In the early 2000s, it was pretty uncommon to bring in all those PRIs from the cities, most telcos supported foreign exchanges through a combination of DMS-100 (brand name Centrex in Ameritech world) features and circuits. Near the end of the retail dial-up ISP, it was not uncommon to cover entire states through that and have them come into groups of PRIs.
The outfit I worked for started in 1990 and had actual POPs with aggregated 3Com, Livingston and Micom serial aggregators that went to a central location over leased lines. They had 1500 lines between retail SLIP/PPP and a couple bulletin boards. That was quite the monster.
- tptacek 3y agoI don't know if this disagrees with you or not, but we were done with individual dial-up modems by early 1996, and spent most of that year on Ascend's platform (the Livingston PM3's the next year; I left in the middle of 1997 to go work for a vulnerability lab, and I definitely set up a bunch of PM3's, so that's the timing worked out for me).
