ABSTRACT:
A station interface and protector apparatus for use on a telephone line pair includes a protector device having terminals connected from each line to a round terminal, via a gas discharged tube and/or a protective air gap and includes an insulated cover which covers the protector device and is provided with a telephone receptacle (jack) to which the incoming telephone line pair is connected. A cable having a plurality of wires therein is terminated on one end with a cooperating telephone line plug disposed within the receptacle with the other end of the cable wires being connected to a plurality of terminals provided in the cover which is additionally adapted to receive the subscribers telephone line pairs. By removing the cable plug from the jack provided in the cover the incoming telephone line may be isolated from the subscribers wiring, thus inserting a known operating telephone into the housing receptacle and operating the telephone will immediately determine if the problem exists in the incoming telephone lines or the subscriber's wiring.
