|
Individual collision domains
point to point full bandwidth dedicated bandwidth for each port |
|
|
When planning the installation of LAN cabling, there are four physical areas to consider:
|
Work area
Telecommunications room, also known as the distribution facility Backbone cabling, also known as vertical cabling Distribution cabling, also known as horizontal cabling |
|
|
What is horizontal cabling and backbone cabling?
|
Horizontal cabling refers to the cables connecting the telecommunication rooms with the work areas.Backbone cabling refers to the cabling used to connect the telecommunication rooms to the equipment rooms, where the servers are often located.
|
|
|
For UTP installations, the ANSI/TIA/EIA-568-B standard specifies that the total combined length of cable spanning three of the areas listed above, excluding the backbone cable, is limited to a maximum distance of
|
100m per channel
|
|
|
his standard also specifies maximum backbone distances, ranging from
|
90m for UTP to 3000m for single mode fiber cable
|
|
|
What types of UTP interfaces are there?
|
MDI (media-dependent interface)
MDIX (media-dependent interface, crossover) |
|
|
Wide area connections between networks take a number of forms, including:
|
Telephone line RJ11 connectors for dialup or Digital Subscriber Line (DSL) connections
60 pin Serial connections |
|
|
To connect a Cisco router to WAN, what type of connectors are used?
|
Winchester 15 Pin connector and male DB-60 connector or a Smart Serial connector
|
|
|
What terms describe the types of devices that maintain the link between a sending and a receiving device?
|
Data Communications Equipment (DCE) - A device that supplies the clocking services to another device. Typically, this device is at the WAN access provider end of the link.
Data Terminal Equipment (DTE) - A device that receives clocking services from another device and adjusts accordingly. Typically, this device is at the WAN customer or user end of the link. |
|
|
LAN Interfaces - Ethernet
|
The Ethernet interface is used for connecting cables that terminate with LAN devices such as computers and switches. This interface can also be used to connect routers to each other.
|
|
|
WAN Interfaces - Serial
|
Serial WAN interfaces are used for connecting WAN devices to the CSU/DSU. A CSU/DSU is a device used to make the physical connection between data networks and WAN provider's circuits.
|
|
|
Console Interface
|
The console interface is the primary interface for initial configuration of a Cisco router or switch.
|
|
|
Auxiliary (AUX) Interface
|
This interface is used for remote management of the router.
|
|
|
To connect to a router or switch for device management using terminal emulation, follow these steps:
|
Connect a computer to the console port
configure a terminal emulator with the proper settings. Log in to the router using the terminal emulator software. |
