The computer I have always used to program my CTG-2 crashed, so I had to replace it with a new one. Is there a way to capture the data from the CTG-2 and save it to the new computer?

I am wiring a C-2000, C-2000A or C-2000B into a trunk port/FXO Port on my phone system and I get a constant clicking from the controller when I access that trunk port/FXO port. What does this mean?
