Programmable paging encoder
First Claim
1. A paging encoder for the transmitter means of a telephone paging system of the type incorporating means for transmitting coded data to portable receiver/decoder units, comprising:
- a microcomputer programmed to contain a look-up table including tone and space data for plurality of paging formats and routines for converting input data to a tone and space code for a selected one of said paging formats;
input means for providing input data to said microcomputer;
selection means for altering the function of said microcomputer to cause it to provide output tone and space codes in a selected one of said paging formats; and
output means for coupling tone and space codes produced by said microcomputer as encoded data to said transmitter means.

Abstract
A paging encoder including a microcomputer having a look-up table containing code formats for the more popular paging systems and an energy conservation means whereby the microcomputer is maintained in an off state except when called upon to perform an encoding function by a keyboard input means. This is accomplished by a microcomputer programmed to contain a lookup table including tone and space data for a plurality of paging formats and routines for converting input data, such as a telephone number, to a tone and space code for a selected one of said paging formats as programmed by a selection means which alters the function of the microcomputer to cause it to provide the desired output tone and space codes in accordance with the selected paging format.
