Three radios are available in the aircraft for TTY
transmission and reception: UHF-2, HF-1, and HF-2.
The TSEC/KW-7 security unit provides encryption and
decryption for all teletype data. The teletype information

SYSTEM COMPONENTS
The following is a brief description
components of the teletype system.
Keyboard Transmitter TT-568/AGC-6
of the major
The keyboard transmitter is shown in figure 1-19.
This unit controls the TTY system. In addition to a
standard keyboard, there are special function keys
provided.
Teleprinter TT-567
This unit (fig. 1-20) is a high-speed printer. It
contains the necessary hardware and logic circuitry to
process baudot inputs and produce hard-copy outputs.
TTY Signal Data Converter
This unit (fig. 1-21) provides an interface between
the TTY and the radios. It converts teletype language
(baudot code) into audio tones, which can be transmitted
