Abstract: A method and apparatus for receiving square root cosine pulse uplink transmissions from a transmitting Time Division Multiple Access radiotelephone to activate a switch. Upon initial activation of the switch the apparatus will operate in a dual mode method, that method being from either a TDMA or Analog transmission signal. The apparatus utilizes receivers tuned to decode transmitted time slot frequencies of a TDMA radiotelephone and an analog signal rectifier receiver for analog radiotelephone transmissions to activate a means of audible, visual, mechanical and other notification methods.
