Broadband refers to a connection that has capacity to transmit large amount of data at high speed. Presently a connection having download speeds of 256 kbps or more is classified as broadband. When connected to the Internet such a connection allows surfing or downloading much faster than a dial-up or any other narrowband connections. BSNL offers 2 Mbps minimum download speed for its Broadband connections. |
| |
ADSL stands for Asymmetric Digital Subscriber Line. It is a technology that allows copper telephone pairs to be used to provide a broadband connection. It provides ‘always-on’ Internet connection that is automatically established once the PC and ADSL modem are switched on. |
| |
Always-on means that the ADSL broadband sets up a permanent connection to the internet that lets you access the internet as soon as you switch on the computer and the modem. You do not need to dial up like when you are using a standard modem connection. There will be no call charges for Internet access but voice calls will be charged as before. |
| |
If you are using a 2 Mbps broadband connection then you will be having a download speed which is 35 times faster than that of normal dial-up connection, about 16 times faster than that of ISDN connection and about 16 times faster than that of DIAS connection. |
| |
o Fast downloads
o Upto 140 times faster than dial-up connection
o Always on connection
o Telephone and Internet access can be used together
o No telephone call charges
o Cost effective way to access Internet
o A host of free content on the web can be downloaded faster
|
| |
Both of these connections offer high speed Internet access respectively for home and office environment. In BSNL Broadband for business connecting more than one computer may be allowed along with other features like extra email addresses, domain name, web hosting space , static IP (Select Plans only) etc.
|
| |
No. ADSL can run on your existing basic phone (Bfone) line. If you do not have a Bfone connection then you need to get one from BSNL before you can ask for an ADSL broadband connection.
|
| |
Yes. ADSL uses a different set of frequencies and does not interfere with telephone conversation. Conversely, making a phone call while accessing the Internet does not affect the speed of the ADSL connection.

CPE stands for Customer Premise Equipment. This consists of an ADSL modem/router and a stand-alone or a build in splitter to separate the telephone and broadband connections. There are three options for getting the CPE from BSNL. Option I - Free Modem (Available only With selected Plans subject to conditions). Option II - Outright Purchase from BSNL. Option III - On Rent. Please click here for details |
| |
If at your home/business, the same line is used for voice and data then you need to separate out these signals by using a splitter. The splitter will have one output for your telephone and one or more for the ADSL modem which in turn connects to your computer. This comes along with the modem that BSNL provides. |
| |
These could be the reasons for this. Your distance from the nearest ADSL Central Office equipment(DSLAM) may be beyond the technically permissible limit. Visibly the distance of your house/business may look same to you as your friend's but it is the actual cable length that counts. Once you apply for a BSNL broadband connection, you line will be tested and you will be informed whether you home/business is covered.
Other reason could be that your friend has a BSNL fixed line phone and you do not.

When the information flows from somewhere e.g. a web-page or a site to your PC you are “downloading” on the other hand when you send information e.g. request for a web-page, you are “uploading” |
| |
ADSL is an asymmetric technology giving different rates in “down” and “up” directions. This is perfectly fine since we download(browsing, downloading clips, music etc) much more than we upload(a website address, a few clicks etc) |
| |
To connect to ADSL you need an ADSL modem/router to be installed at your home/business. On your PC you should have an Ethernet port with RJ45 socket. Some ADSL modems have a USB port and you could connect these modems to the USB port of you computer. |
| |
Once your connection comes through, an installation pack consisting of the CPE and installation guide will be sent to you. If you have requested BSNL for installation, a technician will visit and complete the installation for you. If you are buying your own Modem you can still request for installation on payment of the requisite charges. We will, however, only support equipment supplied by us.
|
| |
Once we receive your order, BSNL will do the required line checks and assuming these pass it takes around 5-10 working days for the service to be enabled by BSNL at your local telephone exchange. |
| |
No. With your Welcome Pack you get an installation CD which includes everything you need to get started. If you choose to use your own equipment (e.g. modem or router) then you will need to ensure you have the right software. |
| |
When you are connect to the Internet, your PC is automatically allocated an IP(Internet Protocol) address to identify it to the outside world. There are two types of IP addresses, dynamic and static. Dynamic IP changes from session to session while static always remains same.
|
| |
IP addresses could be dynamic (that typically change with each session) and static (that are permanently allocated to you). BSNL Broadband provides both dynamic and static IP. However the static IP is given only in Business 5000 and Business 9000 plans. |
| |
A static IP address may be required for certain services or applications you use. These typically include:
1.Running your own mailserver (SMTP inbound).
2.Many VPN (virtual private network) implementations require one or both sides of the VPN to have a static IP address.
3.If you are connecting to your company network and need access through their firewall.
|
| |
Yes, You can change your BSNL Broadband plan at any time. |
| |
ADSL connection is given for a particular BSNL fixed line. If you move, ADSL can be shifted to a BSNL line in the new location subject to availability in that area. No shifting charges are required to be paid.
|
| |
Yes. The ADSL broadband service uses your normal analogue exchange line to provide the high speed Internet access, so you still need to pay the line rental and any normal calls on that line. |
| |
This will depend on the purpose for which you will be using the broadband connection. If you are using it from home or a small office, choosing a plan that offers a download limit of 1 GB is ideal for general surfing and emailing. However, if you are downloading lots of videos or sending very large files, it may be better to choose a broadband plan with even higher capacity. |
| |
Broadband from BSNL is charged monthly, via your BSNL bill. You can choose to pay your BSNL bill by cash, cheque or bank or credit card. |
| |
No. The helpdesk is there to help you with problems relating specifically to the Broadband service from BSNL and the hardware/software provided by BSNL. If you have purchased a product where hardware was not provided as part of the service, the helpdesk will not be able to assist you with it, and you should contact your hardware supplier. |
| |
You can have more than one line, however we cannot guarantee service on broadband connections, therefore we do not suggest an additional broadband line for redundancy/up-time. |
| |
No, you will be able to use the modem/router provided with your current Broadband |
| |
Yes, if you choose the right broadband plan, you would be permitted to connect more than one computer. However, all the users will share the bandwidth allocated to you. |
| |
To provide a cost effective service - all ADSL services are contended (shared). These contention ratios are applied in the backbone and international part of the network. A commonly applied contention
rate is 50 : 1.
All customers are guaranteed the plan rate up to the local exchange or the ADSL equipment to which they are connected. On the shared part of the network a 50:1 contention ratio would mean that a 2 Mbps connection would be shared by 49 others. In reality this is very unlikely to happen and the customer would find the connection much faster than dial-up modems. ADSL relies on individual users not making unreasonable traffic demands on the network to provide fast access speeds for all. If you are not getting the speed you expect, it can be due to the contention ratio but also to many other factors including the congestion at the remote site you are accessing.

BNSL aims to provide fast, reliable service to all the broadband customers. Some customers try to hog disproportionate amount of available resources. Customers might select lower end plans for heavy work or make excessive use of peer-to-peer file sharing. This could result in 20% users using over 80% resources. High levels of usage by a small number of users risks reduced performance for all users. BSNL has the following options to solve this problem :
1. Lower the contention ratio
2. Provide more resources and increase the prices
3. Set download limits
The first two options are not fair to 80% users who use the resources sensibly. As such setting dowonload limits was the best and fair solution. If any user requires higher limit he/she can upgrade to higher plan.

One GB is 1024 Megabyte or 1073741824 bytes. You can do the following with 1 GB download limit :
1. An average web page is about 50 kilobytes in size - so you could
download around 20,000 web pages for 1 gigabyte.
2. An hour of surfing the web would be around 10 megabytes (200 pages)
so you could surf non-stop for about 100 hours for 1 gigabyte.
3. An hour of streamed radio would use about 15-20 megabytes.
4. An hour of streamed video uses around 100-150 megabytes.
5. Playing an online game typically uses about 10-15 megabytes per hour.
6. Emails are very small - so 100 emails would be just 1 megabyte - or 100,000 emails for 1 gigabyte! (of course the attachments count extra)
7. A super-high resolution (5-6 megapixel) digital camera JPEG picture or typical MP3 music file is about 2-3 megabytes so you could download 350-500 of these images/music files for 1 gigabyte.
Very few users would actually exceed the download limits set.

A firewall is a system designed to prevent unauthorized access to or from a private computer/network. It is highly recommended that all Internet users (even using standard dialup access ) should have a firewall to protect their computer/network. As ADSL broadband service are ?always on? it is even more important. Many free firewall softwares like ZoneAlarm, Sygate Personal Firewall etc are available on the Web for download. |
| |
ADSL broadband services do not come with a SLA (service level agreement). However BSNL aims at repairing 80% of ADSL circuit faults within working hours. If you require a ‘guaranteed’ high-speed connection to the Internet you would probably require a leased line instead of ADSL broadband. |
| |
NAT stands for Network Address Translation/Network Address Translator. Each computer connected to the Internet needs to have a unique IP address. To use the global IP addresses more efficiently, computers belonging to a business can have “local” addresses. NAT would then allow connecting multiple “local” computers to the Internet using one IP address. Each NAT has a ‘table’ of local IP addresses and globally unique addresses by which the NAT box can translate the local IP addresses to global address and vice versa. |
| |
A web server can be hosted on an ADSL line with static IP addresses for broadband connection. (Static IP addresses are available in Business 5000 and Business 9000 plans) Although it is technically possible but not recommended specially for important or heavy usage service. ADSL is asymmetric service with upstream rates much lower than downstream rates. In the business plan upstream rate is 128 kbps and with usual contention ratio, performance can be poor if many users try to access the web server. As it is not a recommended use, BSNL would not support maintenance complaints in such cases. |
| |
An ADSL Broadband account is activated on a specific telephone line only. If you need to use the broadband connection at a location other than where it is installed you need to take another broadband connection. |
| |
You can call 24 hours helpline number:
1600 424 1600 |
| |
Most present day configuration PCs will run ADSL. The following minimum configuration is, however, recommended:
Processor 200 MHz (or better)
Operating System Windows 98SE (or higher)
RAM (memory) 32 MB RAM
Free Disk Space 125MB
SVGA monitor
CD-ROM Drive
Network Interface Card(NIC) with 10/100 Mbps Ethernet port with RJ45 socket

In broadband connection it is different from dialup connection. Here frequency doesnot matter as it is always on conncetion. What matters is the size of the pages you visit. If you visit sites which are having small graphics and more text then you are downloading very small amount of data. But if you are visitng sites with large graphics or streaming videos then you are downloading higher amount of data. |
| |
For certain plans, the modem shall be given free by BSNL subject to some conditions - (For details click here). In this case customer will own the modem and does not require to return the modem.
Any type of modem (Type I/II/III/IV) can be taken under this offer after paying the required cost/rent of modem.
If a subscriber has initially taken Type-I modem under this offer, he can request to change it to higher type (Type-II/III/IV) after paying the difference amount of higher modem.
After the committed period if a subscriber demands another modem then he can choose any of these three options: (i) He can get another modem by paying the rent for another committed period. or (ii) He can choose rental option for another modem. or (iii) He can outright purchase another modem. |
| |
Option 1: If you want to continue with the existing modem, 50% of the amount already paid as monthly rentals can be adjusted in the Sale Price of modem.
Option 2: If you want a new modem, Full amount will be charged as per Prevailing Price for the new Modem and the Old Modem is to be returned in working condition. |
