2.2 Permanent connection

TP1/Client allows the message exchange by maintaining connection between a CUP and the server. This connection method is called permanent connection. You can specify logical terminals for TP1/Server and VOS3 XDM/DCCM3 as remote servers for which you request to establish a permanent connection. The permanent connection decreases control packets for establishing and releasing connection, providing effective communication.

For brevity, this manual calls VOS3 XDM/DCCM3 simply DCCM3.
