The compartmentalization of the different functions provides the platform to divide IMS Connect into the different components and keep the functions isolated and modular. Because IMS Connect performs several distinct communication functions, TCP/IP client communication, IMS OTMA communication, and IMSplex communication, the exits are involved in all instances, because message manipulation is a factor in both directions.
