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. 1-16 Automatic message logging; Automatic message continuity checks; On-line message preparation and storage; Backup control and operation; High-speed data interface; On-line operational readiness testing; Quality monitoring with computer aid; Message error analysis; Circuit status and record-keeping functions; Construction of communications circuits; and Ability to act as a CUDIXS special or primary
