This section explains MCF processes used by UAPs. When UAPs exchange messages, the following MCF service processes are used:

• MCF communication process
  This system process is used when the local OpenTP1 system communicates with the remote system.
  
• Application startup process
  This system process is used when the OpenTP1 system exchanges messages internally.
  

The reasons why MCF processes are classified as shown above are:

1. The load of processes used for MCF communication can be distributed because the system processes are separated for external and internal communication.
2. The process for internal communication is not effected while MCF communication processes cannot be used due to a communication protocol error.

The figure below shows the outline of MCF processes used by UAPs.
