ABSTRACT:
With the deployment of ISDN within a building, a resistor box is usually required, at each distribution frame, between the first and second set of cross-connect connectors in order to maintain a balanced loop. In the present invention, a quick connect terminating resistor for use with cross-connect type of connectors is disclosed. It is used for eliminating the use of the resistor box. The quick connect terminating resistor is comprised of a body having a connecting end, conductor portions on said body at said connecting end adapted to mate with a pair of terminals of said cross-connect type connector and resistor means connected to said conductor portions for providing a terminating resistance across said pair of terminals of said cross-connect type connector.
