A majority vote circuit determines when the majority of a group of signaling channels is properly conveying a common message in conjunction with a status signal individual to each channel. Respective status and message signals from each channel are scanned in pairs and in sequence. The number of valid message and status signals are accumulated in separate counters. A comparison circuit triggered by the completion of a scanning sequence matches counter outputs stage by stage to determine whether or not the count level in the message signal counter exceeds by one-half the count level in the status signal counter as an indication that a majority of a variable majority of the working channels conveys the same message signal.
