PURPOSE:To save the cost of line and to reduce line accommodation, by switching the control to other control procedure, when an information processor with different control procedure cannot correspond to an incoming call through the connection on a common line with a control procedure. CONSTITUTION:An information processor 1 is connected to a plurality of information processors 3, 4 having different control means via a common line connected to an exchange line network. The processor 1 executes the processing according to the control means of the processor 3 with the assumption that the incoming call from the predetermined device 3 is present. If the correspondence with the opposing information processor cannot be made with the processing, the processing according to the control procedure of the device 4 is executed. |
