I have always heard trunk lines (T1, T3, etc) are "more stable" and "more reliable". Comcast has a 20/5 "Residential" package for say $90/month. Than they offer a "Business Class" package with the same bandwidth for say $130/month. Then you have a Verizon T3 (3.0/3.0) for say $700/month
As a business why would I even consider a T3 at $700/month when (if I could get it) a Comcast "Residential" package at 20/5 has a lot more bandwidth?
What is "more stable" and "more reliable" when it comes to a T3? Different switches? Better routing? Why in the world would a business choose a T3 over much cheaper alternatives and what is the difference between "Residential" class and "Business" class?
