TDMM Chapter 10 Flashcards
Administration
The methodology defining the documentation requirements of a cabling system
AIM

Hardware/Software system that documents, monitors and automates the management of information technology
Cable Labeling System
A scheme employed when identifying communications cable or its associated hardware
Identifier
An item of information that links a specific element of the telecom infrastructure with its corresponding record
Labeling System
A methodology which allows unique identifiers to be assigned to all elements of an ICT infrastructure
RFID
Radio Frequency Identification
Technology that uses radio waves to automatically identify people of objects

True
True or False
All patch panels have manufacturer provided label fields
False
What type of information is helpful to include when labeling the backbone cabling between distributors?

What factors are used to determine the choice of material and fastening method for displaying identifiers in a telecom cabling infrastructure?
Environmental, performance and security issues
True or False
Handwritten labels shall be used to ensure labeling can be performed quickly and easily
False
Machine written only
Name three common methods of displaying identifiers, bar codes and graphics
- Labels
- Tags
- Electronic Identifiers
Name the two parts of a typical label
- Label face
- Adhesive material
What is the most common method for identifying cabling pathways, spaces, equipment and components
Adhesive labels
Name two factors to consider when selecting the material for a label
- Label environment
- Expected label life cycle
Name four major metrics for selectring appropriate labels for an administrative system
- Application
- Durability
- Environmental
- Security
Name four environmental metrics to consider when selecting the appropriate labels for an administrative system
- UV rating
- Temperature rating
- Moisture resistance
- Service exposure
Name three security metrics to consider when selecting the appropriate labels for an administrative system

- Tamper resistance
Name the four metrics used to quantify label performance
- Visual inspection
- Rub test
- Scrape test
- Adhesion test
How does a tag differ from a label?
A tag is often only partially attached to the mounting surface and a label is fully attached
How can tags be fastened to telecom equipment?
- Adhesive
- Cable ties
- Strings
- Other methods
What is the most common method of tagging components electronically?
RFID

- Room number
How are conduits marked in a basic system?
By painting or using colored tape wrap
What information should be included on the label for a zone box?
- Room of origin
- System usage
What information should be included in the label for an equipment grounding conductor?
- Grounded component
- Ground bar to which the grounding conductor is connected
How is active equipment typically identified?
By the network hostname

What are some examples of the types of documents that might be included in campus records?
- Drawings and diagrams of network
- Maps, location records, cable records
Name three methods for identifying floor plan locations for equipment
- Use of access floor tile grids
- Use of ceiling tile grid in rooms without access floors
- Application of a grid to the floor plan if no floor or ceiling tile grid
