>>> But we already have such a slow lane. And it already made the internet less free and less useful.

I'm pretty sure you can still get ISDN lines from your local telecom provider. I know a long time ago there was talk of binding ISDN lines to together to increase upload and download speeds. This was right around the time DSL was blowing up so I'm sure it got lost in the wave of DSL hype.

Of course compared to DSL. GigaFiber, or any of the current technologies, it's downright pathetic.




Bonded ISDN lines are called a PRI (also known as a T1). A normal ISDN BRI consists of one D-channel and two B-channels. A T1 was one D-channel and 24 B-channels. You could also bond multiple T1s together; it was effectively a long-distance serial link that operated off the telephone network.

Technically you could also bond multiple BRIs together, but pretty quickly it made more sense to just provision a PRI with some of the B-channels disabled (also known as a fractional T1).


I used to know this stuff back in my Net+ certification days.... like 15 years ago. Now I can't remember what BRI and PRI are - Basic Rate something?
