Abstract
The pager receiver including a conventional address decoder, an alert envelope waveform generator, and an alert function mapper is disclosed. The pager is individually and uniquely characterized by programming the alert function mapper to govern the generation of assigned alert annunciation patterns by the waveform generator in response to selected decoded pager addresses and associated functions thereof, and to inhibit alert generation by the waveform generator in response to non-selected decoded pager addresses and associated functions thereof. In one embodiment, the alert signal waveform generator is enabled to respond to the alert function mapper only when the pager address is decoded by the decoder.
