that number is quite valid, in fact here is an article from PBS from Monday that I just found! Also, I never said they were "given" $200 billion. That's not how it works, stop adding little words here and there, it may be helpful to use direct quotes, as you seem to be mixing things up with your paraphrasing.

I got your point about 5 posts ago and addressed it. I addressed it again in every post. I have given you reasons why you will never see fibre in your home.


I still haven't said I'm expecting fibre to homes. If I did, please refer me to that post and I will admit I was mistaken. I already looked, and I'm positive that I never said that - mainly because I don't believe it either. Thanks for emphasizing this point. It would have been just as useful to "convince" me that using a hybrid of gold and cans on strings would not work.

What I said from the very beginning was a hybrid system.

FINALLY, Something I'm an expert in!!!!

O.k., Cable companies use a standard called D.O.C.S.I.S. This standard basically says how cable modems work on a hybrid fiber-coaz network. This standard also has caps on them. That being said DOCSIS also dictates that there has to be caps on the modem.

When a cable modem first comes online, it goes through whats called DHCP. Basically this is a handshaking process where the modem broadcasts out, saying I'm over here. The server responds saying, yea, what do you want. Modem says I want online, server says o.k., let me check billing, o.k. that checks out, heres a config file, modem says o.k. thanks.

That config file is known as a TFTP file. It has the parameters dictacted by billing as to what speeds the modem needs to have, and what server it needs to go to to have the client get an ip. Client being your computer(router).

Now then. Back in the day, there was a big stink about comcast rolling out servers that monitored bandwidth. Can't remember the name of it, but Adelphia also started to secretly roll it out. THankfully, Adelphia Techs didn't know how to configure it properly, so they backed off it. Basically, it wound up doing so much monitoring, that it slowed the people that it was monitoring so bad, that they took it out.

As far as FTTH goes(Fiber To The Home) This is a VERY feasible thing for the telephone companies to do in the cities of the U.S. That being said, Cable companies are not going to do it. DOCSIS is rolling out a new standard DOCSIS 3, which Significantly changes how the way that the frequency spectrum is broken up, basically pushing through more data tighter frequencies. This in turn will allow them to provide larger bandwidth between the home and the CMTS(where it turns into fiber).

This being said, if your paying for 8 meg, and your only getting 1meg, check your signal levels on the modem.
192.168.100.1..., most modems have an internal page that tells you what the signals are. Docsis states that they should be:
upstream - 8 to 58 ---looks good at around 45
downstream - 0 +- 15 ---- closer to 0 the better
Downstream SNR - 27 - 35.

I would type more but my wife wants me off this to go grocery shopping.

Camain

I work for an ISP in Moses Lake, WA. We provide internet over our local fiber network as well as wireless broadband. We state very clearly there is a 15gig transfer limit monthly. That is an enormous amount of bandwidth. 99% of our users do not even come close. I see that everyone is talking about Comcast. Does it state ANYWHERE in the fine print about bandwidth usage? I use Qwest DSL at my house and I think they even state a limit if you read deep enough.

Admittedly, I know little about software side of things, but on the flip side, I question your networking knowledge.

I've read up on DOCSIS and it would appear to be specifically relating to the use of wavelengths when using the same cable network that broadcasts TV as well as broadband internet access from the head end. The actual core networks, regardless what is being pumped over it, are set up the same.

Albeit, you Yanks have to be different and where the rest of the world uses SDH architecture, the US uses a slightly different standard called SONET. Same thing, just slightly different way's of working. Your basic unit is 1.54 Mb/s whereas in europe, it is 2.048 Mb/s. The higher order transmission packages are just multiples of these units.

Fibre into homes is unnecessary and expensive. Utilising existing coaxial connections into homes (assuming you have a cable connection), one can squeeze alot more down it. Electrical connections can support up too 140 Mb/s. Also, at least in the UK, the networks are fibred from the DP (street cabinet) where there will be a multiplexor to transmit data up and down in STM-1's for broadcast to the head end where larger mux's will package it up for the core network.

Assuming you had fibre into home, not only would you need new equipment at home that could turn optical signals into electrical, but you would also need to replace all the corresponding electrical terminating equipment at exchange sites into optical. A huge, expensive logistical task that, in all honesty, will not happen in the near to medium future.

As far as the CORE network goes, yes, all cable companies use fiber optics. DOCSIS standards only apply to the equipment that is digitized going through the headend. Be it, the HDTV, Digital channels, Phone service, Security, or Phone. All of it has to adere to DOCSIS in that regard. As far as the standard cable goes, it doesn't. Thats usually the reason why you can have fuzzy channels on these, vs Digital, which basically is either there or not not. As far as how this is applied at the cable side of things. I admit, as far as networking goes, I am not an expert. I do know though that the ISP's that I used to work for, did use Sonet alot, as well as BGP, and OSPF. In Europe, last I saw, there was a EuroDOCSIS which had slightly different configs then the U.S. DOCSIS.

As far as FTTH, I still say that you will see this in the large cities. A cable company puts $1000 in a customers house for equipment, Cable modem- $100, Digital recorder- $400, standard digital box, $150. These numbers quickly add up. Because the cable companies are now starting to compete(in the U.S.) with the phone companies, the phone companies are starting to loose a light profit from this. Notice, I say a little, Only because all of the Cable companies use the phone companies as back end support. (they just make there money a little differently). Regardless, because of this, the phone companies want it all to be on there network. Meaning, Phone, TV, and internet, and they want it through one pipe. This is why several phone companies have rolled this service out. You won't see it in the sticks, only in the cities, and only in the most affluent neighborhoods.

As far as The RIAA and the MPA goes, you don't get introuble from downloading. You get in trouble from sharing copyrighted material. This is how is works. Both companies use outsourced 3rd parties to prowl around and look for there content they control. Lets take edonkey as an example. The go on there, do a search for a file(Star Wars 3) and start downloading it. Well, as there downloading it, from you, who happen to be a star wars junkie, as the data that is being transferred is being transferred via TCP/IP ( another protocol). The Protocol, basically states that every packet has an id tagged to it, and that theres a return address on it(which is your IP address.) Anyone that is on the internet has an IP address. These IP's are handed out to you from the ISP. Now then. They do whats called packet sniffing, on there network, basically ripping the data that your transferring to them apart, and get your IP address.

On a cable network, This IP address is bound to a specific device, through your MAC address. Every device that gets on the internet has one. This is basically something similar to a serial number of the device, be it dial up modem, network card, router, etc.

This being said, they turn your IP over the MPAA, which in turn lodges a complaint with the ISP stating that IP 24.24.24.24(ex) was sharing (blah) on such and such day. We want that person. The ISP looks on the CMTS for the ip, which correlates back to the machine address of your NIC. The NIC mac address ties back to your cable modem, the Cable modem goes back to your account, and WHAM, you just go fingered.

This being said Of the 3 cable ISP's that I worked for, only one had the capability to go back, look at the IP, and see who had it on a specific date, VS currently having it. The other 2 ISPs, which I won't name, if I was being sued by the RIAA or MPAA, I would fight them tooth and nail. the 1 that coule track, could only track back a month, so if the supena came after that mark, then they would be just as unreliable.

This is the reason why I use newsgroups vs filesharing. While you do have added expense with most decent newsgroups, You either A) settling with these pricks, or B) Fighting them, costs alot more. They have enough money to keep you in court for a VERY long time, and loosing your case could cost
