Question 9

what are AFCQCCs?

Answer 9

guides used primarily by quality assurance (QA) to help determine equipment condition, maintenance quality, and maintenance management effectiveness.

Question 10

why are there no ATCALS equipment AFCQCCs?

Answer 10

ATCALS work centers perform self inspection evaluations using the Air Traffic Systems Evaluation Program (ATSEP) checklist published in accordance with AFI 13-204, Volume 2

Question 11

What are AFCSIs?

Answer 11

provide a means to issue inspection and servicing requirements, operational performance checks, and special maintenance instructions related to standard communications equipment for which formal TO procedures are not published. They may also provide the means to issue optional or temporary modifications on communications equipment.

Question 14

what facility ground subsystem is also known as the safety ground?

Answer 14

the fault protection subsystem

Question 15

what is bonding?

Answer 15

the establishment of a low-impedance path between two metal surfaces

Question 16

what does the term bond refer to?

Answer 16

the establishment of a low-impedance path between two metal surfaces

Question 17

what is the maximum resistance for bonds in the earth electrode subsystem?

Answer 17

it should not exceed a resistance of 1 milliohm

Question 18

what type of bond is not allowed for the lighting protection and fault protection subsystems?

Answer 18

soft solder

Question 19

what are the two standards for shielding effectiveness?

Answer 19

for shielded enclosures and global shielding is 50dB. The standard for equipment is National Security Telecommunications and Information Systems Security advisory Memorandum (NSTISSAM)/TEMPEST 1-92, Level I.

Question 20

Name at least three less obvious conductive paths for the escape of compromising emanations.

Answer 20

The power lines (and the electrical metallic tubing [emt] they run in), extension cords, signal ground wires, alarm signal lines, fire suppression piping, air conditioning and heating ducts, water pipes, building metallic members, and so forth.

Question 21

What is considered red equipment?

Answer 21

equipment that processes clear-text classified information

Question 22

What is considered black equipment?

Answer 22

equipment that processes encrypted or unclassified information.

Question 23

what are the two categories of batteries?

Answer 23

primary and secondary cells

Question 24

What is another name for primary cell batteries?

Answer 24

it is also called a dry cell because of its moist paste electrolyte

Question 25

what primary battery cell has a nominal voltage of 1.5volts, a very low internal resistance, and a high service capacity?

Answer 25

alkaline
