ABSTRACT:
Each of the cellular telephones is adapted to receive a paging signal and to transmit a voice channel signal on a voice channel frequency in response to the paging signal. The alert system includes a receiver tuned to receive the voice channel frequency. A trigger circuit is connected to the output of the receiver to be activated by the receiver when the receiver receives a voice channel signal on the voice channel frequency. An alert is produced by either an audio signal generator, a vibratory generator or a radio mute, and each of the latter is connected to the ouput of the trigger. Thus, an alert is provided on receipt of an incoming telephone call.
