System Performance/Message Accountability
CUDIXS provides a shore operator with several
means of monitoring system performance and
maintaining message accountability for all messages
processed by the CUDIXS NCS. Specifically, the
system assigns sequence numbers to all messages
processed, provides link status, traffic statistics, and
system summary information in system reports. The
system also allows the operator to assign parameter
values that control net operations and to generate
various alerts concerning immediate communications
difficulties.
System Interfaces
CUDIXS serves as an extension of AUTODIN by
storing and forwarding messages, normally without
need for human intervention. CUDIXS interfaces with
AUTODIN via the NAVCOMPARS and processes
narrative traffic for general fleet communications
teleprinter messages.
In accomplishing its tasks, CUDIXS supplements
the traffic responsibilities previously assumed by ship-
to-shore and broadcast HF circuits. CUDIXS can
recognize EMERGENCY COMMAND, FLASH,
IMMEDIATE, PRIORITY, and ROUTINE messages
on a first-in-first-out (FIFO) basis within precedence.
Through system reports, the operator has the following
capabilities:
Detailed information on every message
processed by CUDIXS;
Overall statistics on the volume of message
traffic processed over the link; and
Information on the quality of link
communications with each net subscriber.
COMMUNICATIONS DATA PROCESSING
SYSTEM
The Communications Data Processing System
(CDPS) provides the USS Tarawa (LHA-1) class ships
with the necessary communications hardware and
software to process narrative traffic and to ensure circuit
reliability. CDPS is one of the most complex of the
automated systems afloat and offers the following
capabilities:
Automatic broadcast screening;
Frequency management;
subscriber.
As with many of the automated systems, the
operator has the ability to modify system configuration
from the control console. The operator must know how
to properly use, operate, and perform system changes.
Your job will involve setting up and operating
input/output (I/O) devices. Some systems allow the
operator to patch receivers, transmitters, modems, and
antennas directly from the console.
As a Radioman, part of your routine duties will be to
energize electronic equipment and monitor power
levels. In the event of primary power failure, equipment
must be brought up on emergency or back-up power
systems. Many of the automated systems in use today
have uninterrupted power sources (UPS) or battery
backups to preclude a complete system failure.
For more information on power requirements for
individual components, refer to the equipment technical
or operator manuals. You should become familiar with
emergency power requirements and procedures prior
to an actual emergency.
SUBMARINE SATELLITE INFORMATION
EXCHANGE SUBSYSTEM
The Submarine Satellite Information Exchange
Subsystem (SSIXS) provides the commanding officers
of SSN and SSBN submarines with an optional satellite
path to complement existing VLF/LF/HF broadcasts.
The subsystem provides a rapid exchange of teleprinter
information between SSN and SSBN submarines and
shore stations.
