Article on Broadband Introduction: What is Broadband? Broadband is considered to correspond to transmission speeds equal to or greater than 256 kbit/s, and some operators even label basic rate ISDN (at 144 kbit/s) as a “type of broadband”. For India, the Telecom Regulatory Authority of India has recently recommended the following definition: Broad band is defined as an ‘always-on data connection’ that is able to support various interactive services, and has the capability of a minimum download speed of 256 kilobits per second. TRAI expects to revise the definition in the future.
Broadband is defined as
a pipe through which one can provide multiple services ranging from plain
voice to Internet to video on demand (VoD). A broadband service facilitates multiple telecom services through a single copper cable interface. Initially, BSNL's broadband package shall include services like telephone, satellite TV channels, internet, Video on Demand (VoD), Audio on Demand (AoD) and video conferencing. How is broadband access provided? High-speed data connectivity can be provided by both wired connections and wireless connections. Wired connections account for the vast majority (over 98%) of current connections, although wireless technologies are starting to grow quickly. Of the fixed line connections, digital subscriber line (DSL) and cable modem technologies are the most popular, according to the ITU. Until '00, the majority of broadband users were using cable modems, and this is still the most popular form of access in North America. But worldwide, ADSL now accounts for more than half the connections, being particularly popular in Asia and Western Europe. In DSL - ADSL is one of several versions of DSL - the ordinary copper pair that connects the plain old telephone at the subscriber premises can be used to carry data at high speeds. Dataone service BSNL is in the process of commissioning of a world class, multi-gigabit, multi-protocol, convergent IP infrastructure through National Internet Backbone–II (NIB-II), that will provide convergent services through the same backbone and broadband access network. The Broadband service will be available on DSL technology (on the same copper cable that is used for connecting telephone), on a countrywide basis spanning 198 cities. In terms of infrastructure for broadband services NIB-II would put India at par with more advanced nations. The services that would be supported includes always-on broadband access to the Internet for residential and business customers, Content based services, Video multicasting, Video-on-demand and Interactive gaming, Audio and Video conferencing, IP Telephony, Distance learning, Messaging: plain and feature rich, Multi-site MPLS VPNs with Quality of Service (QoS) guarantees.

It shall provide the customer with the option to select the services through web server · To provide both pre-paid and post paid broadband services Technical Capability of the Backbone The Broadband Service will be given through the state of the art Multi Protocol Label Switching (MPLS) based IP Infrastructure, which is designed to provide reliable routes to cover all possible destinations within and outside the country. Layer 1 of the network will consist of a high speed Backbone comprising of 24 powerful Core Routers connected with high speed 2.5 Gbps(STM-16) links. The routers are located on the national DWDM network interfacing at STM-16 optical level to provide for high transmission speeds. What advantage does MPLS have over other Technologies? MPLS VPN is a technology that allows a service provider like BSNL to have complete control over parameters that are critical to offering its customers service guarantees with regard to bandwidth throughputs, latencies and availability. Services available through Broadband · High speed Internet Access: This is the always-on Internet access service with speed ranging from 256 kbps to 8 Mbps. · Bandwidth on Demand: This will facilitate customer to change bandwidth as per his / her requirement. For example a customer with 256 kbps can change to 1 Mbps during the video Conferencing session. · Multicasting: This is to provide video multicast services for application in distance education, telemedicine etc · Dial VPN Service: This service allows remote users to access their private network securely over the NIB-II infrastructure. · Video and Audio Conferencing: Content based Services: Like Video on Demand, Interactive Gaming, Live and time shifted TV Services available through Broadband What the customer needs in order to be able to use Broadband? · BSNL's Bfone (Basic phone) connection · Personal Computer with 10/100 Ethernet Port · ADSL CPE (Customer Premise Equipment). This can be taken from BSNL at nominal rental per month.
Question and Answer on Broadband Services: What is BSNL Data One Broadband Service? 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. What is ADSL? 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. What is ‘always-on’ service? Will there be call charges? ‘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.
How fast is ADSL compared to normal dial-up, ISDN and DIAS connection? If you are using a connection with 1 Mbps down load speed then you are having a speed that is 17.5 times faster that normal dial-up, about 8 times faster than ISDN and about 4 times faster than DIAS. What are the benefits of ADSL? o Fast downloads o At least 4.5 times and 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 Do I need a separate line for ADSL? 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. Can I use both phone and ADSL together? 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. What is a CPE? How do I get it? CPE stands for Customer Premise Equipment. This would consist of an ADSL modem/router and a stand-alone or a build in splitter to separate the telephone and broadband connections. My friend has ADSL but BSNL in my city says I cannot! 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 Data One 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. What is download/upload? 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 Why are the download/upload rates different? 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) When Dataone is expected to rollout and what shall be the tariff? Broadband service Dataone is expected to rollout in more than 100 cities from December 2004 in a phased manner. It's tariff will be most competitive in the Industry. Where can I get help about DataOne service? You can call 24 hours helpline number: 1600 424 1600 What kind of PC do I need to run ADSL? Most present day
configurations will run ADSL. The following minimum is, however,
recommended: How do I connect to ADSL? 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 What is a splitter? Do I need one? 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.
