A digital radio link suitable for transmitting digital voice or data signals includes an input circuit (61) for ATM or frame relay cells/frames attached to an ATM or Frame Relay network, a forward error correction encoder and decoder (67) with indication of uncorrectable blocks due to burst errors, a payload processing module (64) for modifying bits in the frames or cells so that frames/cells extracted from a forward error correction block containing bit errors will not be misinserted by the network.
