With the advent of paging receivers capable of receiving alpha messages the ability to enter alpha messages from a simple telephone key pad is desirable. Several techniques have been described in the past. One tech- nique includes requiring acaller to carry acard with numbers representing a limited vocabulary of words. Another technique requires a caller to carry a portable electronic device capable of electronically communicating alpha characters over a phone line. Still another technique does not require the caller to carry extra cards or elec- tronic devices, but require the caller to push multiple telephone keys to enter one letter. Entire messages can be entered this way but the message must be entered one letter at a time, with an average of two key strokes per letter. It is an object of this invention to provide a means for entering alpha messages from a telephone key pad without requiring extracards orelectronic devices while substantially reducing the numberof telephone key presses.
