PURPOSE:To continuously execute on-line processing even if abnormality is generated on a using communication line by using a substitutive communication line to continue communication between an automatic teller machine and a computer when the abnormality is generated. CONSTITUTION:A communication processing part 23 connected to a MODEM device 9 with an NCU through a communication line 8 and connected also a switching connecting equipment 11 through a control line 14 decides abnormality on a private line 12 to be a primary communication line, and if abnormality is generated on the line 12, outputs a switching control signal to the equipment 11. At the time of receiving the switching control signal through the control line 11, the equipment 11 disconnects the line 10 from the line 12 and connects the line 10 to a public line 13. Both the lines 12, 13 are connected to a host computer 25 arranged in a computer center 24 or the like to execute data communication between the machine 1 and the host computer 25. |
