DSL Broadband

What is DSL broadband ?
Simply put, broadband is a high-speed connection to the Internet that is always on. Broadband is faster than a standard dial-up, enabling you to view web content faster and download files more quickly. Besides being faster, broadband is more reliable than dial-up, due to broadband’s digital nature and ‘always on’ connectivity. With broadband, when you turn on your computer, you’re already connected to the Internet and ready to surf at high speeds.
 
How fast is DSL?
The short answer is “it depends”. Typically speeds start at about 128Kb/s and go up to 1.5Mb/s for most home users. Some installations may go as fast as 50Mb/s or more depending primarily on the equipment used, distances involved, cabling quality, encoding techniques, frequency spectrum available and even to some degree, end system configurations. Speeds can vary from provider to provider even if they are all servicing your area from the same central office.
How does the DSL technology work?
DSL stands for Digital Subscriber Line – a technology which transforms plain old telephone lines into a high speed conduit for data, information, entertainment and more. It utilizes more of the bandwidth on copper phone lines than what is currently used for plain old telephone service. The DSL technology uses the frequencies above the telephone bandwidth. Therefore on different frequencies one can be on voice and on the Internet simultaneously.
 
What is Upstream and Downstream bandwidth?
Upstream refers to the bandwidth for traffic from the end user PC to the Internet while downstream refers to the bandwidth for traffic from internet to the end user. For Internet surfing, the downstream traffic is much more than upstream traffic.
 
What is Symmetric/Asymmetric DSL?
Symmetric DSL refers to DSL technologies which provide the same bandwidth upstream and downstream. E.g. like HDSL (High Bit Rate DSL), IDSL (ISDN DSL). Asymmetric DSL refers to DSL technologies, which provide higher downstream bandwidth with lower upstream bandwidth. E.g. ADSL.
 
Why should I consider getting DSL broadband?
For the sheer speed and power that makes communication easier than ever before and helps you make the most of everything the Internet has to offer.
 
If that’s not reason enough, here are some more:
  • Very fast connection. DSL delivers Internet easily when you need it.
  • Always ON. No call charges for just getting connected.
  • Be able to use the phone for voice calls while surfing, no need to go for additional connection for Internet
How expensive is DSL?
It depends on your needs, usage and the kind of solution you go in for. You can get a DSL connection for as low as Rs 300. Choose from a variety of Tariff plans to suite your needs.
 
What is an “always on” connection?
Basically, the single-click Airtel Broadband Services ensures fast connectivity, so the Internet is on and ready when you need it.
Airtel Broadband Services enables you to establish a dedicated connection between your computer at your home or business location and our Network. This connection can be established with a simple click of the mouse and only takes 1-2 seconds, so there is no more waiting while your computer gets connected to our network. Unlike ‘Dial Up’ where often you can get a busy tone, and not get connected, DSL connection is assured.
How do I secure my systems from Internet attacks?
Inherently, you are no more at risk with DSL service than any other connection to the Internet, whether it be dial-up, cable modem or otherwise. However, you are probably more likely to be attacked due to the amount of the capacity you may have or due to the fact that you’re always connected to the net.
First and foremost, you must ensure that your end host(s) is/are secure by applying the latest patches to the OS and services you run. It is also highly recommended that you disable any services that you do not really need (e.g. web server, ftp server, port 139 on Windows machines, and so on). Although it is beyond on the scope of this FAQ to describe the process of securing your host, it is of utmost importance to leave few doors and windows open into your systems. You can use firewall toolkits and filtering software to help control access to your systems, but understand that they are limited as a network solution to a host problem. Email Trojans for example can bypass most firewalls.
 
How do I tune my DSL line for maximum performance?
There is little you can do to really tune your DSL line. You’re generally relying on the cabling plant installed in your house all the way through to the provider’s network. Since many types of DSL service can run over what is jokingly referred to as CAT-0 cable, your speed is typically determined at provisioning time. If you are rewiring your home, it of course does make sense to perform a high quality wiring installation.
How does DSL work on my existing phone line?
DSL is really a feature added to your existing phone line.
Data signals and voice signals travel at different frequencies. The DSL splitter segregates the two signals to put the voice calls on to the telephone, and the data traffic on to the PC through the DSL modem
 
What does a POTS splitter do and when do I need one?
Splitter helps to separate the voice signals from the data signals. It is a passive device, which does not require power, so that the “life-line” voice service can be provided, as has been in the past
 
Does DSL require a UPS in case of a power failure?
There are two types of CPEs, one which need a power supply and one which does not. One which requires a power supply needs a UPS connection, the other of course needs no power supply.
