Transmit Updated FH Data Via Net Update ERF (Special NCS Task 1)

DESCRIPTION

This task enables the NCS to electronically transmit new FH data to net

operators when distribution by physical connection of ANCD to ANCD

is impossible or impractical. This procedure may be used to update

(change) hopsets, TSKs, net IDS, and sync time. The task involves

alerting net operators, sending the ERF using the net operational

channel, confirming receive of the ERF, and making a communications

check when the changed FH data is put into effect.
