Title: Expensive door-stop
Review: This is quite possibly the most badly written book I have ever read. All the concepts and details are in there - but, just like Prego, there's no particular order or discernable logic to it. At least with Prego, you can get something to eat out of the deal..Russell's book introduces ideas and concepts before they're defined, repeats definitions, and generally just meanders around. And, for the nit-picky, the grammar is sloppy as well.Anybody wishing to learn about SS7 would be better off searching the internet and reading the SS7 tutorials found there. I'm using my copy as a $69.00 door-stop.
