Systems and methods are provided for decoding data using hard decisions and erasures. The identity of subscriber A is transmitted to the mobile services switching center of subscriber B via signaling that is unrelated to the speech connection. To improve the quality of the overall control system, the present invention utilizes a universal occupancy adapter for converting any motion detector for a security system, into a component of the lightingbuilding controller. A vibration transfer member transfers the vibration from the first compressing unit to the second compressing unit. By doing so, interference with the transmission waves of nearby radio base stations can be avoided.
