Dear All,
Can any one provide me with some guidelines to how does a Cable Internet thing work ? Has any one done such a setup before and what all things are required for the setup.
Thanks for your valuable time.

In Mumbai it's ethernet. You need a network card. Some ISP's may have a special cable modem, but you'll have to check with the specific ISP.
Any ideas what all goes on such a setup (Extended LAN) or Cable internet ?

Most cable modems directly connect to the Ethernet Cable, so Linux compatibility shouldn't be a problem right?
Should I buy or rent a cable modem? Are there people selling old cable modems?

Hi, I dont think you need to buy a cable modem unless you require a high speed line or thinking of providing connections further down the line. In most cases you need to buy a lan card and then ask your cable-guy to give the connection to you. If you buy a NIC yourself, it would cost between 250 - 350 rs. but people often are charged 700 as nic price (this i have seen in 3 cases). make sure you first ask him price of nic he is offering and then tell him that you are buying it yourself...so that he would deduct that amount from your installation charges. the person would then put the ethernet cable from a nearest hub to your pc.
even if you buy the cable modem from him/other source, i doubt how many isps in mumbai allow that, even if they do, keep an eye on your transfer rates as the cable modem can be bandwidth throttled easily by upstream host (ISP). Buying modem could be expensive and speed benefits would not be much IMHO

If the ISP is providing data over COAX, then you need a cable modem. If you are on an Ethernet LAN, you need only the NIC.

That depends on the brand. I recommend Intel EEPro100+/3Com 905c NICs.

This is a common ethernet LAN. If you ever go in for this arrangement, make sure your ISP uses switches and the distance between any two switches is less than 100 m.

That depends on the connectivity you need. You really think an Ethernet connection cannot be throttled? Of course, personally the biggest reason I am on a cable modem is because I get a routed static IP. I do not care to be a second class netizen behind a NAT.

The only issue you will have is if your ISP requires the use of PPPoE clones. Normal DOCSIS standard cable modems plug into an Ethernet interface,

I would buy a fresh modem (avoid the surfboard 4200, because the firmware has a bug and most ISPs won't upgrade to a new firmware. You cannot do the upgrade yourself.).

Internet Cable Modems do not connect to the Ethernet Cable. They basically connect to the Co-axial cables coming out of the Cable ISP (Containing TV Signals and Internet Signals both) and split them into Ethernet and Cable Signals.

Yeap. Compatiblity with OS is not a concern.

Sorry. COAX is split by the splitter. One line goes to the modem while the other goes to the TV set. The cable modem is a bridge. It bridges the ATM over Coax interface to the Ethernet interface.

Alright, now I have to ask. What is the problem that you're trying to solve?
hii, mostly in mumbai it is just and extended lan network , with one server that connects to net , rest of the computers access net via proxy .

As Philip pointed out...its ethernet here...most isps use cable modems to bring the main line one of the convenient location and then connect the hub to the cable modem this hub is used to distribute the lines further. many times, hubs are also cascaded if desired.
seems that there is a firm "global network solutions" somewhere near chembur. they have tied up with local cable (tv) people to distribute locally. they also have provided a web based login system on which, each local isp puts his name. so i login to my isp and my isp has logged on to his isp via same tech..
and a linux based proxy web server is given to each location which handles local user database and proxying.
also another company is wincablenet, they have a exe program that handles logins...this is however not well supported by linux.
third isp i have seen uses different technology. he uses PPPoE (PPP over Ethernet) and provides a ppp dialer to each client. once the client is connected via pppoe, he can start surfing...
these isps are conected using atm or adsl to their isps but the basic infrastructre provided at the user's end is lean and mean ethernet (twisted pair/10-100mbps)

Yeap, Hathway provides internet service through CMTS and Cable Modems on some places. Has any one been involved in similar setup before, which could be of help to me. Currently i am trying to analyse how Internet can be distributed along with Cable TV Channels and what all equipments would be required for such a setup.

Yes. I have been involved with running a cable ISP earlier.

Internet over CATV lines (coax) uses different frequency bands from the TV signals. http://www.google.com/search?q=docsis should be a starting point for you. Basically, you need a CMTS [Cable Modem Termination System] (basically a router with coax ports and ATM support), cable modems, a bit of ethernet/usb for the modem to connect to the PC, a switch to connect your servers and CMTS to the edge router. Specifics will depend on a lot of factors, including the service(s) you provide, the IPs you allocate, the specific systems you buy....
Feel free to ask further questions.

Hmmm, could you provide more specifics? A lot more specific details? With the lack of details in this mail, the best recommendation I can point you to is http://www.google.com/
