The invention relates to a method and a system for performing redundancy control of the baseband primary channel interfaces (L1; L2) of mutually substantially identical receivers (A, B; C, D) in a digital transmission device, such as a radio link or the like. The method according to the invention comprises the steps of: monitoring the quality of a signal (RA, RB; RC, RD) received from the transmission line; monitoring a possible failure indication or alarm signal concerning the transmission direction at the far end; performing a failure situation comparison between the mutually redundant receivers (A, B and C, D); performing redundancy control of the baseband primary channel interfaces of the receivers (A, B; C, D) on the basis of the failure situation comparison so that the signal of higher quality of the output signals (LRA or LRB; LRC or LRD) of the receivers (A, B; C, D) will be transmitted towards the primary channel (L1; L2). |
