A full detailing of my system would require too much space and time. All cables are in use with the exception of a third RG in MBR. The way the system is configured, loss of any cable, interface, router, etc, does not result in the loss of any function. Entire system from security, thermostat settings, TIVO, telephones, to starting coffeepot is controlled from computer, including laptop carried in vehicle. Many services and components have been added over the past 11 years and I probably will add more as additional technology becomes available. At the present time I am checking out whole house satellite telephone systems.
BTW, Don has never had to bid on a project. All are negotiated. When he built for me it was cost plus fixed fee.
