of at least one communication device, preferably a private communication installation, and at least one central data processing device which are connected to one another via a network, preferably an IP-oriented network, wherein the central data processing device executes at least one communication application, and a central database for storing overlapping data, which are accessed by at least one communication device and/or at least one communication application, is arranged in the communication system.

Abstract: A method and apparatus for improving the transmission quality in a packet-oriented data transmission network, wherein time-critical data is transmitted over a packet-oriented data transmission network having a number of communications equipment units which are networked to one another.

Abstract: In order to design a cellular cordless telecommunications system which makes it possible to implement a large number of performance features, for example synchronization, roaming, handover, internal links, hold, check-back, transfer etc. in the cellular cordless telecommunications system without any additional wire link between the cordless base stations in the cellular cordless telecommunications system, the cordless base stations are connected to an S0 bus (i.e., a basic access line for a multi-device configured system).
