Makes perfect sense now. I had not seen it done that way except for telephone situations (.upstatemike said:Blue blocks (top) are field wiring. White blocks (bottom) are equipment wiring.Mike said:Wow. Telco is right. That isn't all telephone connections is it?
Right half is telephone and left half is automation so telephone switch is on the 4 white blocks to the right while stargate/caddx/RS-485/etc. are on the 4 white blocks on the left.
I use standard telco cross-coonect to patch equipment on the lower blocks to field wire terminated on the upper blocks. Very easy to reconfigure. Have swapped the phone system many times and migrated to Stargate from HomeBrain without disturbing the termination of the core house wiring.
