Abstract
A multi-function electronic messaging system for transmitting messages over a first communications link having a remote unit for generating forward error corrected signals representing various types of electronic messages, for generating acoustical tones corresponding to the error corrected signals is provided. The acoustical tones are coupled to the send-only first communications link and transferred to a computer. The computer sends an acknowledgement signal back to the user of the remote unit over the first communications link and decodes and error checks the signals. The computer also reformats the various messages and resends them out over various communication links depending on the ultimate destination of the message. The computer may also send messages to the remote unit over a receive-only second communications link. A multi-level method of error detecting and correcting data is also disclosed.
