I worked at an ISP that gave dedicated ISDN and 56k frame relay lines as a benefit in the late 90's. T1 would've been amazing!

I worked for an ISP back in around '98, and they offered to let me terminate a T1 there if I covered the line. I got a contract from the phone company for $205/mo for the T1 and got it all set up, but they were billing me $250/mo for the line. A couple months in DSL dropped, and I got out of the T1 contract because they said they couldn't honor the contract they wrote because $250/mo was the regulated minimum price, and I got 768K DSL for $70/mo. At the time everyone was speculating that DSL wouldn't work (crosstalk across pairs as multiple people in a bundle use DSL will cause it to fail), but they were quickly proven wrong.

Back in the day people on forums would list T1 line in their signature. My ISDN line was not worthy!

I had 1.5 Mbps DSL in 1999, and I think nearly all of my co-workers either had that or a cable modem with similar speed. I think T1s were like 5x the price for the same download speed.

What market did you have 1.5mbit dsl in, in 1999? GTE in LA county offered 768k/768k symmetric. In 1999. I can't remember when that was increased, but it was after GTE got bought out.

Calgary. I remember it being asymmetric, probably 256 or 512 up.

Cadvision? 3mbps cable (sadly Rogers) wasn't impossible at the time.

Nucleus!
