Wiring Implementation

Question 1

What is a structured cabling scheme?

Answer 1

A standard way of provisioning cabled networking computers in an office building

Question 2

What is the best known cabling scheme?

Answer 2

ANSI/TIA/EIA 568 Commercial Building Telecommunications Wiring Standard.

Question 3

What does ANSI/TIA/EIA 568 identify in a structured cabling system?

Answer 3

Work Area- The space where user equipment is located and connected to the network.

Horizontal Cabling- Connect user work areas to a IDF, typically consists of the cabling for a single floor and is made up of cables that run horizontally through wall ducts or ceiling spaces.

Telecommunications Room- A room that houses IDF and networking equipment, stores only networking equipment and termination point for horizontal cabling.

Backbone Cabling- Connects IDFs to the MDF, referred to as vertical cabling because it is likely to run up and down between floors

Entrance Facilities/Demarc- Special type of telecommunications room marking the point at which external cabling is joined to internal cabling, via the MDF.

Question 6

What is IDC?

Answer 6

Insulation displacement connection.
A block used to terminate twisted pair cabling at a wall plate or patch panel.

Question 7

What is a MDF?

Answer 7

Main Distribution Frame.
The prime hub for all the network cables in the building.
Should be in a secure area.

Question 8

What is a IDF?

Answer 8

Intermediate Distribution Frame.
Connects to the MDF
Extends network access from the MDF to other locations like different floors or separate buildings.

Question 9

What is a service loop and what is its purpose?

Answer 9

It is a extra length of cable at both ends of a cable run and it allows for adjustments, reconnections or changes in the future without needing to install new cabling.

Question 10

What are requirements for horizonal cabling in a structured cabling scheme?

Answer 10

If using copper cabling must be within 90m (295ft) cabling distance of each wall port.
Connects user work areas to IDF.
