Abstract

The method involves using one of the base stations (FP1) as a main station and all other stations (FP2-FPN) as dependent sub-stations. Alternatively a digital signal processor (DSP) can be used as a main station and all the base stations as sub-stations. A signalling channel of the main station and/or the digital signal processor is exclusively used as a synchronisation channel. The synchronisation channel is used for the synchronisation between the DECT controller unit (DCU) and the fixed stations as well as for the synchronisation between the fixed stations, themselves. The main station and/or the digital signal processor preferably transmits a synchronised system-multiframe sequence on the synchronisation channel. The sequence is then retransmitted by the DECT controller unit to all further sub-stations as well as to the main station.
