Literally drafts of the cable plant, as it occurs on the street. I worked for a firm who contracted through various ISPs to digitize their equipment plant drafts via AutoCAD and SPATIALnet back in 2010. Our contract ended up falling through. I'm not fully sure why, but I was part of a hiring frenzy in the firm's area, that ended up laying off a bunch of people after the Comcast contract fell through. There was a class action and everything, they paid for training or unemployment for two years.

It wasn't that bad of a job. I worked four 10s and could grab coffee, blast some music, and knock out the cable plant. Accuracy and speed are all that really mattered. The worst part was how picky drafting standards were and how poor the Python scripts they cobbled into AutoCAD were at actually meeting their standards. Lots of manual offsetting. I wish I had known enough Python at the time, because I might've been able to get a foot into their infra staff or something by improving the drafting workflow.
