I'm working a paper for school and I'm working on the WAN requirements for a company that needs to send large files to each office in each country. I'm leaning towards using SONET to satisfy the speed requirements, but with my limited searching and lack of time, I'm having trouble finding how exactly the SONNET connection will connect up with the LAN. I know we use CSU/DSU with our leased T1 lines at work, but I haven't seen what the equivalent piece of equipment that a SONNET/OC type network would use. I know I'm being lazy, but hey its Sunday
