Q

What does SIPTO guidance help to ensure?

A

Installation projects are accomplished safely with special emphasis on personnel and equipment safety.

2
Q

Within how many inches is the first label placed on the cable from the connector and how will it be marked?

A

within 12 inches and will be marked ‘to’ and will indicate the bay, equipment shelf, terminal block and plug or jack to which the connector will mate

3
Q

within how many inches from the first label would the second label be placed and how will it be marked?

A

the second market will be placed within two inches of the first and will be marked ‘from’

4
Q

what is the purpose of the binder in a telecommunications cable?

A

to group by spiraling around a specific number of pairs that replicate in color multiple times throughout a cable

5
Q

what is the color code for the ‘tip’ or ‘primary’ color groups?

A

white, red, black, yellow, and violet

6
Q

what is the color code for the ‘ring’ or ‘secondary’ cable pairs?

A

blue, orange, green, brown, and slate.

7
Q

what are the colors of the two pairs that are reversed in a T568B network crossover cable?

A

white/orange and orange; white/green and green.

8
Q

why should you control the number of splices in a fiber cable?

A

to minimize transmission loss and to reduce the installation time and expenses generated due to splices

9
Q

what are AFCQCCs?

A

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

10
Q

why are there no ATCALS equipment AFCQCCs?

A

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

11
Q

What are AFCSIs?

A

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.

12
Q

What are the three main functions of grounding?

A

personnel safety, equipment protection, and noise reduction.

13
Q

What are the four subsystems of the facility ground system?

A

the earth electrode subsystem, lightning protection subsystem, fault protection subsystem, and the signal reference subsystem.

14
Q

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

A

the fault protection subsystem

15
Q

what is bonding?

A

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

16
Q

what does the term bond refer to?

A

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

17
Q

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

A

it should not exceed a resistance of 1 milliohm

18
Q

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

A

soft solder

19
Q

what are the two standards for shielding effectiveness?

A

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.

20
Q

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

A

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.

21
Q

What is considered red equipment?

A

equipment that processes clear-text classified information

22
Q

What is considered black equipment?

A

equipment that processes encrypted or unclassified information.

23
Q

what are the two categories of batteries?

A

primary and secondary cells

24
Q

What is another name for primary cell batteries?

A

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

25
Q

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

A

alkaline

26
Q

What secondary cell battery is known for its lightweight, high power capacity, no memory effect and long shelf life?

A

lithium battery

27
Q

what is the primary reason for an UPS?

A

to provide an alternate source of clean AC power in an emergency.

28
Q

What are the five basic categories of power line faults?

A

sags, blackouts, spikes, surges, and noise

29
Q

what power lines fault is analogous to a tidal wave and can damage or completely destroy components?

A

a spike.

30
Q

What are the three types of UPS defined by the IEC?

A

passive standby, line interactive, and double conversion.

31
Q

What uPS topology has been traditionally referred to as ‘offline’?

A

passive standby

32
Q

What UPS topology has been traditionally referred to as ‘online’?

A

double conversion

33
Q

how many phases are preferred in a generator set for motors and industrial settings?

A

three phase power

34
Q

What are the power specification outputs for the two types of generator sets?

A

three phase generators are set up to produce 120/208 or 277/480 volts. single phase sets are 120 or 120/240

35
Q

what is the purpose of an ATS?

A

It allows for smooth and immediate transfer of electrical current between multiple sources and the load.
