ADSL

Q2-How does ADSL works ?
Ans-ADSL uses standard telephone lines to upload and download data on a digital frequency, which sets these datastreams apart from the analog signals that telephones and fax machines use. The telephone can be used at the same time when surfing the Web with DSL service because the signal is operating on a different frequency; this is not true of conventional dial-up Internet access.

Q3-What is the availability of ADSL ?
Ans-ADSL is not accessible to all communities, and coverage is often especially spotty in rural areas.

Q4-What is DSL ?
AnsDSL (digital subscriber line) technologies, often grouped under the term DSL, connect a computer to the Internet. DSL uses existing copper pair phone line wiring in conjunction with special hardware on the switch and user ends of the line. This special hardware allows for a continuous digital connection over the phone lines.

Q6-What is the mode of communication of ADSL ?
Ans– ADSL communication is full-duplex.Full-duplex ADSL communication is usually achieved on a wire pair by frequency-division duplex (FDD).

Q7-What happens to an existing line when we upgrade to ADSL ?
Ans-ADSL is an upgrade to our existing analogue phone line; it can also technically be an upgrade to an ISDN line, but that is not currently offered by BT or ISPs in the UK. Our existing analogue (voice) line will operate as before, including BT ‘Select Services’ such as Call Waiting, Caller Display and Call Minder. You will not see any physical change to the line for a new ADSL conversion.

Q8-How does ADSL differ from ISDN in functionality ?
Ans-Both ADSL and ISDN use a copper pair of wires between you and the local exchange.An ADSL line provides a normal analog phone service, plus the digital service. An ISDN line provides only a digital service, but that can be ‘converted’ to analog by your terminal equipment or Highway wallbox for voice calls.

Q9-How does ADSL compare to ‘Cable modems’ ?
Ans-A Cable Modem will give you high speed data access to the Internet. One major physical difference between ADSL and Cable is that with ADSL, your data is carried down your own copper pair (wire) all the way to the BT exchange. In the case of cable modems, you share a common ‘bus’ with your neighbours back to the head-end router in the cabinet at the end of your street.

Q10-What does an ADSL line connect to ?
AnsADSL LINE
