I'm a cellular systems technician, I typically spend ~6 - 8 hours a day in this corner setting up systems that the engineering team designs to make sure they work before having them shipped out to whichever mobile carrier. Spent the majority of today drowning in IP addresses trying to get an SNMP system working (basically a system that monitors a cell tower / site for malfunctioning equipment and then emails that info to the carrier's engineers / techs so they know what's wrong where and when).
