Messaging (PS 101) Flashcards
Why units com shifting to FSM need a legacy route?
Units that lose primary delivery paths are cautioned that if primary and secondary (ZOV Path) are lost, category 1 and 2 messages will be sent to tertiary paths listed in the latest COMMSHIFT on file at the Master Update Authority.
Purpose of FSM?
Fleet Secret Internet Protocol Router Network
Alternate method to deliver general service organizational messages classified up to Secret to fleet units via SIPRNET.
MMS?
Multilevel Mail Server
Provides secure dial in services to up to 500 subscribers.
Secure means of exchanging organizational messages between remote and local subscribers.
Uses GateGuard terminal and STU-III so the most remote subscriber can dial in to MMS and receive organizational messages.
MUA?
Master Update Authority
Provides a means for service center operators to correct and resubmit messages rejected from the Message Conversion Center.
DUSC?
Directory Update Service Center
Produces directory updates for the;
Defense Message System
Update Authority Component
And database updates for FMX
FMX?
Fleet Message Exchange
Replaced the Naval Computer Processing and Automatic Routing System (NAVCOMPARS). FMX routes messages to stations using routing indicator.
State the sites that have a FMX/DUSC system?
NCTAMS PAC Honolulu, HI
NCTAMS LANT Norfolk, VA
State the master and alternate DUSC stations?
NCTAMS PAC Honolulu, HI
NCTAMS LANT Norfolk, VA
Purpose of MCS?
Message Conversion System
Assign’s RI’s to PLA’s. MCS are transitional
systems to aid customers in the migration from AUTODIN to DMS. Even though these systems are transitional, both are designed to remain viable until the phase-out of the AUTODIN system is completed
State the world-wide MCS RI.
RHMCSUU
RI?
Routing Indicator
Used by FMX to route messages to units
OSRI?
Originating Station Routing Indicator
This identifies the commandoriginator by assigned AUTODIN or Fleet routing indicator (FRI)
DSRI?
Destination Station Routing Indicator
Follows two hyphens (–) and consists of a six or seven character code identifying the station or system the message will be delivered to upon receipt by Autodin.
NARC?
First four letters of a routing indicator assigned to servicing NCTAMS/NAVCOMTELSTA
FRI?
Last three letter of a routing indicator assigned to a unit by the Master Update Authority Honolulu, HI.
RI that MCS will assign to an invalid PLA within a transmitted message?
RUBDPLA
VZCZCYKN001?
Transmission Identification
The VZCZC indicates the start of a message. It is then followed by a 3 letter station or channel designator (YKN=USS YORKTOWN). The station/channel designator is then followed by a 3 digit sequential number of transmissions.
Message Header?
The header is a 43-69 character starting point, and MUST BE LETTER PERFECT.
Julian Date?
Three digits (The Julian Date will start on the first of January as 001, and will continue to increment by one each day until the last day of December as 365 [or 366 on leap years]).
ZNR UUUUU
Security Warning
This format line will begin with the appropriate 3 letter Operating Signal, followed by a classification character repeated five times. ZNR will be used with unclassified message traffic, while traffic that is of Confidential or higher classifications will use the OPSIG ZNY, for example: ZNY CCCCC.
Date-Time-Group?
The first two digits of the DTG represent the day, the next four represents the time. Z represents the time zone (Zulu time zone). After the time zone indicator there will be a space, the three letter month representation, another space, and then finally the two digit represents the year.
Originator?
Plain Language Address of the station that drafted the message.
Action Addressee?
The prosign “TO” followed by an addressee’s routing
indicator, and the Plain Language Address Designator (PLAD) who is responsible for taking “action” on the message. The practice of putting a Routing Indicator beside the PLAD is known as siderouting.
Information Addressee?
The prosign “INFO” followed by an addressee who only
needs to be informed of the messages content. The INFO addressees have no need to take action on the message.
Exempt Addressee?
The prosign “XMT” followed by an addressee who would
have been included as a part of an AIG or CAD, but the originator does not want that station to receive the message. This Format Line is optional, and often is not used
BT?
Break - This format line uses the PROSIGN ‘BT’ which means Break. It provides a break between the heading of a message and the actual text of the message.
TEXT?
Text consists of the classification and the body of the message. The Text portion of the message has several elements. Its composition is normally composed by use of an automated computer application such as MTF
Editor, or TURBO PREP.
0001?
Validation- This end of message verification duplicates the SSN or Station Serial Number
This will verify that a message is complete.
NNNN?
unique characters recognizable by computer systems as representing the end of a message.
ZBZ?
An Indicator of Signal quality
ZUJ?
Stand by
ZEV?
Request you acknowledge message/Message is acknowledged
ZUG?
Negative
ZUE?
Affirmative
ZES?
Your message….has been received…
(1) incomplete
(2) garbled
.Request retransmission.
The purpose of CUDIXS?
Common User Digital Information Exchange Subsystem.
CUDIXS provides a 2400 baud full duplex interface, it’s a shore based store and forward messaging system.
Sites that have CUDIXS suites and their capabilities?
NCTAMS PAC,
NCTAMS LANT,
NCTS Guam,
NCTS Naples
The two NCTAMS, NCTS GUAM, and NCTS Naples are equipped with CUDIXS. Each site has at least three CUDIXS suites and the capability to operate two full and one “mini” configuration simultaneously.
MPS-800?
Bridges the DMR/KG84A to the CUDIXS workstation.
Fleet multi-channel broadcast packages?
PMUL: Fleet Multichannel Broadcast System for PACFLT
LMUL: Fleet Multichannel Broadcast System for LANTFLT
IMUL : Fleet Multichannel Broadcast System for Indian Ocean
BCA?
The Broadcast Control Authority (BCA) is the central hub where all message traffic sent to or received by submarines and shore stations gets disseminated.
BKS?
Broadcast Keying Station (BKS). The BKS introduces message/facsimile traffic into the Fleet Broadcast Network by generating a key stream of broadcast-bound information to the BCS for specific channel allocation before being forwarded to the BRS for broadcast transmission.
BCS?
Broadcast Control Station (BCS). The BCS provides all the technical aspects of affecting a Fleet Broadcast. BCS and BRS are normally integral parts of a NCTAMS. Stations that possess a TD-1150 and have connectivity to a particular BKS and BRS have the ability to perform BCS functions.
BRS?
Broadcast Radiating Station (BRS). The BRS radiates the broadcast signal to the Fleet via Satellite, Super High Frequency (SHF), and/or Low Frequency (LF).
TMG?
Tactical Message Gateway
MLA?
The Mail List Agent (MLA) provides a collective addressing capability for DMS. The MLA receives messages addressed to a collective address called a Mail List and redistributes them to those recipients who are members of the Mail List.
MFI?

PCMT?
Personal Computer Messaging Terminal
Secondary/alternate msg. system used to send out messages in case NREMS (primary system) goes down.
DIT?
Defense Information Tree (DIT) The directory tree provides a way for directory data to be named and referred to by client applications. The directory tree organizes data. It also determines how data is partitioned across multiple servers.
BMTA?
Backbone Message Transfer Agen)
BMTA’S serve as independent store-and forward message switches.
LMTA?
Local Message Transfer Agent
The LMTA functions as an intermediate-level message switch that stores and forwards messages across a fully interconnected switch fabric called the MTS.
