ABSTRACT:
An apparatus and a method for determining faults in a telephone line. The apparatus has an enclosure housing a switch. The switch is for electrically communicating with a ring wire of a telephone line, with a tip wire of the telephone line, and with an electrical ground. The switch selectively permits electrical communication between any two of the ring wire, the tip wire, and the ground. The apparatus improves testing of the telephone line by helping identify an electrically open condition in the telephone line.
