This is a BusCom right?? Are the phones the 15000 series sets?

I don't remember using a Silent 700 on this system but I probably just don't recall correctly. I thought I used a programming phone to program.....it's been quite a while.

I think I may have thrown out all of my Tie BusCom books, but I'll look anyway. Maybe one of the other Mods will jump in here who has a better memory than I do. ------- Thanks, Skip. Wasn't this programed also by flipping a plastic thing up and moving a small button with a paper clip??
Or was that another TIE system??
