Little towns were fun. Had a buddy at the regional ISP (that became a CLEC but that was later) tell me how they had bought all the remaining capacity on the switches in 6 of the 10 towns they served. There's wasn't any ISDN out to these places yet, so they had to have old school closets full of modems in buildings near each CO in these towns. They had to do a microwave backhaul from one of the closets to their network because AT&T couldn't sell them
any data lines into or out of that CO.
Helped them shuck and rack the USR courier modems for a couple closet expansions. they'd got a local carpenter to make them a standard 16 wide modem board carrier that was very slick. Still, punching down lines and getting all that stuff woven together was tedious.
