What systems do you mean?

Let's just say that there are ancient communications systems still in use because they still work acceptably well and would cost big $$$ to upgrade. The cost isn't mainly associated with hardware and software, but rather in changing complex processes & procedures, retraining personnel, testing reliability and interfacing with other ancient systems, etc. "Red Tape" stuff. It ain't broke enough yet to fix it, unfortunately.
