This is a pretty good idea. You could probably even get a night or weekend shift in a NOC for a small to midsize ISP if you have the networking chops. It usually goes something like this: wait for alarm from monitoring, run a few circuit tests, call upstream provider so they can tell you that they are working on it, inform customer, repeat. On an uneventful night, you can end up with quite a bit of free time.
