Its unlikely that it was special-built for the Space Shuttle. Obviously this is speculation, but it most likely was already special-designed for a military application and just re-used in the shuttle. All of those strategic nuclear bombers that used to fly on standby 24/7 needed communications, too.
You don't need to speculate. As I explained in the thread, the Shuttle teleprinter was based on the military AN/UGC-74 teleprinter but had many modifications including new three circuit boards for the FSK decoding.
