A conditioner unit is wired in parallel with a pair gain test controller used to test a digital loop carrier telephone network. The conditioner unit senses a signal intended to request test results from the pair gain test controller and provides a response signal which indicates that the pair gain test controller performed a successful test, even though the pair gain test controller was not activated. This allows testing of the network without use of a bypass pair or the need to interface the digital loop carrier network with the pair gain test controller.
