  • System for interfacing an alarm reporting device with a cellular radio transceiver
    Patent number: 5131019
    Abstract: A system for interfacing an alarm reporting unit with a cellular radio transceiver so that the data which is produced by the alarm reporting unit is effectively matched to the radio transceiver, irrespective of its initial format, includes circuitry for matching the format of the alarm reporting unit to that of the cellular radio transceiver, and circuitry for matching the format of the cellular radio transceiver to that of the alarm reporting unit, to permit interactive communications which assure the reliable transmission of data while allowing suitable acknowledgement signals to be returned to the alarm reporting unit to regulate the effective transmission of data within the system, and isolation circuitry to effectively separate the alarm reporting unit from the cellular radio transceiver so that the alarm reporting unit can communicate with a monitoring facility via the cellular radio transceiver, as well as the wired telephone network.
