<p>Multiple format secure voice apparatus for communication handsets includes a core unit (12) with a speaker (15), a microphone (16), a keypad (17), and a display (18). The core unit also includes an audio circuit (20) coupled to the speaker and the microphone, an encryption/decryption element (25) coupled to the audio circuit, a coder/decoder element (27) coupled to the audio circuit and the encryption/decryption element, and a control element (30) coupled to the keypad, the display, the audio circuit, the encryption/decryption element, and the coder/decoder element. A standard interface coupling (35) is connected to an audio I/O terminal (21), a data I/O terminal (28) of the coder/decoder element, and a control I/O terminal (32) of the control element. A mating standard interface coupling (40) mates with the standard interface coupling of the core unit and is coupled to the mating standard interface coupling.</p> |
