Q

201.1 Define and state the purpose of FSM. [ref. d]

A
  • Fleet SIPRNET Messaging (FSM) was developed to provide an alternate method of delivering General Service (GENSER) organizational messages classified up tp Secret to fleet units via the SIPRNET.

201.3 State the purpose of MMS. [ref. g]

A
  • The Multi-level Mail Server (MMS) provides a store-and-forward system for electronic exchange of organizational messages through unattended dial-up communications links from the GateGuard system using the RIXT protocol.

Q

201.8 Define and state the purpose of MCS. [ref. d, g]

A
  • The primary purpose of the Regional MCS is to provide PLA-to-Routing Indicator (RI) look up and assignment. After receiving a message from the host NOVA System, the Regional MCS will validate the message, assign the appropriate RI(s) and return the message to the NOVA for delivery. If invalid PLAs are found by MCS, the MCS will automatically generate a service message to the originator.

Q

201.16 Explain whether each master station can radiate each other’s CUDIXS and their limitations. [ref. b]

A
  • Only limitations are geographical. i.e. only sites that are within sight of the satellite can provide the uplink necessary to hold the radiating function.
17
Q

201.17 State the purpose of MPS-800. [ref. j]

A
  • The TANDBERG MPS enables sites on IP (H323 and SIP), ISDN and High Speed Serial (V.35/RS449/RS530 w/ RS366 support) to participate in meetings with each other, and at the same time it offers superior quality and ease of use in one fully-featured multipoint control unit, MCU. The TANDBERG MPS may also include the optional Gateway functionality

    b. MLA –MAIL LIST AGENT - Provides a collective addressing capability for DMS
    c. MFI – infrastructural-level component that provides protocol conversion between DMS MTS and the DTH legacy-messaging environment.
    d. PCMT - Personal Computer (PC) based message processing system used at shore-based Navy fleet relay centers, telecommunications centers, and remote terminal sites. PCMT improves the speed, accuracy, and reliability of message handling functions. PCMT is capable of processing both narrative and data pattern messages. Message traffic within the PCMT is relayed to collocated AST for exchange with AUTODIN. It can be configured as a backside terminal to the (NAVCOMPARS), Nova, or MDT host system.
    e. DIT - A directory information tree (DIT) is data represented in a hierarchical tree-like structure consisting of the Distinguished Names (DNs) of directory service entries.
    f. BMTA – Backbone Message Transfer Agent – Functions as high level store-and-forward switches within the DMS MTS
    g. LMTA – Local Message Transfer Agent – Functions as an intermediate level switch that stores and forwards messages.
    h. VFC – Virtual Fortezza Card
    i. CAW – Certificate Authority Workstation – CAS is a NSA certified and approved workstation that provides enabling technology supports messaging security services of confidentiality, authentication, and non-repudiation.
    j. X.400 – Exchange Directories - X.400 is a suite of ITU-T commendations that define standards for Data Communication Networks for Message Handling Systems (MHS) — more commonly known as “e-mail”.
    k. X.500 - Exchange Directories - .500 is a series of computer networking standards covering electronic directory services. The X.500 series was developed by ITU-T, formerly known as CCITT. The directory services were developed in order to support the requirements of X.400 electronic mail exchange and name lookup
