In digital radio communication systems such as FDMA/TDMA digital cellular mobile radio systems, in which a number of radio base stations communicate with a number of mobile radio stations, frequency hopping is used to combat fading. That requires that data bursts be routed between the transceivers (RFU1, RFU2, . . . , RFUn) and the transceiver controllers (RCC1, RCC2, . . . , RCCn) in a radio base station according to a frequency hopping algorithm. Such routing has heretofore been done by transporting the data bursts over a bus which serves as a common distribution medium between the transceivers and the transceiver controllers. In order to achieve a more fault tolerant system, instead of a bus the invention uses as a common distribution medium point-to-multipoint links (RXL1, RXL2, . . . , RXLn; TXL1, TXL2, . . . , TXLn) between the receiver section of each transceiver and the receiver sections of all of the transceiver controllers, and between the transmitter section of each transceiver controller and the transmitter sections of all of the transceivers. In case of failure of a particular transceiver or transceiver controller, most of the existing traffic can still be handled. Also, the system can readily be reconfigured to become fully operative again, though with slightly reduced capacity.
