T1 is an old but extremely reliable technology from the 1960's. A symmetrical (same up and down speed) 1.544 Meg connection T-1's can be bonded together usually up to 8 T-1s for a 12 Meg symmetrical connection. Extremely reliable, and somewhat expensive by home consumer standards.
DSL or (Digital Subscriber Line) is offered by your phone company over copper based facilities. (the DSLAM'S Digital Subscriber Line Acces Multiplexer may be fiber fed) DSL can go as fast as 100 Meg Asymmetrical connections. but that is extremely short distances from the DSLAM. 25 or 50 meg down with up to 8 Meg up are realistic speeds, although for long distances from the DSLAM, the speeds are often not much over 3Meg or even 1.5 meg down and some smaller number upload speed. The further away you are from the DSLAM the slower you will get. Why not just build a nice DSLAM just outside your door? Sure man, just for you.. be happy to. just give me a million dollars and I will build one inside your house. All you need to do is pay for that 1 million dollars of equipment. Oh, you say you have a neighbor or 2 within range.. sure they can help pay for it.:laughing:
Hey I got a big ole fiber real close to my house!. OK. I have a big ole gasoline pipeline going by my house.. I guess I will just "tap in" to that. Uh, huh. Having a fiber going by you front yard means squat about giving you service. Just like having an 750KV power line going by your house means squat. I can assure you that a big point to point fiber going by a big business that was to buy a ton of broadband does not mean squat either. Even there the money is not there to get the fiber cut, and all of the expensive equipment that would be required to break out service even for them from a 10GIG DWDM (Dense Wave Division Multiplex) fiber circuit. Talk about drinking from a firehose..
Now if you want a 10Gig Ethernet connection over fiber, well I used to sell those. I could make you a deal on that. You got $10,000 a month? I could fix you right up. Well not anymore. I don't work for the phone company now. But I know who to call if you need that 10Gig connection.
So anyway I hope these tidbits of info helped a bit. I have 25Meg down 5Meg up here from the local cable company. I could have 75Meg for an additional $10 per month. but I cant find any use for more than the 25Meg I have now.
