In an overload control method for a spread spectrum communication system, when the number of mobile stations communicating with a base station is equal to or more than a predetermined number, the ratio of increase instructions to reverse link transmission power control bits transmitted to the mobile stations from the base station is measured. A Dispersion-Managing Raman Amplifier combines Raman amplification with dispersion compensation by selecting the length and dispersion of the gain fiber to balance the dispersion of the link. This arrangement is useful, as in many cases, the customer’s security system is hidden within a closet, or else placed within the home or business at a significant distance from their Internet connection and router. Additional processing may be performed to detect user gestures or other user input relevant to portable device control. The tangs of the first metal sheet space the first and second metal sheets from one another and the tangs of the second metal sheet substantially fixedly engage the first and second metal sheets with respect to one another.
