PCT No. PCT/FI94/00372 Sec. 371 Date Apr. 19, 1996 Sec. 102(e) Date Apr. 19, 1996 PCT Filed Aug. 24, 1994 PCT Pub. No. WO95/06363 PCT Pub. Date Mar. 2, 1995A method and a system for performing redundancy control of the baseband primary channel interfaces of a plurality of mutually substantially identical receivers in a digital transmission device, such as a radio link, including: monitoring the quality of a signal 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; and performing redundancy control of the baseband primary channel interfaces of the receivers on the basis of the failure situation comparison so that the signal of higher quality of the output signals of the receivers is transmitted towards the primary channel.
