Query: Disappointing

I bought this book several years ago when I was setting up a home network with a wireless router and a few PC's on wired connections. The book goes way overboard in extolling all of the things you can do with networking. However, when it comes down to practical detail--it is sorely lacking. For instance, I needed to know which lines were active on a CAT-8 cable (I needed to 'share' one cable between an ethernet link and a tip/ring phone). Was this bit of practical information to be found? No. However a quick search on the internet and I got the schematic for the standard CAT-8 connection and my PC and POTS phone were peacefully coexisting. Sadly, I returned this book to the shelf where it has been collecting dust ever since.
