The Optelator II is a well known product in the AM/ FM broadcast industry.  Optelator II will work with  Sine Equipment, but it does take a little programming effort  for it to work.

An Engineer, Mr. Brian Hill,  from Back Yard Broadcasting in Pennsylvania discovered that it was not the Optelator being the problem, rather a reprogramming adjustment is requirement for ring sensitivity for the Sine Equipment. 

            Example: RFC1 B unit: 

            Access memory address 1014

            Enter value (10) then hit pound (#)

This changes the Factory Default of  (0) = 1.79 volts sensitivity to 4.66 volts sensitivity.

Brian’s Fear was, could that be a problem because any transit surges higher the 1.79 will get through?  The answer is quit simple.  It is impossible, because the optelator link is fiber optics,  that means there is no possibility  of any  transits at all  that can even get anything above 4.66 volts.
