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