Abstract
Abstract An apparatus adapted for use with a plurality of cable pairs for placing a test condition on a selected cable pair including a cable pair tester and means remote from the cable pair tester for supplying a cable pair command code and a test condition command code. The cable pair tester includes a portion connected to each of the cable pairs with electrical continuity being interrupted between the cable pairs and the cable pair tester. The cable pair tester is adapted to establish electrical continuity between a selected one of the cable pairs and the cable pair tester in response to receiving a cable pair command code uniquely identifying the selected cable pair. The cable pair tester places the test condition on the selected cable pair in response to receiving the test condition command code.
