I provision data customer-premise equipment for a national (but not major) ILEC, including Internet, MPLS and VoIP.
In other words, I help you get porn while at work.
I also provision equipment in our multiple colocation facilities.
In other words, we provide services to the guys who provide the porn.
Finally, I provision firewalls for small and medium businesses.
In other words, I block your access to said porn.
(actually, I don't think we have any "real" porn customers in our facilities)
