(Blank)
MTA
physical configuration and operational procedures to make up a MTN
Define Partitioned Variable Mode (PVM)
TSEC and MSEC variables may be different or the same, info is divided into multiple cryptonets using different MSEC variables. IOT Rx messages, a JU must be a net and cryptonet member.
What amount of messages are received IOT reach fine sync.
3 RTT Messages
Define NPG 9
Air Control - lets C2 JUs control non-C2 - uplink and downlink parts.
What are data filters?
inhibit the transmission of forwarding of data on a link or to inhibit data received on a data link from being entered into an IU's database.
MTN=???
MTA + Data + Voice Circuits
Simply explain Cryptovariable logic label (CVLL)
A binary key used to encrypt and decrypt Link 16 data.
Define NPG 5?
Initially used for non-C2 JUs to report High Update Rate (HUR) PPLIs. Current network design techniques rarely use this NPG.
Define NPG 21
Ballistic missile defense operations - Patriot, THAAD, and TMD platforms
What are Transmit filters?
inhibit the transmission of certain data which will be specified by filter type
IER acronym
Information Exchange Requirements
What are Network Participation Groups (NPGs)
PPLI message transmitted in NPG 5&6. A method for Link 16 to organize and manage capacity. The building blocks of the network where designers allocate groups of time slots to different functional NPGs. Each NPG has specific J-series messages associated with it.
Define NPG 6?
Typically used for all PPLI and system status reporting, to include non-C2 JU HUR PPLIs.
what specifies the procedural requirements and defines the message and data element translations
MIL-STD-6020
What are Receive Filters?
inhibits the reception of data which is specified by the type of filter being employed.
IER is defined as?
The requirements for information to be passed between and among joint forces and organizations
Define J-Series Messages
Made up of initial, extension, and continuation. The language of Link-16 capable weapons systems that enables them to speak to one another.
Define NPG 7
For the reporting of all surveillance tracks, lines, areas, points, and messages. Accounts for largest percentage of time slots assigned.
What is Data forwarding?
The process of receiving data on one digital data link and outputting the data, using proper format and link protocols, to another type of digital data links
What are Forwarding filters?
inhibit or limit the forwarding of data received from one link on to another
Acronym DCA and its purpose
Defensive Counter Air-
Protect friendly forces, assets, population centers, and interests from air and missile threats
Employ a mix of weapon, sensor, communications, and command and control (C2) systems integrated from all components
What message types can be received in Coarse Sync
ALL TYPES but cannot transmit
Define NPG 8
C2 JUs order and report status on weapons engagements, controlling unit changes, tactical pairings, and network enabled weapon (NEW) coord. Typically C2-to-C2, but can be non-C2.
What are Data loops?
allow one or more units to receive the same info from more than one data path
Why use filters
-prevent an individual IU data base from being overloaded
-to avoid overloading a specific data link
-to avoid overloading a L16 NPG transmit buffer
-to divide r2
-to control transmission and reception of special processing indicator (SPI)
-control transmission and reception of data based on treaties or National restrictions
