Mark, I agree with Eric, you are aways away from cutting and hacking on traces until we can identify exactly which backplane board you are working with.
Most of the time that I have seen the TRN prefix, it usually has been tied to the PURC series of radios. Are all of your backplane boards that you have, this same model number? On the backplane board what are the cards slots labeled as? Knowing this information may help identify what the original station service type was.
