Answer 17

Tone Generator

Question 18

_ is used to trace the tone
Once the cable has been identified, it will play the tone
Each cable end must be probed individually
Also used to identify continuity in a cable

Answer 18

Probe

Question 19

_ is a device used to test cable connectivity

Eg. Can identify missing pins or break in cables

Answer 19

cable tester

cable testers

Question 23

_ is 
o	Also referred to as loopback adapter
o	Device used to test ports
	Serial
	Parallel
	USB 
	Network
o	Device made using
	RJ-45 connector
	Crimping device
	Unshielded twisted pair (UTP) cable
o	Not a crossover cable
o	Device is classified as both male and female because it serves both purposes of transmitting and receiving 
o	Identifies network and network interface card (NIC) issues
	Very low cost
o	Typically uses software to send and receive data to validate the port

Answer 23

Loopback plug

Question 24

_ is
o Also referred to as a krone tool
o Hand tool used to connect network cables to
 Patch panels (a centralized location where all of those wall jacks come together)
 Punch down blocks
 Keystone modules
• (wall jack)
 Surface mount boxes
o Preparing the cable
 Remove the cable jacket to expose a few inches of the wires
 Fan out the cable pairs
 Straighten the ends and place the wires in the jack
• Wires should extend out the jack
o Terminating the wires
 Press down on the wires with the punch down tool, which will also cut any excess wire
 Ensure the punch is not performed on an angle
 Tool should make a clicking sound
o Inspecting the wires
 Inspect each wire to ensure there is no overhang
 Wires should be securely in place
 Trim any wires that remain sticking out using a wire cutter

Answer 24

Punch Down Tool
