Jt-102 Joint Systems Capabilities &
Limitations Questions And Answers
Gateway Disadvantages 1. can result in loss of data source information, loss of tactical
data, conversion errors, and track number differences.
2. difference between the bandwidth, and information carrying capacity, of the interfaced
networks. difference in bandwidth could result in serious latency problems
3. potential for data looping.
Data Looping occurs when a unit receives the same data on two or more TDLs, or
receives their own information back.
JADSI modular, reconfigurable, real-time, command and control system.
4 Major Components of JADSI 1. Tactical Data Link Gateway (TDLG)
2. Command and Control Host (C2H)
3. Tactical Workstation (TW)
4. TacView/C2 (Ability to Rx J16.0 Imagery)
, On the JADSI, how many TDL circuits and tracks can the TDLG support? 32 TDL
Circuits and up to 16000 tracks
JRE-GW The JRE-GW provides the JICO with multi-point, interoperable, BLOS Link 16
connectivity between Link 16 networks and Service C2 platforms
How many J-Series messages and how fast can the JRE-GW process? 20,000 J-Series
messages every 12 seconds.
JRE-GW Server The JRE-GW server is a transit case enclosed system providing both the
required TDL hardware connections as well as the operator HMI.
JRE Client The JRE Client is the JRE HMI software configured to run on a PC, notebook
computer, or handheld computer. The JRE client does not have the hardware required to host
actual TDL circuits. It serves a control for the JRE-GW Server equipment.
What are the following JRE-GW Interfaces? • 4x RS-232
o Serial J, JREAP B
• 4x RS-422
o Sat TDL-J, JREAP A, JREAP B, Class 2M, MIDS LVT-2
• 2x 1553
