Definition of Special NCS Tasks

There are five tasks categorized as special for SINCGARS NCS

WHAT ARE THEY?

personnel. These five tasks enable a SINCGARS NCS to electronically

transfer FH data (to include a TSK), SOI information, and COMSEC

keys (TEK only).

The preferred method of updating these categories of data is by

physical connection of ANCD to ANCD. When the tactical situation

makes physical transfer impossible or impractical, these electronic

transfer means may be used.

All SINCGARS NCS personnel should receive at least familiarization

WHAT'S REQUIRED?

In units which anticipate frequent

training in these tasks.

mission-related requirements for electronic data transfer, NCS

operators should be trained to proficiency. In that many units will but

rarely have a need to use electronic data transfer, the assistance of the

Signal Offrcer/NCOs may be required for their NCSs to perform these

tasks correctly.

Summary of Special NCS Tasks

Transfer Updated FH Data via Net Update ERF

SPECIAL NCS TASK 1:

Used for electronic transfer of FH data (hopset, net ID, TSK) from one

location to another, Net update ERF may also include a change in sync

time if desired.

Transmit SOI information Using the Broadcast Mode

SPECIAL NCS TASK 2:

This IS the procedure used for electronic transfer of SOI information

from one location to another. Because of the time required to transfer

SOI data by Broadcast, each transmission is normally limited to one

time period.

Send TEK to Other NCSs Using the MK Method of OTAR

SPECIAL NCS TASK 3:

This is the principal method of electronically transferring a TEK from

one location to another. The MK (manual key) procedure moves TEK

from a Source ANCD, through the Source NCS RT through the Target

NCS RT, into the Target NCS's ANCD.

Send TEK to Net Operators Using the AK Method of OTAR

SPECIAL NCS TASK 4:

This is a method for disseminating a new TEK by electronic transfer

with a net. The procedure moves the new TEK from the NCS's ANCD,

through the NCS's radio, directly into the radios of net operators.

Receive and Store TEK Sent by MK Method of OTAR

SPECIAL NCS TASK 5:

This is the procedure followed by Target NCSs when a Source NCS

sends a TEK by MK OTAR (Special NCS Task 3, above). This task

enables the receiving NCSs to store the electronically transmitted TEK

in an ANCD, where it IS readily available for further distribution within the

unit when required.
