In general, the PMI JAVA client is implemented based on a personal computer (hereinafter, referred to as a PC) or a workstation based on a client server model.

It provides transport control port / Internet protocol (abbreviated as TCP / IP) connection to the server on the workstation. The multi-client support enables convenient access through the network. In addition, the JAVA language provides a familiar interface due to the additional features obtained, namely, the cloth platform structure and the ability to execute PMI JAVA clients through existing web blisters.

The conventional electronic switch system provides a default 0 to 15 cathode ray tube (abbreviated as CRT) and an RS-232C port for a printer. The PMI is implemented on a workstation. It provides a Local Area Network (LAN) port for interfacing with the LAN.

In addition, since the graphical user interface is not supported for operation through the existing exchange dummy terminal, it is insufficient to provide help related to operation, and all output messages are output in one window, and it is difficult to check a specific message because there is no scroll function. Due to the text environment, there is a limit to the information that can be provided, making it difficult to add new functions.

In the case of the PMI implemented in the workstation, only a single connection is allowed when connecting to the switchboard PMI server. Therefore, when implementing the client server model through TCP / IP, the maximum function due to the design problem was not utilized. There is a problem that there is a big constraint on the scalability as it does not support.
