Abstract: There is provided a voice and digit compatible fully automatic radio paging system comprising a radio page central station and a plurality of pagers with voice and digit compatibility. The central station automatically captures a digit and voice information from a telephone network, automatically generates a radio page information based on a predetermined coding protocol, sets up a page information database. The page information is coded by a coder and is then sent by a transmitter in combination of voice and digit. The pager receives and stores the voice and digit information. The information can be repeatedly displayed. The system allows a digital pager to operate together with a pager having voice and digit compatibility in same network, whereby solved the problem that a paging system is not able to transfer an analog voice signal in the past.
