Every voter I've ever seen requires COR/COS in some way. The Motorola
and GE voters are normally configured to use what is called 'status
tone', with the link path being phone lines. The status tone is active
continuosly. When the remote rx opens squelch, it mutes the status tone
encoder, which indicates to the voter on the other end that a signal is
present.
Without some sort of indication of COR/COS, there is no way for the
voter to know whether what it is seeing is valid signal or not, and it
will likely vote to something it shouldn't.
