PURPOSE:To cut off quickly a telephone circuit without giving any load to a main control part by deciding the code added to the final data given from a computer center. CONSTITUTION:A cut-off deciding part 36 decides the code added to the terminal of the final data given from a computer center 27 and gives a cut-off command to a circuit control part 29. Then the part 29 sends the received data to the part 36 when a mode selection part 35 is set in a mode where a telephone circuit is cut off with decision done by an FTX code showing the final data. The part 36 decides the reception of the final data when the received data contains the ETX code and then gives a command to the part 29 to cut the connection of the telephone circuit. Thus it is possible to decide the cutting time point of the telephone circuit from the ETX code added to the final data. This ensures the quick cut-off of a telephone circuit. |
