Abstract
A remotely programmable radiotelephone and a remote programming unit. The radiotelephone (10) includes a receiver front end and demodulator (23), receiver signal processing circuits (30), a dual-tone, multiple-frequency converter (31), a controller (50), and a memory (51). The converter (31) converts DTMF tones into digital signals. The controller (50) monitors the output of the converter (31). If the output corresponds to a valid command then the controller (50) executes the command. Certain commands must be preceded by the user entering an access code using a control keypad (56) and by the reception of DTMF tones corresponding to a password or security code stored in the memory (51). Some commands cause telephone numbers to be stored in the memory (51) for later recall by the user. Other commands cause a number to be stored and an outgoing call to be automatically initiated. The remote programming capability allows a user's secretary to cause the radiotelephone (10) to place a call to a party specified by the user, and allows a dealer to reprogram operating parameters and features of the radiotelephone (10) without the user having to come to the dealer's place of business. The remote programming unit provides for the manual or computer-assisted programming of the radiotelephone.
