BSNL ADSL Complete overview
Broadband – The concept
Few years back, we were introduced to the Internet revolution. Internet has opened up the globe to us and made communication very easy and practical. Internet is mainly used for E-mail, searching information, or E-commerce etc. But still we are far away from the quality of Internet that we can consider excellent.
What does quality mean for a person who is using the Internet?
A person wants trouble free internet access, at an affordable price, which is consistently working for hours together at a satisfactory committed speed without any problems.
These are the basic expectations of users who expect to use internet efficiently.
Presently most of the internet users are using either PSTN (Public Switch Telephone network) connection of 56 Kbps for Internet connectivity or 128 Kbps ISDN connectivity or very few uses above 128 Kbps by way of wireless, or leased line access. High speed Internet connectivity still is not affordable and available everywhere due to lack of proper infrastructure at Service providers end.
Now it is possible to have Internet connectivity at the speed of 256 Kbps and above, which has been termed as “Broadband”.
High speed internet was a luxury for the common man till the launch of this Broadband service. With the launch of Broadband service, things will change as far as data connectivity is concerned. Internet connectivity will be one of the options of this service.
Broadband connectivity can be provided by various means such as ADSL (Asymmetric Digital Subscriber Line), Wireless, Optic fiber, or Cables for television sets. So there are different types of Medias for connectivity.
Every media has its own advantages and limitations.
Wireless technology is suitable in places where copper connectivity is not feasible. Wireless technology is an alternative to wired technology, but as of today, most of the companies don’t have a ready infrastructure for giving wireless connectivity till the last subscriber and secondly the cost per subscriber will be very high at present. In the present situation wireless technology has bandwidth limitation over ADSL2+ technology.
Broadband Connectivity via TV cable can be an alternative to ADSL, but it is unreliable and inconsistent due to delicate nature of the infrastructure.
Optic Fiber technology is definitely superior for broadband connectivity but it is very expensive in making the infrastructure ready till the subscriber who is at the farthermost end from the exchange; and at present nobody has got last mile optic fiber connectivity.
ADSL technology for broadband uses existing telephone copper wire for high speed data communication. User can simultaneously use telephone and Internet. With existing ADSL 2 + downloading up to 24 Mbps is also possible. For users it is sufficient for today’s needs.
Broadband Connectivity Specifications in view of Broadband policy of Government of India
In view the new broadband revolution, Government of India has released the Broadband Policy in October 2004. This policy talks about the framework of broadband connectivity and its specifications. You can read the detailed broadband policy on website of DOT at -
The definition of Broadband connectivity as per the Government of India is:
An ‘always-on’ data connection that is able to support interactive services including Internet access and has the capability of the minimum download speed of 256 kilo bits per second (kbps) to an individual subscriber from the Point Of Presence (POP) of the service provider intending to provide Broadband service where multiple such individual Broadband connections are aggregated and the subscriber is able to access these interactive services including the Internet through this POP. The interactive services will exclude any services for which a separate licence is specifically required, for example, real-time voice transmission, except to the extent that it is presently permitted under ISP licence with Internet Telephony.”
As per this definition BSNL has introduced Broadband using ADSL technology.
As a customer of Broadband, you have a right to know about the meaning of Broadband connectivity. From the above definition it’s very clear that
1. Broadband Connection should be "always ON".
2. The minimum download speed of 256 Kilo bits per second should be available to an individual subscriber from service provider to subscriber end for the Internet and other interactive services.
3. The connection should be able to support Interactive services including Internet access. This also clearly means that, in future, many more services can be offered on this same broadband connectivity.
Regarding this there is one more notification published by Ministry of Communications and Information technology on March 17, 2005 which is a warning to service providers not to mislead Consumers from selling 64kbps, 128Kbps connectivity options by brand name “Broadband". The details you will get on site http://pib.nic.in/release/release.asp?relid=7871
BSNL is having last mile copper connectivity till all individuals subscriber who are using their existing landline phone. By taking advantage of ADSL technology and Copper Connectivity, BSNL is introducing ADSL in 198 Cities in India.
Don’t Miss your Phone call while you are surfing Net ,BSNL’s High Speed Internet ( Broadband) Dataone
BSNL has introduced ADSL Broadband service by name Dataone.
Now user can afford to remain connected to internet always with the help of BSNL Broadband Dataone. There are no dialup charges, there is no ISP package, and most important that while you are online you will not miss any of your important phone calls. On same line you can use internet and you can initiate or receive the telephone call simultaneously.
On Dataone you can expect many more applications in future. Dataone connection will support the combination of Voice, Data, and Video Service. Internet is one of the applications in this. Users can expect Video conferencing, Internet games etc, which require high speed connectivity, Time shifted TV, Distance education, surveillance, and many more through this connectivity. This connectivity will open one new paradigm.
With the BSNL strength of existing last mile copper connectivity which is goldmine of BSNL things will look entirely different. BSNL has this connectivity network ready as on today which has capacity to deliver up to 24 MBPS with ADSL 2+ technology. Hardware resources are also ADSL 2+ compliant. So for any business need, bandwidth will be less likely to be an issue in near future.
Dataone package starts with Rs. 500/- for 256 Kbps home plan per month till Rs.9000/- for 2 MB Business Plan per month, depending on volume of data transfer, connectivity speed, single or Multi-user options. Both the incoming and out going data is taken in to account while volume is calculated and BSNL has also created a provision to display the extent of volume you have consumed and the balance for that month.
The additional volume of data will be charged extra if you exceed your opted plan. But I feel, for common users at present the data limits given by BSNL are just sufficient for the needs of the organizations. So there is no need to shell out extra money for additional volumes.
Till June 2005 you will not be charged for additional volume of Data. This is a promotional offer from BSNL. You will have to register your application at BSNL customer Service center for getting Broadband connection. After you register your application with BSNL, field staff of BSNL will test your telefone cable pair and decide whether it is suitable for broadband connection or needs replacement. After verifying cable pair you will be given a demand note for payment.
Customer Premise Equipment ( CPE)
Subscriber to ADSL will require an additional device which will be interfaced between your computer and ADSL line. This device will have an accessory called splitter which will isolate Data and telephone calls. This ADSL modem/router is either supplied by BSNL or the customer is free to buy from the market depending on the individual needs.
Buying BSNL modems is best option as it is economically priced at Rs.2000/- for outright purchase and also carry warrantee for two years. For those customers who don’t want to invest on ADSL modem, they can take these devices on rent by paying rent of Rs.100 per month. Installation of CPE (Customer Premises equipment) will be done by BSNL for modem/router supplied by BSNL.
Cost of Customer Premises equipment starts with Rs.2000 on wards till Rs. 25,000 depending on Facilities. Facilities are related to wireless connectivity access control, firewall (security device), etc. Customer has to audit what are the requirements of organization based on which he can choose the device. You can also contact BSNL if you find it difficult to choose the device. By choosing right CPE, the organization can control data volume, which in turn can help in keeping volume cost within limits.
Why BSNL for High Speed ADSL Connectivity?
After reading this information you may have realised by this time that service provider should have a robust infrastructure of high bandwidth, highly reliable network and a large access network so as to offer such high bandwidth applications.
BSNL, as the Number 1 telecom service provider, is in the process of setting up the Broadband network in 198 cities across India. Most of the infrastructural work has already been completed and the services have been rolled out in about 20 cities and likely to be rolled out in all the selected 198 cities by April, 2005. So far, BSNL has invested 700 Crores in Broadband project it is likely to multiply the investment in this sunrise business. This investment excludes BSNL’s goldmine last mile copper connectivity which is unmatchable. As per the latest information which we have received from corporate office equipments are already in transit and expected before 31st of March 2005 in all the respective exchanges as per the plan. The inclusion of Aurangabad in the selected cities has been a great favour from corporate office for diverting equipments besides the planned schedule based on request of GM BSNL Aurangabad.
Just to keep you informed, for Aurangabad Customers, who wish to subscribe to BSNL’s Broadband connection or who have already subscribed the Broadband connection of BSNL, Aurangabad BSNL is connected to parent Pune node. The basic connectivity to Pune is STM1 (155 Mbps), which is especially dedicated to Internet and from Pune to International Gateway the available bandwidth is 620 Mbps (STM 4). As such, even if all subscribers opt for higher end plans such as 2 MB or 1 MB or 512k, there will be more than sufficient bandwidth available for every user without any congestion in network.
Secondly, from subscriber to exchange, you require very well planned and laid copper connectivity for ADSL to work properly, which will deliver same quality of service in different weather conditions and during all the seasons and for years together and up to 24 MB with existing technology ADSL 2+. Third most important thing is that you have to be located within 5 Kms from exchange. Fortunately, with foresight of the Government Enterprise BSNL, you will find that most of the subscribers will fall within the limits of 5 Kms from the exchange due to the large number of exchanges spread over the entire Aurangabad territory, which are already in place and connected by optical fibre.
Hence, no user will be denied the fruits of broadband revolution. Anybody, anytime and anywhere will be capable of enjoying this facility. The real investment made by BSNL is in the core infrastructure. The cost of the international bandwidth is also to be borne by BSNL on top of the above cost. But, with the might of BSNL and the commitment to roll out the Broadband services, it is a win-win situation for the customers.
