Question 1

Cable Crimpers

Answer 1

-Pinch the connector onto the wire

• Connect the modular connector to Ethernet cable
  
  • Final step of process
• Metal prongs are pushed through insolation
  
  • Plugs are permanently pressed onto cable jacket

Question 2

Multimeter

Answer 2

• AC Voltage
  
  • Check wall outlet voltage
• DC Voltage
  
  • PC power supply output voltages
  • CMOS battery power
• Continuity
  
  • Cable connectivity ; fuse stats ; wire mapping

Question 3

Toner Probe

Answer 3

• Where does it go (wire)
  
  • Follow the tone
• Tone Generator
  
  • Puts an analog sound on the wire

Inductive probe

 - Doesn't need to touch copper
 - Hear through a small speaker

Question 4

Cable Tester

Answer 4

• Relatively Simple
  
  • Continuity test

-Can identify missing pins or crossed wires

• Not usually used for frequency testing
  
  • Crosstalk , signal loss , etc.

Question 5

Loopback Plugs

Answer 5

• Useful for testing physical ports
  
  • Or fooling your application
• Serial / RS - 232 (9 pin or 25 pin)
• Network Connection (Ethernet , T1 , Fiber)
• They are not crossover cables

Question 6

Punch-down Tool

Answer 6

• Punch a wire into a wiring block
  
  • 66 block
  • 110 block
• Can be tedious ( Everything wire individually punched)
• Trim the wires during the process (very efficient)

Question 7

Wireless Analysis

Answer 7

• Wireless network are the easiest to monitor
  
  • Everything “hears” everything
• Purpose-built hardware or mobile device add-on
  
  • Specializes 802.11 analysis

-Identify errors & interference
