1. A method governing the operation of alert annunciation in response to decoded pager addresses from received pager signals, said method comprising the steps of:

  • (a) decoding any one of a plurality of predetermined pager addresses from received pager signals;

    (b) generating a first digital word having a code uniquely corresponding to one of said decoded pager addresses of step (a);

    (c) decoding any one of a plurality of address functions associated with said decoded pager address from received pager signals;

    (d) generating a second digital word having a code uniquely corresponding to one of said decoded address functions of step (c);

    (e) selecting a subset of combined codes of said first and second digital words from a set of all coded first and second digital words by assigning a pattern code selected from a limited plurality of pattern codes to each member of said subset;

    (f) generating an alert signal in response to the generated first digital word of step (b) and the generated second digital word of step (d) having a combined code which is a member of said subset with an annunciation pattern corresponding to the assigned pattern code thereof; and

    (g) inhibiting alert signal generation in response to the generated first digital word of step (b) and the generated second digital word of step (d) having a combined code which is not a member of said subset.
