A method and a transmitter (100) and a receiver (102) for transmitting messages (114) in a digital telecommunications system. The information (104) to be sent is encoded in an information encoder (106) of the transmitter (100) into frames that are transmitted via a transmission path (108) to the receiver (102). A good state and a bad state have been defined for the frames, and a bit pattern corresponding to each message (114) has been defined. The messages(114) are encoded with a message encoder (116) of the transmitter (100) and transmitted to the receiver (102). The messages (114) are transmitted together with the information (104) via a common transmission path (108), inserting the bit pattern corresponding to the message (114) in the frame, forming the frame corresponding to the time of transmitting the message (114) as bad, and in short sequences, preferably only one frame at a time. The messages thus transmitted can be received together with the information (104) via a common transmission path (108) simply by detecting a bad frame that additionally contains a bit pattern deviating from the bit pattern corresponding to the message in a few bits at most. The bad frames corresponding to the time of message transmission are replaced with a preceding good frame.
