I'm experiencing the same issue with port/extension 110 having its buttons light up for no reason on the 8-port expansion card on a new DX-120 system. I already unassigned the features and swapped out phones. It might be a coincidence its port 110 as your problem is, but I'm suspecting a dirty phone jack (an upside down mounted wall jack that's been there at least 15 years) or a bad cable that is causing noise (I've seen a Progressive Electronics toner cause a DX-80 phone's buttons to light up). I replaced the wall jack and used the spare paris...will see what happens for a week.
