2.8 Given a scenario, use networking tools

Question 1

“Pinch” the connector onto a wire
–Coaxial, twisted pair, fiber
* Connect the modular connector to
the Ethernet cable
–The final step of the process
* Metal prongs are pushed through the insulation
–The plug is also permanently pressed
onto the cable sheath.

Answer 1

crimper

Question 2

Used to remove the outer coverings of the cable to get to the wire pairs within. Place the end of the cable in the mouth of the device close the mouth and circle the cable cutting away the outer sheath without damaging the wire pairs within.

Answer 2

Cable Stripper

Question 3

• Purpose-built hardware or
  mobile device add-on– Specializes in 802.11 analysis
• Identify errors and interference– Validate antenna location and installation.

Answer 3

WiFi analyzer

Question 4

Consists of two parts. A generator and a probe. Sends a tone that goes to the end of a cable that receives the signal. Generates a signal that is transmitted on the wire you are attempting to locate.

Answer 4

Toner probe

Question 5

Punch” a wire into a wiring block– 66 block, 110 block, and others
* Can be tedious– Every wire must be
individually punched.
* Trims the wires during the punch.

Answer 5

Punch-down tool

Question 6

• Relatively simple– Continuity test
• Can identify missing pins– Or crossed wires
• Not usually used for frequency testing. Crosstalk, signal testing, ETC

Answer 6

Cable Testers

Question 7

• Useful for testing physical ports– Or fooling your applications
• Serial / RS-232 (9 pin or 25 pin)
• Network connections– Ethernet, T1, Fiber
• These are not cross-over cables
  They take the singal going out and echo it back.

Answer 7

Loopback plugs

Question 8

Intercept network traffic– Send a copy to a packet capture device. Consists of three ports, An input port, and output port, and a monitor port.

Answer 8

Network Tap
