CCT5 (Nationals) Flashcards
Group of computers that communicate as if they were attached to the same wire, regardless of their physicallocation.
VLAN (Virtual Local Area Network)
When a groups of users need to be on the same broadcast domain because they are running the same applications, what can a customer’s IT vendor implement?
VLAN (Virtual Local Area Network)
Ingress from transmitters operating in the upstream frequency bandwidth with the majority of ingress entering the system between the tap and the customer’s TV set.
Return Path Interference
This cable shall be used in vertical shafts and from floor to floor in multistory buildings.
CATVR (Riser)
This is caused in one channel by the carrier from another transmitter operating on the same channel.
Co-channel Interference
A detailed, thorough analysis of all ofthe features currently existing at a customer site.
Site Survey
A support mechanism used to route and support telecommunications cable or power cable. Typically, these are equipped with sides that allow cables to be placed within the sides over its entire length.
Cable Trays
This multicast RF translation table handles all of the entitlement control and management messages such as the ability to such as the ability to receive a subscriber only channel such as HBO.
CAT (Conditional Access Table)
Cable and connecting hardware that interconnectsbetween telecommunications rooms,equipment rooms, and entrance facilities.
Backbone Cable
For building with exteriors like brick, shingles, stucco, and tile, try to drill carefully from:
Outside to Inside
A tubular rigid or flexible metallicor non-metallic raceway through whichcables can be pulled.
Conduit
A chemical change caused by a reaction to oxygen such as rust.
Oxidation
This is a custom Ethernet Network that allows customers to seamlessly link multiple locations together and exchange data up to 1Gb per second.
ENS (Ethernet Network Service)
Any enclosed channel designedfor holding wires or cables.
Raceway
A large business is any business with greater than how many users?
50 users
Has the same attributes as a physical LAN, but allows for computers to be grouped together even if they are notlocated on the same LAN.
VLAN (Virtual Local Area Network)
This compensates for cable non-linearity
Equalizer
A device that provides hotel management with the ability to monitor the network and directs the user to the hotel’s designated first page/splash screen.
IP3 Net Server
The vertical and horizontal route of the telecommunications cable.
Pathway
A designated area used for transport ofenvironmental air as part of the air distribution system.Because it is part of the air distribution system, cablesinstalled in this space require a higher fire rating.
Plenum
What are the four types of maps used in cable network design?
- Base Map2. Strand Map3. Design Map4. Amplifier Schematics or Tree Maps
In general, if the building has wooden exterior siding, you will drill from:
Inside to Outside
This type of map resembles a street map, complete with features like lakes and rivers, streets, and boundaries.
Base Map
This Status sub menu under Status in a Vecima Networks Web Interface will show the interface information for the device as well as how it’s processing the RF.
eCMM Status
Wire management ring made of metal or plastic, and shaped like the letter D for routing and supporting distribution cables and/or cross-connections on a backboard.
D-Ring
This status page in a Q2Q Vecima Networks Web Interface displays current and historical alarms
Alarms
This is installed in each guest room to convert the coaxial signal back to Ethernet over CAT5. It also provides a connector for the coaxial cable thatruns to the television.
MPO (MegaPort Outlet)
If a channel map change is being made on a MDTA such as a VCT_ID or muting/inserting channels, it is only necessary to perform which Reboot in the Vecima Networks Web Interface?
Reboot MDTA
This type of map also includes symbols indicating the other service companies using a pole, such as the power company, the telephone company, or both.
Strand Map
Cable that runs from the telecommunications room to a device. It may be installed in either a horizontal or vertical plane.
Horizontal Cable
At any temperature above absolute zero, this is caused by random electron activity of the atoms that make up the conductor, resistor, or any part of the passive circuit in question.
Thermal Noise
Why not just subnet the network instead of using VLAN’s?
With a VLAN, devices in different physical locations can be on the same local area network.
A panel (e.g., wood or metal)used for mounting connecting hardware andequipment.
Backboard
Another source of interference that affects the return path, but is not ingress related, is ___..
Common Path Distortion (CPD)
Cable that is run in the plenum spaces ofbuildings.
Plenum Cable
