Basic Structures Cabling Network |
Telecommunications room Horizontal cabling Work Area |
|
|
Run |
A single piece of cabling. |
|
|
Solid Core |
Each wire in solid core UTP uses a single solid wire. This is a better conductor, but it is stiff and will break if handled too often or too roughly. *Horizontal cabling should always be solid core.* |
|
|
Stranded Core |
Each wire is actually a bundle of tiny wire strands. Not quite as good a conductor, but it will stand up to substantial handling without breaking. |
|
|
The Telecommunications Room |
The heart of the basic star.Where all the horizontal runs from all the work areas come together. |
|
|
Equipment Racks |
Provide a safe, stable platform for all the different hardware components. 19 inches wide, but they vary in height from two-to-three- foot- high models that bolt into a wall to the floor-to-ceiling model. |
|
|
U |
1.75inches =1 U 3.5 inches = 2U 7 Inch = 4 U |
|
|
Patch Panel |
A box with a row of female connectors (ports) in the front and permanent connections in the back to which you connect horizontal cables. They prevent the horizontal cabling from being moved, and are your first defense in the organizing the cables.The most common type is the 110 block. |
|
|
Patch Cables |
Once you have installed the patch panel, you need to connect the ports to the switch through patch cables. They're stranded UTP, so they can tolerate much more handling. |
|
|
The Work Area |
A wall outlet that serves as the termination point for horizontal network cables: a convenient insertion port for a PC and a telephone. |
|
|
Demarc |
Connections from the outside world - whether network or telephone - come into a building at a location called a demarc, short for demarcation point. In a private home, the modem is a network interface unit that serves as a demarc between your home network, and your ISP. |
|
|
Smart Jacks |
Enables the ISP to determine if the customer has disconnected from the NIU. |
|
|
Demarc Extension |
Any cabling that runs from the NIU to whatever box is used by the customer is the demarc extension. |
|
|
Main Distribution Frame (MDF) |
The room that stores the combination of demarc, telephone cross connects, and LAN cross connects. |
|
|
Getting a Floor Plan |
Getting a blueprint is key! The floor plan is the key to proper planning; a good floor plan shows you the location of closets that could serve as telecommunications rooms, alerts you to any firewalls on your way, and gives you a good overall feel for the scope of the job ahead. |
|
|
Mapping The Runs |
Now you run around the work areas, noting the locations of existing or planned systems to determine where to place each cable drop. |
|
|
Cable Drop |
Location where the cable comes out of the wall in the workstatpion. |
|
|
Determining the Location of The Telecommunications Room |
Distance Power Humidity Cooling Access |
|
|
Bonding/Link Aggregation |
The use of multiple NICs for a single machine. Bonding effectively doubles the speed between a machine, and a switch |
|
|
Link Lights |
Tell you that the NIC is connected t a hub or switch. |
|
|
Activity Light |
Turns on when the card detects network traffic, so it intermittently flickers when operating properly. |
|
|
Diagnostics/Repair of Physical Cabling |
Check the LIghts Check the NIC Cable Testing |
|
|
Toner |
Generic term for two separate devices that are used together. The tone generator connects to the cable using alligator clips, tiny hooks, or a network jack, and it sends an electrical signal along the wire at a certain frequency. The tone probe emits a sound when it is placed near a cable connected to the tone generator |
|
|
Attenuation |
As a signal progresses down a piece of wire, it becomes steadily weaker. |
|
|
Cable Certifiers |
The process of verifying that every cable run meets the exacting TIA/EIA standards |
