Phone Circuit.

a 3-way switch turns phone service on/off from 2 locations

an LED indicates when the phone is on/off at the 2 locations

a switch toggles phone service between the land line (local) and internet
phone (long distance)

N.C. contacts permit use of the phone when power outages disable the relay
coil.

Right, but why pay for it? Because that's before Apple and PC computers started going wireless and/or high speed internet.

Now you can do all that from a desktop, tablet or your wireless phone service (like with "Skype" and "MajicJack" and through most chat rooms.
