CONNECTION HOLD CONTROL SYSTEM

A connection hold control system is adapted to a data communication system in which a data communication is alternately made between a first terminal (TE#1) and a second terminal (TE#2) and between the first terminal and a third terminal (TE#3), where each of the first through third terminals is coupled to a communication network (60) via a terminal adapter (TA#1-TA#3). The connection hold control system includes a hold part (1), provided within a first terminal adapter (TA#1) which is coupled to the first terminal (TE#1), for holding a first channel which connects the first and second terminals (TE#2, TE#3) via the communication network (60) and the terminal adapters (TA#1-TA#3) after a data communication from the first terminal to the second terminal ends, and a connect part (2), provided within the first terminal adapter (TA#1), 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.
