I just ran some quick bandwidth tests and found that my upload/download performance to servers across the country are ~500k/sec down, 100k/sec up. Granted my specific cable modem's upload doesn't quite exceed T1 spec; but for my uses the download bandwidth more than makes up for it IMO. I also understand that I tested during off-peak hours; but generally I top out at ~700k/sec down and ~120k/sec up and rarely fall below 300k/sec down and 60k/sec up.
I thought that T1's advantages over cable and DSL were due to 24 channels instead of a single channel. In reading howstuffworks, it seems that a single channel is equated to a 8k/sec data transfer rate. If my understanding is correct, a T1, 1.5mbit SDSL, and any other connection offering 192k/sec transfer caps for downloads and uploads are all equivalent.
So what is it about T1's that give them such a high premium? (Excluding all wiring costs, since IIRC T1's use fiber optic before being split to coaxial.)
And if bandwidth is the single measure of line speed, am I correct in terming a 1.544mbit SDSL line and T1 line equivalent?
Edit: I just started wondering about this for some reason. Honestly, I don't really care what lines I use so long as they're fast.
