Jt-102 Multi-Tactical Data Link (Tdl)
Network (Mtn) Operations (Unit 22)
Questions With Solutions
Name the steps of MTN initialization. - Equipment Prep and OPTASK LINK Data Entry
- Establish Voice Communication
- Establish Each TDL Independently
- Forwarding Participating Unit (FPU)/Forwarding Reporting Units (FRUs) Begin Operations
(This step lets platforms using legacy TDLs generate a coherent legacy TDL picture. Note: FJUs
are NOT operating at this point)
- TDL Managers Report to JICO/JICC Watch Officer
- Legacy TDLs Inhibit Track Transmissions
- Forwarding JTIDS Units (FJUs) Go Active
- PUs/RUs Go Active
, - Begin TDL Maintenance Operations
At what point in the MTN initialization should CIUs should discontinue operations on non-Link
16 TDLs, PUs should go radio silent, RUs should go to Limited Transmission of Data (LTD)
mode. FPUs and FRUs should continue to operate? Legacy TDLs Inhibit Track
Transmissions
At what point do the PUs and RUs then correlate their local track data with the Link 16 track
data that is being forwarded to them? When Forwarding JTIDS Units (FJUs) Go Active
What happens when there are forwarder outages for more than 60 seconds? With
forwarder outages of more than 60 seconds, remote tracks are lost, Reporting
Responsibility R2 shifts occur, and commands and orders might not be received, resulting in a
significant loss of situational awareness
What should a TDL manager do when a forwarder switch occurs and a switch has been made
making the original standby forwarder the new primary forwarder? Once a forwarder
switch occurs, the TDL Manager should designate a new standby data
forwarder and ensure the MTN can be configured appropriately.
Where should changes to the data forwarder be announced AND where should coordination for
changes happen to the max extent possible? The DCN.
