ABSTRACT:
A method and system for testing the continuity of a transmission line in a non-addressable network. A method and system in a communications service environment are provided, the environment including an addressable network and a non-addressable network, for testing transmission line continuity in the non-addressable network. In an embodiment, a signal generator connected to a first transmission line in the addressable network generates a signal on the first transmission line. The first transmission line is connected to a second transmission line in the non-addressable network by a bridge. The bridge transfers the signal from the first transmission line to the second transmission line. The system also includes a signal receiver connected to the second transmission line for receiving the signal over the second transmission line when the second transmission line is continuous. The receipt of the signal over the second transmission line at the signal receiver indicates that the second transmission line is continuous.
