T1 wasn't cheap nor ubiquitous. I ran the networking for the degree granting
public colleges in NJ (which on the whole is a fairly metropolitan area) but there were
places we couldn't get it.
It was also expensive. Old school copper T1 required repeaters every quarter mile or so.
Debugging could be fun. At least our telco (NJ Bell) back then could move the loop
back around while I did tests to tell them where the line was failing.
And yeah, I live in one of those backwaters now. No cable, no fiber optic anything. I
use two DSL lines to get an aggregate 20M down 1.5M up. That's the best the vesiges
of the old GTE telco down here can do.
ATT has fiber in communities down the road but we're too sparse to attract their
interest. Comcast won't even pull in a local drop from the main road.
