Krone block

110 block

66 block

3. Which punchdown block is more often used with telephones (Cat 3)?

Bix block

Krone block

110 block

The color code for T568B jacks

The author of EIA/TIA 568

None of the above

5. What actually makes the electrical connection with the wires in a 110 block?

Punchdown tool with 110 blade

Insulation displacement connectors in the connecting block

The base of the block

Make sure to not nick the wires

Strip the wires individually

Retwist any pairs that come untwisted

Note the distance markings on the cable

Mark the cable for documenting its location later

Pull the cable gently from the box

Do not untwist the pairs more than 1/2 inch (12 mm)

8. Why does each pair in Cat 5/5E/6 cable have different twist rates?

Help identify each pair

Decrease signal attenuation

Equalize NVP

Prevent crosstalk

9. The punchdown tool does two jobs. What are they?

Pushes the wire into the IDC contact

Untwists excess wire

Makes the installation neater

Cuts off the excess wire

The connector used only with Cat 5 jacks

A special high frequency connector

A modular 8 pin connector with USOC termination

A trade name
