Receive Net Update ERF from NCS (Special Operator Task 4)

TM 11-5820-890-10-8

Receive Net Update ERF from NCS (Special Operator Task 4)

5.5g.

DESCRIPTION

This task is performed when there is a requirement to change, or

update, some element of FH data, and the operational situation makes

it impossible or impractical to disseminate the new data by physical

connection of ANCD to ANCD. In such cases, the NCS alerts net

operators that they are to receive a net update ERF Operators then

change the RT FCTN from SQ ON to LD, remaining on the operational

channel. The NCS sends the ERF on the operational channel (not on

MAN as during a Cold Start net opening). Once the net update ERF has

been sent, the new data may be made effective immediately or stored

for later implementation. ERF, Broadcast, and OTAR constitute the

means by which FH data, SOI information, and COMSEC key (TEK

only) can be transferred electronically from one location to another.
