The wan provider maps the DLCI to the IP of the FR switch at the opposite end through special tables.. Furthermore, the Frame Relay header is stipped off when entering the cloud and travels around via regualr IP or ATM, etc. The FR header is then put back on once it reached the opposite FR switch. They police your speed with CAR.
