摘要: The present invention provides an independent supervised communications network which interfaces with existing cellular telecommunications by utilizing locally unused frequencies to report information from a premise central monitoring facility. This utilizes input device associated the for providing one or more status messages transceiver module. module may be modified telephone is operable in of three modes; supervision, event and wait. phone modifications are primarily software changes provide logic routine scanning selecting available forward control channel based on comparison preselected criteria measured characteristics determining reverse corresponding selected channel. transmits message processor over predetermined duration, either periodically if supervision continuously message. processor, placed at site proximate site, receives decodes transmitted
