Week 5 Broadband Connections Flashcards
Broadband
Any connectivity technology that isn’t dial up internet
T-carrier technologies
Originally invented by AT&T in order to transmit multiple phone calls over a single link
T-1
Twisted pair copper connection or Transmission System 1
T3
Has 28 T1
Digital Subscriber Line (DSL)
A frequency range that didn’t interfere with normal phone calls
Digital subscriber line access multiplexers (DSLAMs)
Are like modems for DSL
What are the 2 most common DSL?
ADSL
SDSL
Asymmetric Digital Subscriber Line (ADSL)
Connection feature different speeds for outbound and incoming data.
(Faster download speed and slower upload speed)
Symmetric Digital Subscriber Line (SDSL)
Upload and download speed are the same
SDSL upper cap is:
1.544 megabits a second the same as T1
The connection from your home or business goes to:
Central office or CO
Cable modem
A device that sits at the edge of a consumer’s network and connects it to the cable modem termination system or CMTS
FTTX stands for
Fiber to the x
FTTN stands for
Fiber to the neighborhood
FTTB (fiber to the building)
Used for data delivery to an individual building
FTTH (fiber to the home)
Each individual neighborhood or apartment building
FTTP
Fiber to the premise
Optical Network Terminator (ONT)
Converts data from protocols the fiber network can understand, to those that more traditional, twisted pair copper networks can understand
Point to point protocol (PPP)
Encapsulates data, so any PPP configured devices can communicate without issue
Point to point over Ethernet (PPPoE)
Extra layer of encapsulation for standard PPP frames, to enable data to be sent over Ethernet connections
Cable internet has:
Broadband connections
Shared bandwidth connections
Sub protocol for PPP
Network control protocol(NCP)
Link control protocol (LCP)
What is the demarcation point for fiber technologies?
ONT
