"It seems to me likely that anyone reading a book on ISDN probably knows there's a class of information out there that's neither inborn or intuitive. It's often difficult, and you have to dig it out. But you take on that challenge because the information is powerful and valuable. It opens doors to both practical advantage and a better quality of life. And it's fun as well. This book is full of such information."
