General Information
The Motorola STU 111/SECTEL combines clear/secure voice and
secure data
communication functions into one easy-to-use
telephone. This manual shows
how to install, use, and troubleshoot
the telephone. It also discusses the necessary security measures
to
communicate voice and data in secure mode.
This manual is divided into nine key chapters. Each chapter is
separated by tabs, with primary headings printed in color. Every
chapter stands alone, so you may skip from one chapter to
another to find the information you need.
This chapter provides general
information on the STU 111/SECTEL,
overviews the equipment's purpose and features, and lists the
relevant technical specifications.
Chapter 2, Controls and Indicators, discusses the location and use
of the keypad, memory dial keys, message display and Crypto
Ignition Keys (CIKs). For a quick overview of the STU 111/SECTEL,
turn to Chapter 2.
Chapter 3, Installation, explains
how to unpack the system, where
to locate it, and how to perform the necessary setup and
programming steps to prepare the system for operation. After
performing the steps outlined in Chapter 3, the STU 111/SECTEL
will operate as a normal telephone, but requires a crypto fill to be
able
to transmit or receive secure voice or data.
Chapter 4, Security Considerations and Procedures, provides the
crypto fill procedure and discusses checking crypto status,
zeroizing the CIKs, and zeroizing the STU
111/SECTEL unit itself.
Chapter 4 also provides an overview
of the operation of the

STU 111/SECTEL as a secure device. It explains classification levels
of the unit and its display.
If your system is already set up, filled with an operational key, and
you wish to make a call, turn to Chapter 5, Voice Communication,
or Chapter 6, Data Communication (Secure Mode Only). These
two chapters show how to send or receive voice calls in either
clear or secure modes, how to set protocols for data
communication, and how to send or receive a data file in the
secure mode only.
Chapter 7 covers equipment Care and Cleaning. Chapter 8,
Troubleshooting, explains how to isolate faults with the system
and provides a list of error display messages; and Chapter 9
discusses the
Models and Accessories available for the STU Ill/
SECTEL system.
Most of the instructions in this manual apply to both the STU Ill/
SECTEL 1000 and STU 111/SECTEL 2000. Any differences that
exist are individually addressed.
Ninety percent of our commercial and military communications
are transmitted (at least in part) via microwave or satellite

repeaters. Both of these methods are susceptible to interception
by rival businesses or governments. The STU 111/SECTEL
(Figure 1-1) provides the high level encryption necessary to protect
our nation's military and industrial secrets.
• Small Size. No larger than a standard office telephone, the STU
111/SECTEL fits easily on any desk.
• No noisy blowers or fans. An efficient external power converter
assures
that the STU 111/SECTEL will be a welcome addition to
any office environment.
• Retention of emergency communications. If power is
interrupted for any reason, the STU 111/SECTEL will function as
a plain old telephone (POT) to provide reliable communications
in an emergency situation.
• Field upgradeability. Motorola is continually developing
enhancements to ensure that the STU 111/SECTEL maintains its
state-of-the-art position among secure communications systems.
• Ease of programming. With many user-definable parameters,
the STU
111/SECTEL can be tailored to your individual
requirements.
• Ease of use. The adjustable message display shows the status of
all STU 111/SECTEL modes and functions.
• Dialing flexibility. The STU 111/SECTEL is compatible with both
tone and pulse dialing systems.
• Adjustable handset speaker and ringer. The handset speaker
and ringer volume can be set
to meet your individual needs.
• Standard telephone with speed-dialing capability.
• No batteries to replace.
In addition to the features listed above, the STU 111/SECTEL (Bell
1A2) Model offers multiline operation, an intercom function, a
HOLD feature, and LED indicators for these additional functions.
Motorola also offers a STU 111/SECTEL which is directly
compatible with the
AUTOVON telephone network.

There are two levels of security offered with the STU 111/SECTEL
family. The STU 111/SECTEL 1000 terminal is a U.S.
Government -approved device designed for protection of
"sensitive" or classified information. The STU 111/SECTEL 2000
terminal is U.S. Government·approved for unclassified but
"sensitive" communications, providing the highest level of
security commerically available. Figure l ·2 shows the STU Ill/
SECTEL family. Refer to Chapter 9, Models and Accessories, for
more information on the available models.
Phone Line Interface
Phone line connection is made by an industry standard RJ
11 C
modular phone jack. An optional RJ45S connection is also
available.
