One day you pick up the receiver for your land line phone and there is no dial tone. The line cord is plugged into the phone and the wall jack. You call the phone company to report your outage. The company representative asks if you have their insurance on the lines within your house. You respond that you do not. They tell you it could be very expensive if they come out and the problem is with the lines inside your house. Would it not be nice to know for certain the problem is with the phone company lines and not with the lines in your house?
There is a box on the side of your house, usually gray in color, where the phone lines come into your home. The one in the photo was painted over the last time the house was painted. For some reason, this house has two such boxes. The one on the left happens to be the active box for the phone service. The box may be mounted low on the house and may be a different shape.
Step 1: Open the Terminal Box
This box opens with a 3/8 inch socket. Some open with a screwdriver.
