Example pricing below (i think we all know who it is :D )

Transit: 100Mbps $3,000/month unlimited $3,500 Install
GigE $20,000/month unlimited $7,500 Install
Transport: 100Mbps $1,000/month unlimited $1,000 Install
GigE $10,000/month unlimited $5,000 Install

Can someone tell me the difference between Transit and Transport?

Cheers.
