RELIABLE TRANSMISSION OF SIGNALS IN A MULTI-CHANNEL SYSTEM IS ACHIEVED BY TRANSFERRING SIGNAL INPUTS FROM A DEFECTIVELY OPERATING OR INOPERATIVE TRANSMITTER TO ANOTHER TRANSMITTER WHICH CONTINUES TO TRANSMIT OTHER CHANNELS. AT LEAST TWO TRANSMITTERS (50,51) ARE OPERATED NORMALLY, EACH TRANSMITTING ITS OWN BLOCK OF CHANNELS. A SENSOR (70) DETECTS WHEN THE OUTPUT OF ONE TRANSMITTER IS IMPROPER OR NON-EXISTENT, AND CAUSES A CHANGE-OVER SWITCH TO OPERATE. OPERATION OF THE SWITCH ADDS THE BLOCK OF CHANNELS WHICH HAD COME FROM THE ONE TRANSMITTER TO THE OTHER (OR ONE OR MORE) OF THE TRANSMITTERS (50,51), SO THAT THE REMAINING TRANSMITTER OR TRANSMITTERS NOW PROVIDE ALL THE CHANNELS.FIGURE 1
