SHIFT FREQUENCIES

Shifting frequencies or changing frequencies is accomplished to allow for stronger propagation of the circuits. When the signal strength begins to decay, the operator will shift frequencies to another or stronger frequencies in accordance with naval and local instructions.

TRANSMIT OR RECEIVE CRYPTOGRAPHIC KEYING MATERIAL VIA OTAT/OTAR

Some of the new cryptosystems will use a 128-bit electronic key that is called over-the-air-rekey (OTAR) or over-the-air transfer (OTAT). Using this system reduces the amount of physical keying material held on board a command.

The key can be extracted using a KYK-13 or KYX-15/KYX-15A. The key is then loaded into another cryptosystem.

For amplifying information, refer to Procedures Manual for Over-the-Air Transfer (OTAT) and Over-the-Air Rekey (OTAR) and Field Generation and Over-the-Air Distribution of Tactical Electronic Key, NAG-16/TSEC.

ANALYZE NETWORK CAPACITY AND RELIABILITY

When trying to analyze a network's capacity and reliability, you must first establish the criteria or level at which you wish the system to work. Does the network have set boundaries, or can it be expanded to include updated or new parameters? Many avenues can be explored to find the most efficient methods and levels at which a network can work.

Accurate documentation is a key factor for showing the user what, where, total numbers, and reliability of the network.

You will find that with the correct numbers you can see where a system or network is falling short or surging ahead of the set projection data.

SUMMARY

In this chapter you have been introduced to communications systems, networks, and administration concerns in their most basic forms.

Not all of our work is concerned with strategic or tactical operations. Establishing circuits or networks, quality control, and the various operations of the STUIII are just a few of the many facets of our complex and diverse jobs.
