TCP/IP and OSI TP can be used as communication protocols for OpenTP1 client/server mode communication. This section outlines communication using OSI TP as the communication protocol. This communication requires TP1/NET/Library, TP1/NET/OSI-TP-Extended, and products for managing communication under OSI TP. In addition, an OpenTP1 system service (XATMI communication service) is necessary.

Client/server mode communication using OSI TP as the communication protocol is possible only when the basic facility of the OpenTP1 is the TP1/Server Base. If the TP1/LiNK is used, OSI TP communication is impossible.

The figure below shows the concept of client/server mode communication using OSI TP.
