I am not sure the exact speed for T lines as it is up to the providers. T lines are SDSL lines. I think 1 is usualy arround 750K 2 is about 1.2Gig and 3 is about 1.7 Gig (More or less and any of those). The cost is very high for any of these. T-1 can run about $70 month. T-2 can be about $100 month. Again price is determined by the provider and my examples could be off. T lines are usualy used in the buisness world. You best bet for home use would be ADSL or cable. ADSL can be as much as $30-$50 month. Speeds up to 3Gig\357k. Cable is also about the same price as DSL but with speeds up to 6Gig\350K. Again this depends on the providers and your location. SDSL --> Symetrical Digital Subscriber Line = Same speed up and down ADSL --> Asymetrical Digital Subscriber Line = Different speeds up and down Hope this helps -Del
