CHAPTER 1
CENTER OPERATIONS
Upon completing this chapter, you should be able to do the following:
Identify the procedures for transmitting messages via automated systems and
manual circuits.
Identify the procedures for monitoring and reporting of circuit backlogs.
Identify the steps to verify broadcast number continuity.
Determine the procedures for preparing, updating, and verifying the
command guard list (CGL) and the master station log (MSL).
Identify the procedures to verify STU-III systems parameters for remote/dial-
in users and explain the need to set up and operate the STU-III terminals with
remote/dial-in users.
Determine the procedures for the preparation of the communications plan.
Identify the steps to reset communications systems to RADAY.
Determine communications protocols applied to circuit set up/restorations.
List the steps to activate, deactivate, and place communications circuits in
standby, set up, or restoration.
Identify the procedures to transmit or receive cryptographic keying material
via OTAT/OTAR.
Define the steps to analyze network capacity and reliability.
Telecommunications capabilities are continually
advancing as technology improves. Because of
advances in technology, we are seeing great
improvements in the quality and speed of
communications, and an increase in our information
transfer capabilities. The Navy’s modern automated
systems greatly reduce writer-to-reader times in
message handling, and the volume of messages that can
be processed is steadily increasing.
ASHORE AUTOMATED
TELECOMMUNICATIONS SYSTEMS
Two new shore command systems that are coming
on-line in the 1990s are the Navy Standard Teleprinter
Ashore (NSTA) and the Manual Relay Center
Modernization Program (MARCEMP). We will
discuss these two new systems as well as the other in-
place automated shore systems and their interface
components.
NAVY STANDARD TELEPRINTER
ASHORE
With the introduction of the Navy Standard
Teleprinter (NST) at afloat commands, there was a need
to replace antiquated communications systems ashore
with a system compatible with the NSTs. To meet this
need, the Navy has developed the Navy Standard
Teleprinter Ashore (NSTA) program.
The heart of the NSTA program is the Personal
Computer Message Terminal (PCMT) and its
