telephony
     
         Communication, often two-way, of spoken
        information, by means of electrical signals carried by wires
        or radio waves.  The term was used to indicate transmission of
        the voice, as distinguished from telegraphy (done in {Morse
        code} and usually called "{continuous wave}" or CW
        transmission), radio teletypewriter (RTTY) transmission (also
        called FSK for "{Frequency Shift Keying}", the modulation
        scheme used by such machines), and later, facimile.
