Abstract: A cross-connect panel for a high density digital signal cross-connect (DSX) bay is disclosed. The panel includes a plurality of cross-connect termination points grouped in an array which includes a plurality of horizontal spaced-apart rows. A plurality of troughs are defined between opposing rows. The rows are divided into two spaced-apart set. A second trough extends vertically through the height of the panel in vertical alignment with gaps defined between the spaced-apart sets. The vertical trough is offset from the plane of the horizontal troughs.

Abstract: An apparatus is disclosed for providing access to plurality of telecommunication lines. The apparatus includes a frame which carries a plurality of normally closed contacts. The telecommunication lines are terminated on the normally closed contacts. A plurality of modules are provided to be releasably attached to the frame with electrical circuit elements on the modules engaging the normally closed contacts to open the contacts and create a new signal path through the module upon insertion of the module into the frame.

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.
