<p>In digital communication systems, such as FDMA/TDMA digital cellular mobile radio systems (1) in which a number of radio base stations transceivers (BS1,BS2,BS3) communicate with a number of mobile radio stations (MS1,MS2,MS3 ), frequency hopping techniques are used for combating fading inter alia. When implementing such frequency hopping techniques, data bursts have to be routed between transceivers (RFU1,RFU2, ...,RFUn) and transceiver controllers (RCC1,RCC2, ...,RCCn) in the radio base stations transceivers (BS1,BS2,BS3) according to a frequency hopping algorithm. In order to get a more fault tolerant system inter alia, point-to-multipoint structures (RXL1,RXL2, ...,RXLn;TXL1,TXL2, ...,TXLn) between transceiver receiver sections (RX1,RX2, . ..,RXn) and transceiver controllers (RCRX1,RCRX2, ..., RCRXn), and between transceiver controllers (RCTX1,RCTX2, ...,RCTXn) and transceiver transmitter sections (TX1,TX2, ...,TXn) are proposed. In case of failure of a transceiver or a transceiver controller most of the current traffic can still be handled. Then, the system can simply be reconfigured to become fully operative again, though with a slightly reduced capacity. <IMAGE></p> |
