Access Control Of Destination Dispatched Elevator System

For standard elevator systems, I'm fairly well versed in controlling them from an electronic access control system via contact closures. However, destination dispatched elevator systems are a new thing for me. 

For access control of a destination dispatched elevator system, does the EAC system communicate to the elevator control system via TCP/IP, negating the need for EAC panels in elevator control rooms?  

Any insight that those familiar with destination dispatched elevator systems can provide is greatly appreciated.
