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.
