Abstract

A connection hold control system is adapted to a data communication system in which a data communication is alternately made between a first terminal and a second terminal and between the first terminal and a third terminal, where each of the first through third terminals is coupled to a communication network via a terminal adapter. The connection hold control system includes a hold part, provided within a first terminal adapter which is coupled to the first terminal, for holding a first channel which connects the first and second terminals via the communication network and the terminal adapters after a data communication from the first terminal to the second terminal ends, and a connect part, provided within the first terminal adapter, for connecting the first and second terminals via the first channel if a data communication from the first terminal to the third terminal via a second channel ends within a predetermined time after the data communication from the first terminal to the second terminal ends.
