Scott,
I've often wanted to write that book. The closest you'll get to it is in the Committee T1 standards that describe different interfaces between the network and the "Customer Installation". I never convinced them to have a rationale statement for each requirement. Some of the "rationales" are disappearing as technology changes, but the people who knew the rationales aren't around any longer to tell us. The contributions that led to the requirements and gave the rationales may still be in someboies archives (not mine). (I believe that similar conditions are at play in IEC 60950). Sorry I can't be more helpful than that. Ciao, Vic
