b. CUDIXS:
Common User Digital Information Exchange Subsystem has the capability to both send and receive narrative shipboard message traffic.
c. VERDIN:
VLF Digital Information Network is a broadcast system that provides a highly reliable and secure system for worldwide delivery of operational, tactical, and administrative messages from the Fleet Submarine Broadcast System (FSBS) and Minimum Essential Emergency Communications Network (MEECN).
d. NOVA:
Automated Message Store and Forward is a switching system that provides automated readdressed and quote functions for authorized users.
e. IBS:
INTEGRATED BROADCAST SYSTEM disseminates threat avoidance, targeting, maneuvers, force protection, target tracking, and target/situation awareness information, and will be continuously refined by data from national, theater, and tactical sensors.
g. DMS (DEFENSE MESSAGE SYSTEM):
(DEFENSE MESSAGE SYSTEM): Employs the messaging and directory services using internationally recognized COTS-based X.400 and X.500 messaging and directory products.
f. INMARSAT:
International Maritime Satellite is a critical communications path for SIPRNET, NIPRNET, and POTS (plain-old telephone system) ship-to-shore communication for all Navy ships less the CV/CVN/LHA/LHD/AGF and LCC classes. This multipurpose SATCOM system provides both simultaneous voice and IP data up to 128 Kbps.
NREMS (NAVY REGIONAL ENTERPRISE MESSAGE SYSTEM):
(NAVY REGIONAL ENTERPRISE MESSAGE SYSTEM): Provides web-based messaging capability that allows users to send and receive DMS messages using a web browser or via SMTP.
AMHS (AUTOMATED MESSAGE HANDLING SYSTEM):
(AUTOMATED MESSAGE HANDLING SYSTEM): Implements on-site redundancy and full Continuity of Operations Planning (COOP) capability between NCTAMS LANT and NCTAMS PAC.
h. VTC:
Video Teleconferencing Service is an extension of traditional telephony technologies with the added feature of being able to see the person or persons with whom one is talking.
i. DCO:
Defense Coordinating Officer, will help provide war fighters and supporting elements with some of the tools required for collaboration during engagements.
109.3 Discuss GINGERBREAD and explain the procedures involved.
Gingerbread indicates that an unauthorized person is present on a circuit. The only proper response to this is “Roger out” and communications are to cease on that circuit
109.4 Discuss BEAD WINDOW and explain the procedures involved.
Occurs when the previous transmission may have disclosed unauthorized EEFI information and uses a code word and a number combination which is transmitted immediately by any net member to the unit disclosing the EEFI. Proper response for a net member receiving a BEADWINDOW will be “ROGER OUT” using proper net call signs.
109.5 Discuss types of disclosures afforded protection by the EEFI list.
Essential Elements of Friendly Information – designed to protect friendly intelligence by granting it the same classification level of our own corresponding intelligence to include: position, capabilities, operations, personnel, COMSEC, and inappropriate transmissions (Wrong Circuit) of friendly and enemy combatants and their systems.
109.6 Define RIVER CITY and state when it is utilized.
River City is an OPSEC countermeasure. There are various levels that further restrict the outbound transmission/radiation of communication systems and RADAR.
109.7 Discuss JSIR (Joint Spectrum Interference Resolution) to include the following: Meaconing:
a system of receiving radio beacon signals and rebroadcasting them on the same frequency to confuse navigation.
109.7 Discuss JSIR (Joint Spectrum Interference Resolution) to include the following: Intrusion:
The intentional insertion of EM energy into transmission paths in any manner, with the objective of deceiving or confusing operators.
109.7 Discuss JSIR (Joint Spectrum Interference Resolution) to include the following: Jamming/Inference:
The deliberate radiation, re-radiation, or reflection of EM energy for the purpose of preventing or reducing an enemy’s effective use of the EM spectrum with the intent of degrading or neutralizing the enemy’s combat capability.
109.7 Discuss JSIR (Joint Spectrum Interference Resolution) to include the following: Spectrum management:
the fine-tuning of RF to reduce crosstalk and converging of different communication systems to maintain COMSEC.

109.10 State the purpose of an OPTASK COMMS
Operational Tasking Communications are a means used by which the United States Navy and Allied Navies distribute afloat communications plans.
109.11 State the purpose of a COMMPLAN.
A Communications Plan provides the communications planner with an automated method of drafting the OPTASK COMMS message.
109.12 State the purpose of a TSO.
A Telecommunications Service Order is the authorization from Headquarters, DISA, a DISA area, or DISA-DSC to start, change, or discontinue circuits or trunks and to effect administrative changes.
109.13 State the purpose of a TSR.
A Telecommunications Service Request requires additions, deletions or changes in existing Defense Communication System circuits.
109.14 State the purpose of a COMSPOT/ Communications service advisory.
A COMSPOT is a report indicative of issues, expected outages, or an outage of a circuit(s) lasting more than 30 minutes. Report is made to NCTAMS and DISA.
109.16 State the purpose of OTAT
- Over-the-Air Key Transfer (OTAT): Electronically distributing key without changing the traffic encryption key used on the secured communications path over which the transfer is accomplished. (Transmitting electronic key mat for new day, month, etc.)
109.15 State the purpose of Key Management Infrastructure (KMI).
Prescribes the minimum policies for issuing, accounting, handling, safeguarding, disposing of COMSEC (Communications Security) material, and the application of cryptographic/physical security measures to COMSEC material and facilities.
109.16 State the purpose of OTAR
- Over-the-Air Rekeying (OTAR): Changing traffic encryption key or transmission security key in remote crypto-equipment by sending new key directly to the remote crypto-equipment over the communications path it secures. (The reception of the new key mat for new day, month, etc.)
109.18 State the purpose of Emissions Control (EMCON).
Prevents an enemy from detecting, identifying, and locating friendly forces and is used to minimize electromagnetic interference from friendly systems.
109.17 Describe TEMPEST.
Transient Electromagnetic Pulse Emanation Standard is the code name given to the investigation, study, and control of compromising emissions from telecommunications and automated information processing systems.
