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.

The STU 111/SECTEL's menu-driven software provides users with
information via the message display. The 32-character interface is
capable of displaying over 150 different messages, including
configuration prompts, operational status, and error information.
Chapter 8, Troubleshooting, of this User's Guide contains those
display messages which inform the user when the terminal is not
operating properly or when it has failed to perform a selected
function.
Appendix A, Display Messages, contains configuration prompts
and operational status display messages, any of which may appear
in
the course of normal operation.

To establish a secure link, the STU 111/SECTEL must be Ailed with
cryptographic data. This can be accomplished in
two ways, by an
operational All or a seed All. An operational All, performed by your
security representative, will give the terminal all required data. A
seed All must be converted to an operational All by calling a Key
Management Center (KMC) to obtain the necessary
crypto data.
