A distributed DSLAM, which comprises a head end subsystem located within a switching facility and a remote subsystem located outside of the switching facility. In accordance with principles of the invention, a balanced net radiometer can be constructed where each thermal absorber is formed from two separate pieces joined together to form a single thermal mass. The method further comprises analyzing a responsiveness andor compliance characteristics of the assisted individual, and providing the assisted individual with voice messages in a form most acceptable and effective for the assisted individual on the basis of the analyzed responsiveness andor the analyzed compliance characteristics. The target component is typically a slow response component, such as a magnet. Said slip ring is designed such that it can only be applied or removed to the lock casing from the back of the casing and is properly aligned with said encasement through a setscrew that will break if sufficient torque is applied.
