Abstract: In a telecommunication network, having at least first and second original equipment electrically connected by at least a first existing conductor, a method is disclosed for adding intermediate equipment to the network. The intermediate equipment is connected to the first original equipment by at least a first replacement conductor and the intermediate equipment is connected to the second original equipment by at least a second replacement conductor. A method for adding uses a temporary circuit having at least first and second test conductors. The method includes the steps of electrically connecting first and second replacement conductors to the additional equipment. The first temporary conductor is electrically connected to the original conductor at a first point of connection. The second temporary conductor is electrically connected to the original conductor at a second point of connection. The second point of connection is disposed between the second original equipment and the first point of connection.
