When my wife and I buy our next home, I am going to take the time to do basically as you have: to build in the data networks, switching modules, home alarm panel, and radio/tv blocks all in one central distribution area. As it stands right now, I don't have the connectivity to support all my activities from my office. I can work and place calls but no data and no coax connections to the HAM antennas, nor can I determine at a glance what zone has been opened if the alarm trips.
You have A LOT of twisted pair on that block. I was under the impression that your home office is in the photos? Either you've lots of phones or lots of data ports throughout the house. Your fire panel is rather commercial looking too. Bravo -- can't be too overbuilt on either front IMO.
All in all, very, very impressive squirrel25. Thank you for taking the time to share.
