Title: Good reference; poor introduction
Product review: Don't waste your money on this tome if you're a beginner like myself. However, if you are a professional, this would be a great reference to have on your desk. A more detailed book on telephone switches probably doesn't exist.For beginners, the author really provided way too much detail. His writing style is very bland. In order to understand the dense material, you have to follow the words very carefully, and then you probably would doze off. Like the other reviewer, I find the density of material counterproductive and impenetrable.
