BSNL Broadband


What is a firewall, should I have one?

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.

Do ADSL services come with a service level agreement ?

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.

What is NAT (Network Address Translation/Translator)?

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.

Can I host a web server on an ADSL line ?

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.

I have ADSL at office, can I also use it at home ?

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.

And one thing, that month i used net very frequently.So, my doubt is eventhough if do not downloaded anything i exceeded my limit. What would be the correct reason for this?

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.
