CHAPTER 5
NEW TECHNOLOGY IN DATA COMMUNICATIONS
INTRODUCTION
The current Link-11 and Link-4A systems are being updated with new equipments. The Data
Terminal Set AN/USQ-125 is currently replacing the older Link-11 data terminals. In addition, new
communications systems, such as the Command and Control Processor (C2P) and the Joint
Tactical Information Distribution System (JTIDS), are quickly becoming commonplace on
various platforms in the Navy. This chapter will introduce you to some of the changes taking place
and the basic features of some of the new systems.
After completing this chapter, you should be able to:
Describe the various components of the AN/USQ-125 Data Terminal Set.
Describe the operation of the AN/USQ-125 in a typical Link-11 system.
State the purpose of the Joint Tactical Information Data System (Link-16).
Describe the components of the Link-16 system.
State the function of the Command and Control Processor (C2P) system.
Describe the components of the C2P system.
AN/USQ-125 DATA TERMINAL SET
The AN/USQ-l25 data terminal set is the newest
Link-11 data terminal set in the Navy. It is quickly
replacing older DTSs, such as the AN/USQ-36 and
the AN/USQ-59. There are several configurations of
the AN/USQ-125. The CP-2205(P)(V)/USQ-125 data
terminal with the MX-512P/RC Remote Control Unit
is one configuration.
The other configuration is
CP-2205(P)(V)2/USQ-125 data terminal with a
personal computer (386 or better) running the
MXPCR software. The personal computer serves the
same function as the remote control indicator in this
configuration. The standard interface configuration of
the AN/USQ-125 is shown in figure 5-1. In this
chapter, we examine the data terminal and the
functions of the control indicators, either the
MX-512P/RC or a personal computer.

THE CP-2205(P)(V)/USQ-125 DATA TERMINAL
The CP-2205(P)(V)/USQ-125 data terminal is a
compact, state-of-the-art data terminal that is mounted
in a standard 19-inch equipment rack. The data
